Alright, havnt been on in awhile(been trying to get some money for rebuild and racing) my rebuild plan has been revised a little bit, as of getting my pay check this week im going to order a 625 Road Demon Carb, and all the stuff to rebuild my rearend and its posi. Iv found someone that will rebuild the tranny for me if i supply the parts +2kRPm Stall, so the motor is the only thing left to figure out. My plan as of current is to use a 625 carb for Daily Driving(Holly 780 Double Pumper for track) use the repo 428 4v intake and the repo 428 CJ exhaust manifolds with 2 1/2 or 3" piping after manifolds with edelbrock/spintech mufflers(anyone know which sounds better), now heres my question what cam should i use and what to do to the heads, my goal is between 350-400 HP with roughly 6kRPM redline. (utilizing HV oil pump and baffle/windage tray in stock pan) so iv heard that the stock 390GT camm is fairly good so its down to crane powermax/stock 390GT/Edelbrock Performer. For the heads i was just planning on a "street" port and polish(cleaned up bowl and chambers?), valve job, hardened seats, SO anyones advice appreciated its starting to come down to ordering parts and i wanna do this right the first time, motors a little hard to work on in that engine baythanks guys
