I need my 302 to get to 7k rpm, because I have 4.86 gears. The car (a 67 coupe) was a dragster and I like the gears like that. It has a C4, 9" detroit locker, 3500 B&M super hole shot conv, B&M strip shift kit. The original 289 was blown so my dad had someone put a 302 out of a 83-87 Fairlane in it. I'm working on the carborator after reading a ton. I took off the intake manifold and found the wrong gasket(half blocking 1 coolant passage on each side). I probably will not do a rebuild for a while, but I've been reading on that too a little and thought I could use some advise. I also like the carb (holley 4010) and manifold (holley contender), but it's a dual plane and I've read they are not good for high rpm. 302 w/600 cfm carb at 100% VE should get me close to 7k. The heads are 289 6k11 and something and are suposedly hot. 1.5" headers w/dual exaust should allow good breathing. I want to keep it under the hood (our little secret). I think it has stainless steel valves and crowler roller rockers too. In the trunk I have the old blower, intake manifold, pistons, and cam. I've read that light recipocating parts (piston, rods, and pins), and high compression is important. Plus strength. Now I'm finding I might need a better (balance) crank and lifters or something to handle the higher rpm. So, will this carb-manifold do? Cam 2800-6200 or 3200-6800ish RPM? I know I'm a noob but your thoughts would be appreciated.
