I was wondering if I could get a Guesstimate on a combo I am building. Here's what I have....

74 455 bored .030 over
standard crank
Lunati Bracket master II cam - 292/230 .490 110sep
Performer intake
1 5/8 headers
holley 750 vac sec
HEI ignition
compression ratio between 9.5:1 and 10:1
I haven't decided on the 6X-4, 96, 66, 5C or 15 heads, suggestions?

Any help would be greatly appreciated!
