The throttle cable is easy enough to figure out by just have a friend floor the gas and look down the throttle bores.

Motors in the 600 - 700 hp range are fun, but not a monster. Zero to about 130 mph is kind of fast like around 12 seconds and then the air barrier slows the rate of exceleration.

The side pipes are likely killing 40-50hp....atleast...

That car should be down right nasty.....I think you have some stuff on that car that is killing the motor..,,

Yeah that muncie is on borrowed time....I would be looking at a TKO600 or Magnum t56 soon.... Or better yet, a t400....
