**600hp sbm block limit? Or is it bs!!**

I ran my 360 that was in my Duster for 3 1/2 years before I tore it down to check everything and add some power. At 529Hp from my dyno, it looked great. No cap walk, nothing. It was hard blocked and I took care of it, but it was foot braked.

Added 30HP to the engine by upping compression .75, larger FT cam, and a 1000HP carb over my old 950. Foot braked it for a few passes then went transbrake/2 step. I put less than half as many passes on that engine as the first and upon teardown there was MASSIVE cap walk!
I was really surprised. I never mixed fuel, always ran VP110 fresh in the 5gal cans. I attributed the cap walk to the transbrake/2 step and having to launch such a heavy (3320lbs with me) car.

I've also seen a block from a 550HP bracket deal with a cracked main after 300+ runs. That's all I've seen personally so it looks like since I've seen very few failures that my not exist???? LOL!

Couple Questions.....

1) What was that engine Revved to at launch on the brake & at the end of the track?
2) How was the bottom end set up, was it studded? or did you use a girdle?
3) Was it a Forged or Cast Crank?
4) What kind of Rods did you use?
