Some interesting replies....So nobody over +700hp stroker in a stock block? According to some on here, ours should have blown up 3 seasons ago...I have no doubt it will eventually let go, but I have a stock block sitting here, so I would like to build a spare.




I'm only running a 4.375 stroker in an RB block but It made 750hp at 6200 on the dyno at 34 degrees total.
I backed the timing down to 30 total since my friends son wanted to drive it and it ran
10.26 @131mph in a 3200# Duster at Vegas. I'm worried about it letting go so I'm looking for a nice aftermarket block as well.
