360 Build ... another one

3.5's as in 3.55 gears?

On what size tire?
Is there a converter change in the future or possible?

Is this powr possible. (OMG! YES!!!!!!!!!!!!!! And why not?

IMO, and how I like to do things;

Zero deck piston height (KB 107's or Federal Mougal cp116's, deck height may need to be milled down to make it a zero deck height.)
A cam like or similar to a Comp Cam 280 (230 @ 050)
pocket ported heads
RPM intake
750 carb headers (Extractors)
2-1/2 inch exhaust pipe.

400+ no problem.
