yep, 25 min cam break-in and 15 min later the piston basically fractured ( we're guessing, couldn't get a replay on the in cylinder camera
) and the wrist pin went thru the cylinder wall, bent two valves cracked a valve guide and broke two pushrods. didn't even get to drop the hammer. got it rebuilt now and it's running well. race season is about to start. Chetwynd is a once a year event on the local airstrip. we have a full time track in Fort St John that has a race once a month and a track in Fairview 1 per month as well. Grande Prairie also has a 1/year enent as well. Dean's truck is just a warmed over 350, nothing to special. stock heads, moderate cam, Edelbrock intake and 650 cfm carb, headers and exhaust. he has a th400 tranny with a loose 3500 stall and 4.11 gears which are the main reasons for the quick times I think.
