Well it looks like I was about due for a stronger bottom end. The valves had kissed the pistons and it looks to have a bent rod or 2

Are those from exhaust or intake valves? Did you have valve springs, or an operating waste gate when spraying?

Good thing you caught it in time. Would have been a speed bump in the build if you destroyed the block past the point of boring it out. Amazing these things keep on running with slightly bent rods, or I remember threads of people doing a HG job, and finding cracked pistons. Could have been just one more day of driving and it could have came apart.

....well if you have intake valves that are still open when the piston is at TDC..."Degreeing a Camshaft"....your doing it wrong.

I have springs and I have a gate. This happened a while ago I think. Buddy did a burnout while he manually shifted from first to third. It was off the rev limiter. Only time its hit the limiter. It would have sucked find out the block was bad though. Fingers crossed that's its all good as he hasn't completely dissasembled it

I think he means if you got intake valves hitting you got a lot more going wrong than high back pressure or rev limiters

I guess. Didn't quite come off to me that way. None the less I've seen intake and exhaust valves hit for various reasons. High BP, over revving and nos seem to only make exhaust valves hit on these engines. Not the same for others.

Carry on

Ya true. If that's not what he meant I guess ford did a bad job "degreeing" my cam shaft. LOL

I gotta ask, what was your limiter set at? Just curious.

Not sure. Whatever Eric sets his innovative tunes at. This was pre valve spring upgrade as well.
