450 - 500 hp 302, all motor

[slow87GT]

the eeciv upgrade is the fms rpm extender to go past 6250 fact. rev limit

thinking your gonna make anywhere these numbers w/box stock cobra intake and shortie headers is plain crazy.

the numbers you want will require-
11:1 compression
heads capable of flowing 300/220 or preferably more, 1.94 valve is fine
1 3/4 longtubes
holley intake(or tfs but holley better choice)
the 282xe'll get ya there as will tfs stage 3 cam
solid roller, A4block, stud girdle, box intake, and 12.5-13.5:1 comp and 7500rpm shifts are what it'll take to break 500hp

be realistic, a GT40 crate motor will never make these numbers if god cams it, and w/3.27 gears, you just have know idea of what it takes to be 11secquick at the strip

be realistic, optimism is good, but there ain't a gasket kit worth 100hp
