Performance rebuild

I was wondering if there is a particular reason for me to run a high volume oil pump in a freshly rebuilt motor. I've been told good idea, and it doesn't matter. The motor is 350 going into a '93 K1500, used for DD, towing, off-roading, work, just the usual stuff. It would be bored 0.030 over. Also, any recommendations for for cams and intakes? Or if I should do a cam first and then intake? Or Vice-a-Versa? I was thinking Edelbrock intake and possibly cam, or a comp cam. Any info or recomandations on either or others? If you've got any other info, feel free to express it. Thanks all.

Re: Performance rebuild

well, if you've got it apart and are building it, do the cam first...you have it all apart. later on its plenty easy enough to swap an intake out. much harder to do the cam later. when considering the cam, I'm not the best guy to go for looking to get answers. i talked with the guy at the engine shop and told him what i was planning to do with it and what i wanted out of it. they deal with it everyday...i dont. some of the guys on here know cams pretty well.

Re: Performance rebuild

I don't know alot about cams, but I do know that if you get real crazy with the cam (as far as an rpm range goes) you'll lose vaccuum and low end performance. I personally would do the cam up front while the engine is apart. No sense in kicking yourself in the ass later for not doing it. You may find that under 6000 rpm or so you don't need another intake. Whatever you do you, you'll have to remap your EFI as well. That may be another cost determining factor. I think it's better to have it and not need it than need it and not have it though! Ihope it works out!

Re: Performance rebuild

Are you using the stock TBI set up? Most people like the Edelbrock #3704 TBI intake. Also a lot of people use Crane Cams POWERMAX 2030 camshaft. Do the camshaft first, much easier with the engine out. Also, don't use a high volume oil pump unless you are using a larger oil pan with more capacity, a high volume oil pump will suck the regular sized pan dry, especially if your oil ever gets a little low.

Re: Performance rebuild

Yeah, I am using the stock intake, but I have decided to get the stock heads, ported and polished, and getting a cam. A buddy of mine and myself are just finishing a rebuild for a motor that blew in a van. The one that came out of it has practically brand new pistons, and I've still got a running block that we're going to tear apart. I figured around $500 or so for the rest of the build.

Re: Performance rebuild

If you can afford it go with the Vortec heads and Edelbrock intake, you will not be sorry. For the money to get your stock heads to flow like the Vortec's you will have more money into them. Also look for a cam in the .440-.460 range with 206-212 duration @ .050 lift. This will give you great low end torque, and flow velocity for the heads. And don't forget the headers. Have you ever used an engine dyno program for your computer. (Dyno 2000) it will let you change components and graph out the changes every 250 rpm.
Well worth the 40$.

Re: Performance rebuild

I asked the guy at the machine shop, and he suggested going with and older stlye head ['80's era], he said that they will flow much better, and work better with a cam and after-market intake. Talked to several others, and they seem to agree on that too. I'm going to look into it a little more, but that's sounding like a good idea to me.

Re: Performance rebuild

L98 heads off of a TPI camero or firebird 350 will flow much better than stock and bolt right up to a regular intake with out having to plumb the egr or buy and expensive tbi-vortec intake.
