Well, got started tonight. Here's current setup
350 bored .030 over (block number 3970010)
882 heads, cast iron intake, small cam, very small cam
stock converter
In the next few days....
062 Vortecs all machined and safe to .550 lift, valve job, resurfaced...
Performer RPM Intake, Crane 100182 Cam, Edelbrock 1411 Carburetor
Boss Hog 2200-2800 Converter
Got the engine and TH350 out tonight
-
This engine will be chevy orange and that th350 will be silver next week.
-
Movin right along. Dang that engine/trans looks clean.
-
Here be the vortecs
-
Another shot of the vortecs. The cam I pulled out is a Crane 260H10 which was a single pattern cam with .427 lift, 204 duration at 0.050 on a 110 Lobe Separation. It did pull hard out of the hole even with the stock cast iron intake but ran out of steam past 3200.
-
A-ha! 4 bolt main, I was actually betting I had 2 bolt mains!
-
I love this air cleaner I got. 14 incher powdercoated in translucent black over chrome. This pic does NOT do the air cleaner justice. I'm debating a Turbo Fire 350/350hp decal. And I got the 14x4 Element off ebay with a few other things.
-
looking good ma man :)
-
I know it's not much, but I painted my lettering on the manifold!
-
Right on man, I wish I was able to soup up my 82shortbed like yours! I just got done putting edelbrock performer 2101 intake, and a edelbrock carb on my new motor. One day I'll get enough $ to build up my 400 sb!
How long did it take you to pull the motor/trans?
Painted intake looks smooth...

We had that motor out in about 2½ hours, would have been quicker if the motor had been cool. The motor should be together tomorrow night, I cleaned my firewall, fenders, and basically anything left after we took the motor out with oven cleaner, now i'm gonna flat black all under the hood tomorrow as well as paint the motor
-
Great progress! I hope your motor gets a sizeable increase in power. I was glad, nervous, anxious and relieved after I had the cam and heads done in my truck. It's a major upgrade!
-
This bad boy went in tonight
-
Pic doesn't do this justice IMO. The flat black is such an improvement over the gloss black that was covering my fenderwells and firewall.
-
Showing some love for Chevy orange...more to come!
-
Getting ready for the splash of color!
-
Primed up and ready for orange and clearcoat!!! :D. I'm getting more and more anxious as this progresses.
-
you will be happy with the outcome of the 062 heads, thats what im running, recent hotrod magazine did a study on the 062's and a custom grind cam advanced 4 degrees, pulled 423ft/lb 392hp with a performer rpm and stock lowend
-
Saw this at work today, was chrome, got some tape, and felt creative.
-
This is such a work of art! Every time I look I can't help but grin like a fool!
-
Pretty isn't it? I must say so!
-
Check out the powdercoated water neck and the sweet detailed manifold!
-
New aluminum radiator and the dual 12's to keep her nice and cool!
-
throw a water pump, and the pulley and crank pulley. Also a chrome alternator bracket, and BAM!
-
Looks very nice. Can't wait to hear it. I can't keep checking in on this thread. It's making me want to work on my engine and I don't have the $$$. :'( LOL.
-
Let's throw an Edelbrock Carb on here!
-
Looks pretty good to me!
-
I had these bad boys media blasted...for free! I primed and painted them with VHT for headers.
-
TH350 hooked up!
-
Going in!
-
Yay, it's in!
-
So when re you going to get to fire it up? It looks great. My wife wants me to paint my 6.2 similar to yours. I really cant argue with that.
-
the goal is tonight, I have to get some little things now to finish, like longer air cleaner stud, the kickdown stud for the throttle linkage, some hose, etc. and it will be ready to go, still gotta wire in the relay setup for the fans.
-
It is in, it is done, and WOW! Post pics soon!
-
Here's an ok video of it idling, i'll make another with it out of the garage!

-
Hard to hear with the quality of the audio, but you can definitely tell it's choppy. Glad to see you have it in and running. Have you taken it out for a rip yet?
-
Lookin Good! Good job man. Isn't it fun? lol Everyone thinks I'm a freak for having all of my trucks and projects rolling at the same time.
-
I've drove it but babied it for right now, definitely a difference in the sound, everything in the truck rumbles now, esp the back window. I gotta get the choke tweaked a little better on the carb and do some timing tweaking, it diesels on me a little. I'm gonna make a video and show off what I did to the motor, I had to buy new valve covers, the ones in the pictures were a crappy casting, and the rocker arms sat there and hit them. Truck sounds like it dropped a set now haha, The idle is soo awesome to hear, it gets to 60 with little effort now and doesnt run out of steam at 3500 like it did before!
-

The new motor is looking great. Good move going with the new valve covers. I have a set of vortecs that have GM aluminum valve covers for an 87-91 vette on them. The covers had to be ground down with a die grinder due to clearance issues with the rocker arms.
-
Great job bro! Sweet looking motor and must feel good to know you did it all yourself.
-
Looking NICE! If it goes like it shows, you're all set! ;D
-
I gotta get it in time, gotta recheck the timing gears...It runs like crap, it's all cam right now. It has a sputter at about 1100-1300rpm when accelerating, then it does okay. It doesnt really pull hard til 4500rpm. I think the truck is geared higher than I expected, if I put the brake in and floor it, the engine revs to 3100rpm but wont even spin the tires. The guy that did the valve set, seems like he did it too tight, and may have ruined my camshaft, but hopefully caught it before that. but if my cam is bad I'm goin with a summit 1103, It has the bark, but no bite til 4500rpm, if it was geared shorter, it'd be a hoss, but the old setup would blow my doors off til the current setup got into its rpm......
-
Sorry to hear that dude. Must be disappointing to do all that work on the build only to have it not run like you were hoping. :-\ Hopefully it'll shake itself out there. Wow, yours doesn't make power UNTIL 4500? Crazy. What do you shift at? Mine starts to drop off AT 4500 lol I looked up your cam though and it kinda doesn't surprise why you have the super soft bottom end:
Crane Energizer Cam & Lifters 3200-6200 RPM #100182 286/286 adv duration .462/.465 lift Valve Springs must be change, 2500+ stall, Not Computer Compatible
That's a fairly hairy cam you have for a rather heavy truck. What rear gears do you have? Lots of duration there for a somewhat modest valve lift. What's the LSA on it?
-
Why do you think the valves are too tight? Do you mean you suspect they were tightened to the point of making the lifters solid? Did you install the cam straight up? If so, try advancing it 4°. That is a fairly aggressive cam for the street, so it is definitely possible you over did it.
You don't know what gears you have?

If you manually shift it, after 4500 it slings you back in the seat. I am not 100% on my gear ratio, I just used a calculator online going 55 at 2200rpm in drive with a 30.7in tire on the back, it measured at about 3.67, so we ASSUMED 3.73 being a factory 6 cyl runnin gear too. But of course, speedo could be off, etc.

We suspected the valves were too tight almost to the point of being solid, one cyl we backed it off about 13 complete revolutions before it started to rattle, then we turned it a half turn and it quietened again., they need to be gone through again sadly. We've backfired through the carb like 5 or 6 times already, ugh... One of my friends thinks I got a dud carburetor, being an idiot, I think I did overcarb it being a 1411 750cfm on it. I did run a 750 edelbrock on a malibu with a crappier motor, and it ran fantastic! of course it was in time good. i wanna go through the valves without it running, I'm tired of oil slinging all over everything under the hood.
We got the cam degreed straight up, I'm worried it may be off a tooth or 2, its one of those double rollers with the option for -4, 0, and +4 settings.
It's really embarrassing not being able to do a burnout! ughhhh, i'd go back to stock idle sound if it would roast that dog leg rear end like it used to be able to do!
-
You could always try the method of jacking up the one rear tire, put the trans in neutral, mark the driveshaft and the tire, then count the tire revolutions for 1 rotation of the driveshaft.
So do you shift at 6000 or so? I haven't taken mine past 5500. I'm afraid to lol I'd say that carb is too big. The popular 1406 would be fine for your application. If you did have to replace the cam, I'd go a couple steps down on it so you have a more street friendly powerband but that's just my opinion. Mine is only a 268 duration but still has a nice chop at idle so you know something is different under the hood.
-
Oh I plan on stepping down on cams, the summit 1103 is probably gonna be my pick
.442/.465 214/224 on a 112 LSA. I heard it on youtube, and it had a good healthy chop to it, so I like it, and the powerband starts around 2000rpm
-
about how much was the machine work to your vortecs?
im thinkin of buying a set but i heard they need the valve guide machined to be able to handle any lift over ~470.
also which springs did you use?
and did you use the stock vortec rockers or older rockers?
-
Welp, my truck LIVES! Popped the timing cover off, and voila, it was 6 TEETH OUT. lined everything all up, and dropped the dizzy in, set the timing, and the truck runs like a dream, idles perfect, and runs like a pure champ! I actually have bottom end, and after 3500rpm instead of 5500 rpm it slings ya back in the seat! And I have good vacuum for my brakes and everything else No dieseling on 87 octane, just flick the keyswitch to start, when it shuts off, it's done! ;D ;D

They have a regular valve job, the valve guide bosses were grinded down for clearance, teflon seals, "z/28" style springs, and resurfacing. I used the stock self aligning rockers with them, I didn't pin the studs or go to screw in either. I know my lift is only .465 but I wanted to be safe.
-
So the cam timing was retarded by 6 cam sprocket teeth. :o How did that happen?
Glad you discovered and corrected that.
-
Believe it or not, it was "dot to dot" but something didn't look right, so we grabbed an old factory set, and lined it up off it and noticed how bad it was off, so we lined it up to the factory specs, and it runs now! So stay away from Zoom double roller timing sets.
-
Wow, that's crazy! Glad you figured it out though. So no cam swap no eh? Now take 'er to the track and let it rip! :)
-
Glad you got it running right. How did you degree in the cam and be that far off though?
-
Well stickin the cam in and timing set was one of the things I didn't do, I was busy with painting my firewall and all that while that was being done, I barely even saw the cam go in the motor, so I didnt notice. No cam swap now. It sounds sa-weeet. I've already got compliments on it just driving it today people roll their windows down just to tell me, I like that! I need a gear bad bad bad
-
Right on. So what is your redline that you shift at? I'm surprised the truck ran at all with that many teeth out.
-
well, when i just throw it in drive, it shifts round 3500 in 1-2, and 3000 2-3 and sits round 2100-2200 round 55-60. When I do the shifting, I shift round 4500-5000 since it can go that high so easlily now. It's so high geared if I go that high in rpm, I can usually cut 2nd gear out which kinda sucks.
-
Nice. That's how my TH350 likes to shift too if I let it shift itself. Modulator I guess needs adjusting. Sux when the fun is just starting and it upshifts lol And not having downshifts anywhere above 2000 RPM too is kinda lame.
-
I think you can adjust the governor to rev to the sky in full auto by changing out springs/weights. Have either of you guys checked your gov gear? I think it's pretty common for them to applecore over the years. My 700R4 behaves almost exactly the same way. I have been meaning to check my gov gear and if that looks OK, play with the springs.
-
Nope, haven't checked it. Trannies scare me :D I suppose I'll bust out the Haynes manual and check out what's involved with doing this. I'd really like to since it bothers me a lot how it behaves when I'm trying to have some fun. It would probably 'feel' faster too if it downshifted when I want it to. My 81 Jimmy 2wd 305 2bbl did the same thing. Wouldn't downshift unless WOT. But a 80 350 1/2 ton LWB I drove for a while downshifted beautifully. It was pretty low mileage though.

If Vile received a nickel for everytime he told someone to check their governor gear, he'd be a millionaire.

Great Looking setup 82',glad everything panned out for ya!!
