Big Block Hp Capability
on this i'm going to say that the block had nothing to do with that hole. you said the block let go but i'll bet that it was a rod that no longer wanted to hang with the other seven.
the key to a stock block is keeping the internal parts as light as possible. the lightest pistons, aluminum rods, timing belt, a perfect balance job and the best balancer on the market. this is just like moper said. fill the block at least 3/4, bore and hone with a plate, aluminum caps, main studs and hone the main bore. you also will have to do the oil mods as well. l prefer the one where you drill, tap and plug the head feeds and turn the #4 cam bearing so the #4 mains gets full time oiling. also drill out all the main oil feeds to 5/16" and using a dual #12 swinging pick-up good hv hp pump with at least a 12qt pan. now the horse power will be limited be the heads that fit and flow the best, your cam, compression, carb or carbs and their size.
Koleno block $3995 from Hughs and as the add states "not ready for assembly"
So another $1000-1200.
This block let go last race of the season at Woodburn Or.
Didn't even Qualify for the event.
Rod bolt.
Even after market blocks and and parts have there limits.
