He's got Scat crank and rods. I think he'll achieve his 12sec goal. This combo is close but better than what I'm running in my Chevelle and I've gone 11's.

Yes,now it sounds much better.

The 285 cam (if he uses that one) should make peak power around 5800-6000. That would put him shifting ~6300rpm. Put a 6800 rpm pill in the rev limiter and let 'er rip.

You must have a lot better luck then me, if I look at a cast crank crosseyed it breaks in two!!!! But at the same time, I've seen some circle burners run an entire season with a cast crank in a 3400 pound car. A guy here in town finished his second season drag racing a 3200 pound car using a cast crank and resized rods!!! If I tried it, probably wouldn't make it in the trailer first time out without breaking it!!!!!

Obviously it can be done, but you Never know when it will EXPLODE! It gives me 1 thing less to worry about if I go with a forged/steel crank.

I haven't broke a cast crank yet (*knocking on wood*) I did break the snout off a 4340 crank.

I do believe he would be safer with a forged crank. He is pushing the limits of the cast crank. I believe it's rated at 500 HP and 7200 RPM's.

I do have a friend that has the Eagle street/strip rotating assembly kit with the KB pistons, SIR rods, and cast crank that has run 10.90's bouncing off the 7200 rpm pill 40ft before the stripe. He finally put a throttle stop on it and backed it down to 11.20's at 6800 rpm.
