A few people asked about my dyno numbers lately so here is a graph of my motor pull. Remember this is through a th400, 9" rear end, and slicks. This is an 11.8:1 408 with old style All pro heads, Futral custom cam, and a Vic Jr. intake.

 

numbers seem low, but what is a dyno for ahahaahahaa, Nice numbers anyways.

 

Gotta remember he has alot of drivetrain loss though. Whats up with the low tq number? Seems indicative of a very large intake lobe.

 

hp looks decent but tq seems down.

track #'s is what counts and it does it good.

 

Low torque is due to the cam and converter. The cam is a fairly big.

 

nice numbers just curious what does it do in the 1/4 on motor

 

250ish* range?

 

Bigger

 

Nice. I'm gonna be running a 262/270 cam in my 425. What does your truck weigh and what does it run n/a?
