Damn, what a bad Friday....It was running better than ever before!
Here are the details that we know now. http://www.shoptalkforums.com/viewtopic.php?t=74056 I'm sure we lost a part, probably a rod- will know next week and will share some pics of some of the carnage.. This is our first failure in 3 years, and this one was a doozey, I doubt anything is salvageable! |

These parts had been handling the power just fine for 3 years... Nothing was changed except the cam and it was just modified with a newer billet and modified lobe centers.
I made changes to the combo to increase the powerband another 800 RPM. The extra revs and added CR found a weak link somewhere. The engine previously would pull to 8K, but would not make power that high... Now the new combo would make power at 7,800 RPM.. It went 1 rev too high and scattered.. My bet is the rod bolts broke, they cost 30 bucks each! At these kinds of revs anything can happen. |
