We put an AVS Thunder 800, on a close to stock 440 (headers, 2.5 inch duals w/ crossover, performer intake, carter fuel pump, chrome ecu, large k&n air filter, made minor adjustments, and haven't touched it since. Its a touring car. Jensen Interceptor w 24k original miles. So, no track time, but reliability throttle response and w.o.t. performance seem excellent. Original TQ and a reman TQ both were a nightmare even with all those other "tune up items", hence the Edelbrock was one of the last things we did. Heat crossover is blocked off, electric choke works nicely. Car weighs 4400 with the driver. Torque converter appears to be possibly hemi converter or other "hi stall" factory mopar. Anyway, the Thunder AVS really kicks butt.
