Hey 18436572, this guy gave me the same idea over at fullthrottlev6 who has built some 350's. He said go with Vortec 64cc heads I believe. I think that the cam he mentioned is an xr264 which is rated Lift .487/.495 and doing a dual plane intake with 750 carb. The 64cc vortec heads I found are good to up to like .500 lift on summit racing. Thanks for the ideas for the tranny. Not sure what headers I'm going to use. Noticed some are 1 1/2 n other are 1/58" so not sure which way to go. Doing long tube headers and dual exhaust. Checking out the style muffler I want right now. I don't want anything single chamber that's gonna just scream. May go with something by magnaflow or flowmaster hushpower mufflers, still not sure. I want to be able to drive it and actually carry a conversation with people riding with me lol
