Clois,
I am contemplating either 3.27, or 3.08 rear end on 26.5" tires, that will give me 6500rpm at 165mph. That sort of speed is not really important as it will be used on the track at a max of 150mph.
Cruising speed of around 65mph at 2500 with the 3.08, 3.27 = 60mph, sounds like if you want a goer at the top end like pulling hard at 6500 it wont like cruising much under 3000!
I have no idea what I need as I haven't really studied 427 parts, but I will be using roughly as below,
427 Alloy block
Armandos racing
oil pan
Edelbrock Heads
10.1 comp
Edelbrock Victor single plane manifold
I have no idea on internals but would run quality forged parts, probably phone KC and ask him to supply parts and of maybe build it for me pending $$$$$
I saw a Gessford video on a blue 472 Cobra with single plane manifold etc, and I gotta admit it it didn't sound brilliant with the exhaust it had, or maybe they are big lumberers. If you can fit some sort of balance pipe to these cars it would make a difference!
