We are trying an EFI setup for a 440 and one of the main parameters we have to enter is "rear wheel torque value".
440 - .030 with six pack pistons.
3906 heads that were cut .020 or .030 with steel gaskets.
MP .455 lift 272 duration hydraulic cam
Has headers, mandrel 2 1/2 out rear, Street Dominator intake
What's a decent guess at rear wheel torque???
THANKS!!!

It's got 3.91 gears and a 518 4 speed trans.
Asks for a rear wheel torque and says it defaults to mild Chevy 350 specs which it says is is 300 ft lb....

Rear wheel torque would be flywheel torque times 1st gear ratio times rear gear ratio and would be a figure in the thousands. This is with a manual trans w an auto the torque converter would increase it even more....
Take care,

Rear wheel torque would be flywheel torque times 1st gear ratio times rear gear ratio and would be a figure in the thousands. Only if the program is expecting MAXIMUM torque at the wheels, and not the ratio in a direct (1:1) high gear. OP didn't specify. And don't forget to divide by 2 since half goes to each wheel.
