Lainhart has a stroked 427 (487 c.i.) with 619 at the flywheel. 354 gears in a Jag rear end. Very streetable, very fast. You cannot just rev it up and drop it.
Get it rolling and easy into it.
Coach Mike has a stroked 428 (461 c.i.) with 601 flywheel hp. 325 gears in a 9" with MT street radial. FASSST.
600 hp is great for the street if you have the correct rear end gears and tires.
I've driven both Cobra and I love they way they cruise and the horsepower on TAP.
My small block makes 402 to the rear wheels.
But we're talking about 427's
600 hp is what a Cobra needs! IMHO
