This engine is 351 winsor based and not a FE. I agree that there is no need to use a FE type motor when you can use a big 351W instead.

Most of the head and valve train development done on winsors comes from NASCAR and drag racing 5.0 classes. The trend towards big CI 351's has come from Ford Mustang street rodders and the need for big HP numbers. Large CI 351W based motors with low compression, because of low octain gas, that will still fit into a 5.0 mustang engine bays have been the result.

500fp of torque is a lot. "IF" and I mean IF in capitals letters, you have tires with enough grip to handle that much torque the gearbox required will surely cost more than a 500hp motor will.

If I was going to do a new drivetrain I would begin with a Porshe box with LSD,50/50 or whatever is the best one as far as power cap. is concerned. Then a big 351W at about 450hp built on a Alum. block, heads and one big 4 barrel.

Get the overall weight down to 2300 pounds and watch just about everything go backwards in the rearview mirror.

Hummmmmm sounds like Rick's car.
