Thread: Anyone running 487 Heads

Tweet

I rebuilt a set of them . 1971-72 350 Heads 74cc chambers . I installed all new S/S valves and Z/28 Springs with Performance Retainers and Locks . With .015" shim Head Gaskets and Flat Top Pistons you should be right about 9.1 C/R . 300 H.P not a Problem I would say by the way the Ports Looked they are about the Best 74-76cc Smog Heads and not a thin casting . With a Good Dual Plane intake 450"-460" Lift 216-218 at .050 dur 110 L/C Camshaft and a Set of Headers it will be near 350 H.P and run on Low octane Fuel every day trouble free .

Thanks Tango. That sounds great and easily do-able on a small budget.

Tango,
Did you go with the S/S valves and z28 springs because you needed them for the lift or did you just wanted to replace what you had? Basically, I'm wondering if I can use my stock valves and springs with the 460 cam. I don't know what the max lift is for 487 stock heads.
