Well, that 1 pin bore is not going to hold that piston, is the #3 exhaust valve bent?

Alan, thanks for the advice and under "normal" circumstances or if it was one of my camera's or a bike of mine alone I would wait.

BUT in our case time is not an option, its something neither me or my father are promised tommorow. We tend to learn on our feet.

And thanks to the directions, and advice here on CR and from people met here on CR alone (we me and the old man are kinda recluses because well we are busy) well....we do know what went wrong, the rod bolts failed. AND now we have a solution thanks to the "DP Confederation" as it were, Someone called and said someone just found an off the shelf answer from another brand L19 220kpsi...should be sufficient :) So I called them and they told me I checked Summit and Voila in stock...so tommorow a grueling 15 minute trip to Summit .... I will have to recheck the rod clearances as the spec is tighter on them and Im afraid of the crush, 63 vs 89 lbs torque....(and no thats not what Im going to install them by but) its enough of a baseline it could change my clearances possibly.

We work in parrelel tasks always me an the old man and were good at it togehter.....

Thats how we put the DP together in as short a time as we did, nothing painted in a corner everything happening at the same time.

AND we learn by doing, and failing and doing again, until we get it "right" we both him and I have a BAD habbit of losing interest at that point when we hit "top of the game" Thats what we both like and keeps us interested in racing of one form or another we have no illusion we will ever be the top of the chain.

We enjoy all of it, litterally all of it, we find ways to find enjoyment even in failure.

And were both too stupid to quit even when we should......so well do as we can and the cards have been dealt, well plug away with the determination it takes.

We learn by doing I guess is my point and we dont have the luxury because of circumstances to approach it in a ..... slower ? fashion, lest we may not have the chance at all.

RPM kills parts..........and the dangers go up exponentially as the rpms increase......I don't see anything much different on that engine than any other engine. Small block Chevy Stockers don't generally turn 8000+ rpm although some might.....and all would if they could and stay in one piece....and the engine continued to make more power at those higher rpms.

I am not so sure that 8000+ rpms is a good way to race and expect to make it thru multiple races. Generally staying in one piece is required to be successfull at racing. Stocker engines generally last a long time. Every run is not a record attempt on the ragid edge..........or one where you attempt to rotate the Earth......If you wish to race like that.....more power to you.......but making it to the next round is always a goal.....It's simple...ya can't race if your broke.....

I heard different from a good source. Even if that were true, my suggestion to you is the same as it was for Atlanta, run a little on the soft side until you fully understand your combination.

I didn't see any spun bearings in the pics on the site the link goes to?

Are there more pics?
