Re: 351C... CHI heads?? Funnelweb??
Nothing has really been done to my 4V's port-wise.
Screw in studs, guide plates, Ferrera valves, Jomar stud girdle, 1.73 roller tips, comp springs to match cam, Ti retainers, 10* locks
Ports and combustion chambers are untouched.
385 ci Cleveland. 10.95 @ 127 mph. Street tires and mufflers.
