350 w/ Holley 2bbl
TH350
NP203
As of right now, the mods are:
Headers
Dual exhaust (with H pipe)
Two glasspacks and turndowns
6" Rough Country lift
Autogage 8k RPM tach
Autogage oil pressure gauge
Autogage temp gauge
American Racing wheels (AR62 Outlaw II 15x7) with 32" Regul A/T tires
Two Hella lights up front
Issues:
A 2 barrel, really? (With which I'm somehow getting about 5mpg at the moment, might I add)
Fuel gauge stuck at Full (ground?)
No radio
Sticky windows
So really just little stuff for issues!
Has seats from an unknown newer vehicle, gonna see if I can get the seats from my '95 Sierra to fit with a bracket modification.
Not really sure what my plans are for now. First thing is removing the mud flaps, adding manual locking front hubs (all time 4WD ewww), possibly do the Mile Marker transfer case mod sometime as well. Fix the little stuff and then I'm thinking of swapping a 5.3/4L60E or build the carb'd 350 and get a pro built 700R4....all in time though.
On my way home I stopped at a gas station (of course) and started talking to a guy with an El Camino. He had an Edelbrock EPS 2701 intake sitting in the back so I asked him about it and he sold it to me for $20. Says it may have a crack in a coolant passage, I'm gonna look into it but I cleaned it up and it looks nice!

Welcome from Northern Illinois. Nice find, good price.

About 5 mpgs that's not right might need a tune up but something that's not lifted and running 38s should see at least 10. The 88-98 seats are about 6" shorter than ours so 3" smaller on each side you will notice it

Fine truck! Enjoy! 8)

Yeah I didn't think a two barrel would run rich enough for 5mpg. Do you think adjusting the idle screws could fix the rich issue? It idles at around 900-1000 which seems high for an old carb truck. Usually around 650 or 700 right?
-
Proper adjustment will help, timing is crucial as well. A 2bbl can actually help in mpg if you have a heavy foot but the drag of big tires and the aerodynamics of a brick is all going against you...
-
Hahah zieg85 that was great bricks are slick man haha my 80 c10 is having timing / mpg issues to
-
Which do you guys think would be the all around best option?
5.3, some bolt on mods, possibly something big in the future
Performabuilt 4L60E
35's on 15x12 wheels
4.11's
or
Mild build 383 Stroker (cam, springs, rockers, headers, etc.)
Built 700R4
35's on 15x12 wheels
4.11's
Also, what do you guys think of these LED headlights? I think the red would look pretty mean at night!

can you do a stick? granted you lose the od and between the 4l60e and 700r4 i would go with the 4l60e just because its computer controlled and they tend to be a little tougher imo.
my 79 with 6"+3" of lift and 38x16x16 was getting 8mpgs or so switch to 37.5x12.5x16.5 and it got 10
-
Yeah I could definitely swap it but I'd do an nv4500 if I could swap it so I can keep the overdrive
-
Well I got rid of the mud flaps, it looks way better I think!

Nice. Much better with no flaps.
-
Looked better with the mud flaps and at least they were functional. People driving around in lifted trucks without mud flaps should be beat with them. :P
-
People with lifted trucks should be beaten regardless lol.
Big rims, tiny tires, useless for anything practical.
Trucks like Mudder96 here are still use full and practical. There's a big difference between lifted 4x4 and use able 4x4.

I'm not saying there isn't. What I'm saying is people lift up their trucks but don't take into account what it does behind them. No mud flaps equals rock and debris tossed much easier at vehicles behind them.
Be courtesy to the drivers behind you and put mud flaps on. If you don't like them get some transparent ones.
-
Yea your right. Here in CA, they take clear pieces of plexiglass and cut them down to the smallest legal size and then mount them with these big over sized brackets that are painted to match the truck. Looks ridiculous and doesn't even really work, the tires are almost always bigger than the mud flap. You get debris tossed under and over them, there are only about the size of a 8x11 piece of paper, might as well not have any at all.
-
That's a really nice looking truck, and great price!

So I picked up a little something for Big Red last night... Got a 400sbc with 882 heads from a 76 K5 Blazer. I'm gonna clean it up nice and possibly build it up a little with a cam kit and maybe port and polish on the heads... Open to ideas! What size carb? 750cfm Eddy?
-
882 heads are junk heads and not really worth doing much to. Just your run of the mill era style heads. Although if they are the heavy casting they'll be better than the light casting.

So what would be a good replacement to get? Factory or aftermarket, budget build
-
That is not an original Minnesota truck is it?
May want to keep the mud flaps for winter driving. The mud flaps seem to delay the formation of rust because they help deflect the salt bath on the winter roads.
If there was ever a weakness to the '73~80 GM trucks it was a total lack of rust proofing.
