Shaker455
I wonder if you could run the numbers on the 455 I am now building for my 67 firebird
Balanced stock rotating assembly
211/177 heads that flow @ 265/215 @ .500 lift
SRP pistons approx. 9.5/1 comp.
Comp hydraulic roller ground to 230/236
1.5 full roller rockers
Edlebrock Performer RPM
Speed Demon 850cfm annular carb
Have not got headers yet but will be 1.75 4 tube type with either 2.5" or perferably 3" x-pipe exhaust any recomendations on headers for a first gen bird?
