I just put the block on the stand yesterday; I'll mock it up before final assy.the timing chain maybe rubbing the block
My buddy ran a 509 block in a Nova that ran high 9's, but it was half filled with Hardblok. It had over 350 passes before he changed to an aftermarket block, but still checked ok.Just want to know if this motor is at it's limit. Do I need to go to a after market block?
Thats an older block for sure its a nice piece GM built them and anyone who bought those blocks could put and caps they wanted on them. I have put a lot of caps on those blocks over the years. Those blocks were non priority oiling from what I remember.I have one of the first bowtie racing block casting 184 with a one-piece rear main seal, blind heads stead. It is not splayed mains and two bolt end CapS. Has anyone ever heard of one like this? I was wondering if it would be better than a factory 509 casting block?
always heard the best block to rebuild was a high millage one and thats what racers looked for,any core shift or block flaws would of showed up by then the more miles on it the better
