How much power?

MyHoFoSho said:

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.

TEST 1 -- GT-40 Intake-Baseline
•Peak Power Numbers: GT-40 Intake CHP 347-AFR heads & XE292R cam
•Peak Horsepower-GT-40 450 hp @ 6600 rpm
•Peak Torque-GT-40 447 lbs.-ft. @ 4700 rpm

The heads you are useing are AFR185 knock offs. so this comparison should be close. 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.
