The torque peak is at 3700. 656 ft lbs. Torque is flat from 3500-4400 652 ft lbs.
The reason why I asked this question is that with 4 lbs boost, the same motor ( everything else identical )
made 800 at 5700 and peak torque of 875 at 3600. Amazing what boost can do...
Forced induction is a whole different animal. Not a good comparison really at all. put a Vic jr or dart on it with matched ports and either even a 4150 1050 carb on it. Cheap fix used parts.
