Hey guys i wanted to know what kind of hp and torque numbers i will see from my new engine. It is a mexican blocked 347 with all forged internals, with patriot perfomance 185cc heads with 11.1 comp, eblebrock cam .524 lift on intake and exhaust with 1.6rr, edlebrock performer rpm 2 intake, 70mm tb, 75mm maf, 24lbs injectors,and cai. I think that is all so i wanted to see what you guys think it would make just at the motor or if any thing will help out at all i am hoping for some good numbers. thanks
70mm TB seems a little small, as does the 24lbs injectors & the MAF. Are you building this or buying it complete?
The t-body will be fine. The mass air should be bigger tho. 30# min. inj. Without knowing dick about the cam. I would put you in the 400-425hp range.

Your flow and power numbers will most likely be lower. The intake you chose is in between the systemax and gt-40 so I will show both numbers.Only thing changed was intakes.
