swade41: Ready to run gasser-gang this year? Plans for a bigger engine? Matt www.pro-formancespecialtiesinc.com/
Looking at the way this engine came apart - I'd guess there was a cyl clearance or ring gap issue in those two cylinders. I have experienced this before with almost identical results as you have posted up here. (I realize this is an old thread, I am just now seeing it) This type of a result from detonation would take much more running time to rear it's head - a clearance issue will cause problems very quickly. Just my $.02
sorry to hear about your eng failure. I too had a similar explosion with my big block 396 chevy mtr. made 4 or 5 easy runs, easy on the timing etc. brought mtr. back to the builder and first thing out of his mouth was i detonated the mtr. after bringing the mtr to another builder for further info. i was told the first builder bored the fly. to much and the walls were very thin.. this caused the fly. to crack allowing water in and hydraulic the mtr. did you sonic test the block after the mach work was done. good luck
Matt, I haven't touched the car since getting it up and running. I'm pretty sure I won't be out this year racing in the Gasser Racing Series ( http://www.gasserracingseries.com ), might try and have it ready for the Gold Cup with a new chassis hopefully.
