Default 427 Chevy Block 2 bolt vs 4 bolt

Hi Guys, I've been searching for a 1969 427 Chevrolet passenger car block for a future project for several months now. I really would like to find a 4 bolt main. Most of what I have found are already 30 over and needing to still be bored or are 60 over. Not really interested in that. 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
