I'm having a 350 rebuilt, and I need to order a cam for it. I want one that won't mess anything up, such as robbing my vacuum.
The motor is from an '88 truck I believe, and it's being bored .040 over, if that makes a difference. I want good performance in the mid-range, but I don't want to wander far from stock, to avoid problems. By the way, it's going to be TBI.
I appreciate any help. :)

well you'll have to be a bit more specific on your set up. What trans do you have? Is this carbureted? What intake? Exhaust? What's your final drive ratio? What is being done to the engine?
If you are just looking for mild improvements over stock without drastically changing anything from stock here ya go:

Shouldn't he also install stiffer valvesprings with that cam or will the stockers do OK?

Like I said, it's TBI. Sorry, I didn't think the tranny mattered. It's a 700R4. I guess I just want something that I won't have to buy new springs for and I want it to be the biggest possible without messing up vacuum, etc...
-
Use the cam I recommended then.
-
ok dont get one of those crapy summit cams there junk! i have ran just about every cam out there and i alway run back to my boys at comp cams! if you want a lot of tork and hp go with comp cams 688h you get real good power from 1500 to about 6500 and you can still run power brakes and did i tell you it has a choppy ideal! and you dont suck gas down like crazy to

Summit cams are far from junk. We've used so many of those cams over the years and every single one of them has degreed in dead nuts and worked perfectly not to mention they are priced nicely. Some of the worst cam failures and poor quality manufacturing jobs I've dealt with have come from and in this order Edelbrock, Comp Cams & trickflow. I wouldn't hesitate to use that Summit cam at all.
-
No offense, but I'm going to take Vile's advice.
I can tell that he's been around the block from reading around here.
Thanks Vile, but one more question. Will I need one that is computer compatible or whatever it's called?
-
The cam Vile is recommending is computer compatible. TBI has been streched to run on bigger cams but a nice little RV cam like this is always a safe bet.

summit cams are ok and super cheap yes but y not spend a lil bit more and get a good named brand part........if you ask me you would sound pretty okie if you told me you were runnin a summit $55 cam...................put hey if you dont like it wont summit take it back??
-
I have to agree on the Comp cam failure. I had a number of them go bad and won't go back. Currently I use Crane, haven't had a problem yet. The last one was a used solid that I ran for 8 years.
Name brand has nothing to do with it unless you think throwing around company names is impressive. Summit is reboxing the cams they are selling AFAIK.
-
o really? well iv ran a crane 272 and i had 2 lopes go flat.............your right on one thing tho summit cams are just reboxed Lunati cams. well thats what my friend told me that works at summit! but he told me not to run there lifters
-
Summit had one batch of bad lifters and recalled all of them and shipped everyone who bought them a free set. I still have the set because we never had a failure with any of them. Edelbrock flat out told me they do NOT make their camshafts.
-
Does Edelbrock make anything any more except boxes with their name on it?
-
I tried to order a performer rpm air gap oval porrt with polished finish and waited months and finally cancelled the order. Why? Because they were still waiting for them to come in. lol So much for that made in USA sticker they were putting on their manifolds.
-
You obviously misunderstood, Vile. The sticker is made in the USA, the manifold is cast with pride in China. :D
-
and obviously polished in Yemen

;D :D ;D :D ;D that is hillarious!! ;D :D ;D :D

Well I figured I bought a quality cam and lifter set with my CompCams Xtreme 268 and will still feel like that.....unless something goes wrong lol Nothing against Summitt either. It's an incredible value and Summitt wouldn't want their own name dragged down by bad product. Probably the biggest favor you can do for yourself is using a good oil with higher levels of ZDDP (or zinc for short) for long lobe life. Roller cams have no worry, but popular modern car oils are not helpful to hydraulic or solid tappet life. Do a search for "oil" on here. There's a couple threads about it.
