Motor has 16cc dish pistons, 64cc stage 3patriot heads, .052 gasket. Plugged numbers into CR calculator and got 10.06:1 compression. I had originally planned this motor to be a 370 but things changed and now I may not have enough cam. Cam is as follows

Comp 228 230 cam with .571 .573 lift and 112 lsa. The heads are also coming with harland sharp 1.8 NA rockers which can put me to .604 lift if I decide to keep them instead of stock 1.7s. I read that using a smaller cam will make excellent torque and that is what I want but I also want it to pull up to about 6200 rpm.

What rockers should I use and why? Will cam do pretty good or should I go bigger? If so how big?

 

personally i think that is to small of a cam....i ran a larger on in a 6.0, hell thats a slighty larger then mild cam for a 5.7 rather alone a 6.6

 

The Wood Hauler has a 233/239 in his 408 w/ a Victor Jr., could be bigger but it makes great power all over the power range, shifts around 6500. I would try to use the Harland Sharp rockers if you have them.

 

Well you will not ever exceed your flow limit with those heads so to say. 228/230 is what im probably going to run in my 6.0 and expect it to have a good bit of low end. That in a 402 extended cab with 3000 yank should be nice.

If I were you and were serious about changing camshafts and can afford/or have the springs to handle it. Get a cam on LSK lobes. People compare those to XER. They run less duration with the LSK lobe but yet pick up hp and torque all the way to 6200 where then it still doesnt fall off with the smaller duration cam with LSK lobe just maybe 5hp PEAK less. But pick up 10-15 hp and ftlb of torque up untill peak torque.

You need to remember you manifold(truck manifold) is a killer in this setup. If you seriously plan to keep it you mgiht want to inform someone helping you pick a cam. Their is a great post going on over at tech about restrictive parts of the motor(i.e. intake, heads, or exhaust) and which split/duration cams work better for which. In your case your heads are the best flowing. And your intake is the worse.
Do you plan to keep the truck intake?

 

Quick your also lighter and had a considerable bit bigger stall!

 

I just saw where you are planning ot keep the truck manifold. If you plan to keep that and dont mind changing cams later on down the road. Just sliding in a cam isnt that bad. You may want to look into a reverse split like the TR 230/224. It makes much more torque under hte curve when the manifold is the most restrictive part. Then later when/if you change to ls6, fast, vic jr, etc. you can change cams.

 

didnt look close at the pic to see he is extended cab or read and yes i did have a stall that was stalling aroudn 3800

 

I think it'll be a good cam. But, I'm running a 383 with a slightly bigger cam on a stock stall! It's plenty cam for me, but if I had a 402 I'd go with something a little bit bigger. Especially since you have a 3000 stall. Something like a 236/240. Also, you'll want to get rid of the truck intake. Your heads are gonna outflow the intake big time. The truck intake is what's hurting my set-up. Pulls great until 5500 then at 5700 goes flat all the way to 6400.

 

i just did a 244/248 612/615 112+2 in my 408...you can go similar

 

I'll probably go with a bigger cam once I swap out the intake. Truck intake is going to be a big restriction but I wan't to get the new engine in the truck before I spend more money.
