Hi, Never asked for help yet, but I need it now!
I rebuilding a stock 67 Sport Fury 383 4 speed hardtop
Had motor machined .030 over bore, 010 on rods and mains.
I prefer more lowend giddyup than highend.
Since it's a 4 speed, with manual brakes AND steering, not concerned with vacuum or idle.
I want to put a 291 291 .509 cam in with stock 516 heads. The Summit kit I was gonna get has Forged flat tops
which they say gives me @ 8.94 compression. i would like at least 9.5-1, or 10.0-1 compression without breaking pistons or valve heads!
Does anyone know if this combo will work? tried it?
Heads are stock 88cc.
Also, could I or should I change from 1.5 to 1.6 rocker ratio?
I am hoping someone has already plowed this issue and could give me any ideas on what works and what don't work.
Thanks in advance for any advice!
