Tig,
Is the motor set back a little from the stock location?

I am surprised it weighs that much, even with a driver.
My street 1973 Cuda no lightening, iron headed, iron block, full interior, Weld wheels is only 3600 lbs. (without driver).

1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1
