[tortuga]

i dont think there are too many out there without forged internals and the like, my rebuilt ford racing has a forged crank, very good pistons, forged rods, the Cleveland journals, a sill big juice cam, 4bolt mains, stout block, ported heads all of it...and it pulls HARD right ot where i lose my nerve and shift, usually about 6k...In one of these cars i really dont see a need to go beyond that. Canyon carving at around 4k is really fast with 3.23 gears and a tko 600...
