Hey guys new to Pontiac I have a 70 gto and a 72 gto I got a motor built for my 70 and it’s not powerful enough for me it’s a 455 10.5:1:1 compression icon forged pistons has eagle rods, wenzler aluminum heads, comp cams extreme cam Hydraulic Flat Tappet - Lift 0.488 / 0.491 in - Duration 274 / 286 - 110, crower enduro stainless roller rockers.COMP Cams Dual Valve Springs O.D.: 1.430 in. Edlebrock torker2 intake manifold port matched to a reworked 950cfm Holley carb. Hooker headers. I’ll try to but build sheet below a few parts a missing that I pre purchased before build. The reason I had to build it was because there was a knock that was supposed to be because the rockers the previous owner bought were hitting the valve cover and needed high rise valve coveres. Turns out Somone dropped a washer in the intake and ended up in a cylinder. there was also 4K in machine shop work so in total $10800 and I don’t wanna blow it up but made under 500hp and made good torque off the converter but around 480 not off converter
Thankyou for any advice
