Alot of good info posted but also as posted I think its just another factor in a whole mixed bag of factors in the total build.
Ive always tried to pick the minds of the racers who are currently/actively racing and winning at it. B cause they be doing somting right.
We started doing that in the early 80-s with our SS pulling tractor 466/6 blocks they have the bottom end design just like a BB mopar.
We machined all flush with a hint off the pan rail and ran an 1 inch thick al plate with long long bolts to absorb some of the shock.
Lookie here at whats screwed into the side of the block behind the motor mount.
Look at the factory cap milled down with a strap across it. Notice the factory forged crank, and stock block.
How much power do you believe it could have made, for how many passes and heavy road use over years and years? Could this run on pump gas with the right cam? I wonder why most people on here can break a block at 600 hp when I reliably made over 1000?
YOU MILLED DOWN THE FACTORY CAP AND PUT A METAL STRAP ACROSS IT
Shame on you for thinking out of the box and posting that modification on Moparts
Nice mods
It’s refreshing to see different modifications other than what’s typically seen here
