360 motor question

Mark, I have had very good luck with even late model 360 blocks. I have one .30 over with 4" stroke right now. I have been running it in my drag car for 1.5 years with no problems at all. It does have hard block in it though. My last 360 was bored 60 over. It lasted 6 years in a drag car before busting a hypertech piston and completely coming apart. I did crack a cylinder once after using nitrous for six months. I sleeved the one cylinder and ringed it and used it for three years after that. I trust a 360 block but I am sure some are thicker than others, Ray
