TrickFlow has a sweet combo. I can attest to that. Installed the Track Heat system right out of the box onto a refreshed stock block bored .030 over, stock crank and rods, new forged pistons. I have about $3500 total in the motor. All I had to buy extra was the rebuild kit from Summit that included the pistons and new lifters. I used the stock fuel rails, new 24 lb injectors to match the 75mm ProM. Dyno'ed at a modest but fun 290 hp and 320 torque to the tires through a stock AOD and 3.73 gears. Motor screams around town in my 91 coupe. Great kit for a daily driver. Really nice lope at idle, too.
