i have 383 , I got 195 comp port AFR heads, comp 306 cam, ported lt4 manifold, hooker long tubes, etc etc.
this car has been sitting for a while and i have decided to go full drag car, but on a budget, i was wondering can go with a big solid roller cam, and still keep those heads and make decent power??, or do i need to change heads to make decent power? also if i go solid,what lifters pushrods and springs are the most popular, and how big of a cam should i go with, until i am reaching a point where i am not making that much more power.

 

anyone??

 

i would say go with bigger heads man i have the same heads on my 396 LT4 and they are whats holding me back, and with a solid roller you will have even more air going in and out thsoe heads.

 

yeah i am kinda on a budget, but which heads would you suggest??

 

then i would say to use the heads you got just get some who knows what there doing to do a nice port job on them, but if you could get new ones then i would go with the AFR 210's, or the LE3 heads.

 

i know here you could get a set of brand new LT4 AFR 210 competition port heads with port matched LT4 intake ready to bolt on if you're interested in that route.

 

well how much power will a 210 yield me over the 195's, i already have a lt4 manifold so i dont need that, i was looking into 227's??, or they not really a option

 

Ryne, be careful where you get your information. Your AFR 195 castings are the same as the AFR 210 castings. The 210s just have more work to them.

I prefer the 210s over the 227s. If I were in your position right now, I would just have a little more work done to your heads, flow them, then give those numbers to Cam Motions and have them grind you a solid roller. With good tuning, your car will fly.

My solid roller 396 w/AFR 195s ported to ~211cc was trapping 126mph with a fairly small cam. That was before dyno tuning and running 17" rims on all 4 corners.

Sent you a PM as well.

Welcome Back....to The Lt1 Section!!!!! Lol....

 

you should be fine, here is my cam specs, 264/270 @ .050" .631" lift w/110LSA
this is a huge solid roller and i only use a set of ported RGR stage II heads, these are LT1 cast heads, not LT4. i went 10.98 @125 with a super tight nitrous converter on horsepower only, no spay let. your AFRs flow more then these LT1 cast heads do.

 

thanks alot guys, i am going to look into more headwork, or possibly just going with a big solid roller, lots of decisions lol.
