It needs a lot of boost to make that Triton displacement deficient tractor motor make any amount of horsepower
There's more heritage in the Corvette marque that a Ford built "replica" GT40 could ever emulate. If you want to count a significant racing heritage, Corvette's the winner there too. The GT40 was a flash-in-the-pan whilst the Vette has soldiered on for 56+ years. I like the Ford GT but when people get on their un-justified high-horses...
OBTW... the ZR1 doesn't need a tune, pulley etc to already knock down near 650 hp. It does it stock. That 6.2L has the ability to go much higher too, need be.
flame on...
