Street stalker Hp and Tork limits on a drivable cobra, 450hpand 500 tor. This is at the crankshaft. A small block will handle a little better racing on a small track. The hot setup is a stroked windsor at 400 cid. Iron block Alum upper end. Now I have an Shelby motor, all Alum but crank,rods,cam and oilpan. Wieght is 520. The same as a windsor. Your motor is another 100 lbs on the nose of your car. You need to get the car wieghted and move wieght around to try and balance it out. My motor is 360 hp and 448tork, runs 12.5 in the 1/4 has 9.2 compression, will run on regular gas if needed. Build a motor that is easy to live with. 600hp is a pain in the neck at times, nice to leave that 300ft burnout but the guy with a 100 less hp is driving by you. These cars only wieght 2800lbs. My new motor is going to be a 489 with 10.0 small cam should make another 125hp and 170 tor. this is all the car will handle with street tires. Bigger is NOT always better.
Good luck with your car. Rick Lake
