philzamatic3100,
how radical is your roller cam ? whats the lift ?
do you have underdriven pulleys ? some guys put the underdriven pulleys to gain a few horsepower, but dont realized their accessories, alternator, waterpump, are now turning slower.
i have had a few cars years ago that had radical cams, loose torque convertors, and they did not like the street at all. always would get to 220-240 while setting in traffic.
