When I find a nice standard bore or nice 30 over 4 bolt main they are way out of my budget. My question is has anyone taken a factory 2 bolt and drilled it for a 4 bolt main with good results? I've found some real nice standard bore 2 bolts in my price range. Is drilling to a 4 bolt as strong as a factory 4 bolt ? Anyone done this with good outcome ? Lucky I'm in no rush, so time is on my side for finding a good block within budget. My plan is to build a nice healthy solid lifter motor for a 1969 Camaro Street car with a few runs a year at the track. Mostly street driven. Many Thanks for thoughts, ROB
