400 RWHP easily...I highly doubt that. My combo with AFR 185's was only 15 RWHP more than the 165's I have now. I kept the 165's becuase I like the way the car felt more, probably due to the higher compression.

Put on a set of A.F.R. 185's, Comp XE-274 or XE- 282 H.R., Systemmax intake, 75 TB, 30LB Injectors and a 75-80 Mass Air Meter. Should pull over 400 h.p. to the rear tire easily. With all the parts you originally listed maybe 310 at the wheels and that would be stretching it.

could always build a conservative motor with strong internals and just spray 100shot on it, monster when you want, docile all the rest of the time....

the heads, cam and TB you have choosen will choke the
**** out of that engine.

Will serioulsy limit your top end power.

you could get 275rwhp with those parts on 302

get a cam with more durration
get a bigger TB - 70-75mm
get a bigger MAF 76mm min

331 will overload 19's and still push 24's to their limit.

With the right heads,cam and intake a 331 can put down 325+rwhp

AFR 185's would be better if you can afford them
and TFS stg2 cam or CompCams XFI stroker cam
the extra displacement needs a cam that opens soon and closes
later to give it time to fill those extra cubes with the air it wants.

It may choke the engine at high RPM but this is a street engine so it should be strong in the lower range, which I think will..

1) high durration cams are only good when you bump the compression ratio with a stock CR (or near stock) the piston won't have enough time to build pressure and loose a lot of power in the low end which isn't good for the street...
2) 65mm TB is enough imo...
