to respond to some thoughts,,,,
the exhaust was my first issue, used an Iceman crossover and 2-1/2 pipe with mufflers, this is still too loud for my taste but exhaust should not be the problem,
Carb is a Holley Avenger tuned by local carb wizard, Divinci, sitting on an Edelbrock manifold (suggested by Jegs. Most likely not the carb.
No idea what rear gears this car has. Is there a simple method to confirm? Then what?
Again, I don't know the power curve on this engine but it seems like it doesn't see enough RPM to light up the tires. "Aggressive cam" is mentioned in the start up & specifications. But I don't know if this engine has ever even seen 2500 RPM in first or second gear!
Because we disconnected the computer, a transmission lock-up kit was obtained from Jegs and installed when the engine went in. Maybe I am ignorant, but I thought a higher stall speed torque converter would allow the engine to rev to a higher rpm to attain horsepower. If my torque converter is locking up at a low 1300 or 1500 rpm, doesn't this engage the drive train to begin to move the car? Would a higher stall speed allow the engine to attain more horsepower and accelerate faster?
Maybe I just don't know..... Can you educate me?
