Optimum cam spec

What exactly do I need to look for in a cam, lift, duration, lobe seperation, and rpm. I am building a basic rebuild, stock or small converter, maybe a 20g in the future. I have an ultimate so I will have some range with the boost settings. I know it is a beaten and quite a generic q' but I am comparing the comp cams with the edelbrock 3714 cam. Also if anyone has any suggestions on different cams let me have it. Thanks.

Re: Optimum cam spec

you could look at the comp cams like the 412 415 and 422 that most people go with on the board that has been proven.

I'm happy with my comp 422 - I believe it is not specifically for a turbo, but it performs well for me.

Unless you are changing your cylinder heads, the 415 and 422 are a waste and the 412 may be pushing it depending on just how good your heads are (and I have not found a really good set yet). The stock heads don't flow for crap. Plain and simple. So a bigger cam will be choked by the limit of the heads. The stock cam is wimpy so moving up a bit will help but don't go too big.

Why not go to vortec's? You won't really spend to much more on them if you do it right.

Yeah I have 2.02/1.60 port and polished L-35's I will be using. I was looked at the comp cams and I know they have been used with sucess but was wondering what the magic #'s are, Like I said before, lobe seperation, duration, etc, what #'s work best together. I am somewhat familiar with cam lingo but the lobe seperation and duration are alittle confusing.

That obvioulsy makes a difference. One thing I noticed is that you mentioned about using an ultimate chip. Ultimate chip work best with stock cams/stock heads. Because we use a map base fueling, once you start changing the air flow through the heads or allow more air into the heads because of large cam lifts or longer durations, the fueling tables will change.

I have a bullet racing cam 215/215 .488/.488 114+4 laying on the shelf. Idled great at 675rpm. Had power everywhere and was really a nice cam all around. At the time I wanted to go just a little different than the comp cam grinds but enjoyed this cam when the truck was finally tuned in.

No matter what your going to be way beyond a chip and should be looking into tuning the truck yourself or hooking up with a tuner to help you out

I just responded to your ad in the for sale section about that cam. Yeah I know tuning will be vital once it's done.
