I have my 289 at a machine shop. It's the original 289 from my 68 with a 302 block. Should i keep it a 289 with 54cc early 289 heads( not the original heads the car came with) and 9.0 to 1 compression. Or, for a couple hundred dollars more put a 302 crank and rods in it with a comp ratio of 9.5 to 1?
Will the performance gain, if any, be worth the $250 for a 302 crank and rods? I will be using a mild cam with about a .212 duration at .050, stock C4 converter and 3.50 gears.
Thanks Guys!
