Re: Low rpm 390 stroker advice
I had a 67 galaxy 500 with a 390 that I built some 40 years ago. bought a balanced rotating assembly stock stroke .030 over with forged pistons rods were shot peened with good bolts. ran a crane hydraulic 525lift smooth idle cam with a stock valve train except for springs and retainers it was a cam kit. Holley street dominator intake and a 780 Holley 4150. stock heads and valves with a good valve job. Mallory dual point mechanical advance, MSD 6, and Accell yellow coil. Did have Hooker headers but never did have an exhaust system better than 2 1/4 dual. had a C6 and a 325 open rear gear. It wasn't a drag car but would chirp the tires at 70 mph for the 1-2 shift and at 110 mph for the 2-3 shift. The only parts I ever broke were a couple of rocker shafts and broke the centers out of a couple of flex plates. I still have the motor and trans the galaxy succumbed to rust and had to be retired. building a 69 mustang with a Fe that engine was bullet proof.
