It does seem that I have room to setback the smallblock about an inch towards the firewall. Is this worthwhile for a street/strip car, or is the weight transfer gains so minimal its not worth the effort? Fabrication of steel parts is not a problem, the exhaust is not built yet, and maybe now is good time to switch to an aluminum driveshaft. Thanks, Dave

I have heard that every inch you set back a motor back is like taking 60 lbs off of the front end and moving to the rearend.
I don't think it really matters much unless you have a race car. I have a 70 Cuda that is setback 4 inches and on a motor plate. The car hooks up coming out of the hole better than before we did the setback. But like I said this is for a race car.

I have heard numbers that for every inch you set the motor back is worth anywhere from 60 lbs to 100 lbs off the nose to the rear. On a street/strip car, I dont think it would be worth the trouble. And besides instead of just one inch, I would go at least 2 inches if I were going to go thru the hassle of moving the motor.
