I want to get a good horsepower estimation on the setup I plan to get before I actually buy it to make sure it will do what I want. I'm planning on getting a holly stealth ram intake manifold, aluminum AFR 180 heads with the 64cc combustion chamber, hooker competition long tube 1 5/8" primaries to 3" collector headers, either 3" dual or 4" single exhaust with good flowing muffler(haven't decided which yet) and a good mid range cam to go with the power range of the heads and intake. I'm not very good with cam specs yet so if you would like give a few different ones with advantages of each thats fine. Of course I also will make the nessecary adjustments/upgrades to the fuel injectors, fuel pump, and computer to support these changes.

Basically, I aim to get good mid to high range power, say from 3000 - 5500 RPM while maintaining good drivability, idle, etc. So tell me, am I on the right track?

 

cubic inches- still 350?

Go bigger than AFR 180- use the 190's or 195's

I believe the exhaust is a little too big, especially if this is a NA set up (no nitrous or boost). A single 3" should be fine at most dual 2 1/2"

Probably keeping it at 350 ci for now. I know the exhaust is too big, but it doesn't hurt, just in case I supercharge or spray later on.

 

use 190 or 195 heads, and match it up with the right cam, you could easily achieve 400-450 crank HP...
