stock rear is 3.55

the stock engine is getting close to 70k miles. I will probably getting on
it a
lot after its done, so i would prefer a full build. I may also do forced
induction in the future. I really dont trust the stock internals, especially
the racket the engine makes after 4k rpms (it sounds like its gonna come
apart)

Bernds V6 was somewhere around 260hp flywheel? or did he get it higher than
that? but he was supercharged, wasnt he?

as for intake manifolds, i found this on hughes website, but theres no talk
on
the dml about it.

can anyone comment on it?
