jworrall J like others, I got to ask the question, WHY?? Have you every driven a 600HP high performance car? Gone to a driver school? Most Cobras have NO power brakes, power steering, ABS, tracion control, ( unless you use your foot) short wheel base. If you are going to build a motor for your car, build 600ft of torque. This will give you 550 HP and still be streetable. Gessford Machine, Keithcraft, Barry R. and about 1/2 a dozen PRO motor builders can make you a nice engine for your car with enought power to scare the carp out of you.
Right now a have 514 HP and 535ft of torque in a 482 motor in my car. I have had to learn to drive the car different than wheen it had 368HP and 448ft of torque. Look up the old threads from Ernie (Excaliber) and his 600 HP motors and the pain in the butt it was. Look at what he's got now. Unless you plan to drive at 140mph all the time, build a torque motor. Torque moves the car not HORSEPOWER.
If you look in Hot Rodding, and a couple of mags from the last year, Jay B, Barry R, Joe Sherman have all build FE motor. I think Barry Has his Engine masters motor for sale or part of it. There is another company that sells motors cheaper that the rest on this forum. I don't have any info on being good or bad, but I always go with the if it's cheaper than anyone elses, this makes me worry about cutting corners.
