What cubic inch?? Using stock grey cast caps may not be the hot set up and a sonic test is a must if your using an OEM block.Can stock gm 4bolt main small block be used for 9-1 pro charger build
Looking doing a 427 i have the. Block laying around but dont want to do it twice so may wait i have a 383 in car now with afr heads forged bottom end 10,5-1 is that to much compretion for a pro charger i have caught the procharger bug love the sound
Very nice!!!!!!!!!!!!!!!!D1? You should make 600-700 RWHP with little effort. If you would be happy with those numbers, I would feel fairly comfortable with that block. The problem is, no one is usually satisfied with what they have. If you try to push it, like most everyone does, something is gonna give.:yes:
My 64' with a 406 SBC with AFR 210 heads and hyd roller cam made 698 RWHP at 18 lbs of boost. No intercooler, with A/C.
