My requirements... what to build?

Magnum
or late 360 roller block
deck heights are different so all the pieces stack up differently
head cc's vary all over the place too as do pistons

"at the beginning you mentioned the 360 paired with the A998. Then at the end in the recap you mentioned using the 904. So whats the real thoughts?"
I'd wager aj is using the 904 as a generic term for an a998/a999
let's see what he says he just postd after I wrote this
Me i'd use the a999 with a taller rear gear and a wide flat powerband
Testdrive a dodge dakota with a 318 or 360 magum and lock out the od
how's it drive
enouhg power for you?
what else do you need
then try with the od to simulate a tall geared 3 speed TF
how'd that work?
how did hitting passing gear feel?
don't feel bd I have to read aj,s posts over also
well worth it and food for thought
