Hello All! I could use some good info on building up my 390. I do know it's bored .030-not sure on pistons, with some light port work done on the stock heads. Comp cam #HE268 218/494 with an rpm manifold, holley #3310 750, hooker headers, msd mechanical dist, mallory hyfire igntion, etc. Engine has 9:5.1 compression. Not sure on hp or tq, but would like to spend around $3500-4000 into it to get her to wake up more. Any suggestions? Thanks
