i've got a '91 stock bottom end,E-303 cam,performer rpm air gap intake,1.7 ratio SVO roller rockers,mac equal length headers,msd 6-A and blaster 3 coil,underdrive pulleys,H-pipe,and a holley 650 double pumper carb.could anybody give me an estimate on hp?
My heads are ported/milled and are worth ~20rwhp more than the stock unported heads.
I have a 76mm MAF, 75mm TB, and a Performer intake that's been port-matched for the 75mm TB, so it should flow a lot more than 650cfm.
My headers are long tubes (more power than shorties) and I don't have cats.
Your E-cam will only produce slightly more HP than the stock cam when paired with the stock heads, and it'll produce less torque below ~3000rpm.
