Just got a short question for you all, before I tear down and start the rebuild. I have a 68 429 thunderjet that needs to have the crank redone, so im going to go all through it and hopp it up alot. Before I really get started I wanted to know if anyone knew what the CC of the cyl. heads would be. They are original 68 C8VE-E heads. If you also know what is the valve size and whats the biggest size I can go up too. I have already started to get some things for the engine. 4 bolt caps, All the ARP bolts made for it, Intake, Carb and Cam. I dont have the actuall specs of the cam infront of me but I will find it and post later. Maybe a suggestion on other combos I didn't think of. So you do Know the engine has never been apart, other then a timing set being put in, and it is a factory 4bbl.
