Questions about Cobra Jet 5.0

[201250]

NHRA tech has told me that in general they will accept a replacement piston that is slightly less compression BUT that it must be submitted as an offical replacement piston. A racer or engine builder can submit a stock 5.0L or 3v piston, or an Aluminator piston as a replacement for the Cobra Jet piston and ask for it to be approved.

I didn't know we could do that. WOW Can I send one of the Manley rods and have it approved also. Kdanner is right can I use the 6r80 trans as approved along with a beefed up 8.8 instead of the 9"?
