So does taking them to the drag strip every weekend and beating the snot out of it. Nothing compairs to that test

I beat my car on the street more than anyone on here races I guarantee it..............Hundreds of miles and many carbs tested on a weekly basis so, not the case...........

This motor was 512 ci, n/a on e-85. B-1 heads , 13 to 1 compression alum rods and main caps . This is the only pic have to show, wish I could show the front of the block around the timing chain area were you can see the cracks there also. Block was part filled.

Thanks for sharing that inforamtion
My current bracket motor is similar, 4.35 bore with 4.25 stroke, 6.700 RPM BB Chevy type H beam steel rods with Diamond custom pistons with around 14.0 to one now with a set of Victor Max Wedge heads on E85. Early cold weather 400 block from AndyF (Many Thanks ) with 440 Source aluminum main caps and studs, hopefully it won't end up looking like yours Not filled either
Did it fail during run? If so I hope nobody and nothing else got hurt
I have broke parts on a run and thought I was going to bend up some sheet metal several times, thanks to God I didn't get hurt or bend the cars

According to the data logger about 2seconds into the run it let go. My son said it just shook real hard and he reached up and shut it down . After seeing what it did it's hard to believe it was still running when he shut it off. He says he is lucky it happened early in the run.

I'm glad it didn't hurt him or the car
I've had a couple of motors let go in the 1/4 mile past the 1000 clocks, not good

Thank God for the diaper, it has probably saved his butt twice.
