What exactly was the problem with the first engine? I don;t recall hearing any details of that one....

And what about the valve issue where the heads were pulled and fixed by the Pro Stock engine builder. Had some sort of dragging valve issue and hit a piston ???..........

#1 Pretty much......with really crap bolts I may add, ARP lists them for STREET use....

#2 Well it was several problems that were a combination of people faults, ours included to some degree, but Ma Mopar well she took care of it in stellar order for us , even having me up to Stantons to see the motor Dynod, dissasembled, inspected, checked and re-assembled....as well as some other work they were nice enough to include. Thats all that matters on that one to us.

#3 That was MY issue, there was a binding on one of the rocker collar retainer shims against a rocker shaft stand. Or a very good possiblity of a lock condition between the keeper and the rocker Clearance was a bit tight (on a NORMAL engine its only about .060 there on a DP about .040 , and on ours with the moly retainers we "tried" well it was a possiblity. Changed retainer, changed shim clearances and it hasnt resurfaced, even the head guy agreed it was probably a "combination" issue with those 2 items.

I like the thought of a diaper, saftey equiptment dosent scare me in the least, Ive landed on my head on a motorcycle several times at odd angles between 70-100 mph and walked away (ok not always walked away) but something to be said for saftey gear....

AND on our car the clearance around the engine would be fine with it.

The only thing that worries me is oil temp...thats it.....but till I use one I wont know I guess.....I like the "Pan" idea better because well....a)it looks trick b)its got an airgap and a place to but my hotplate pan warmer c)Im used to it, and I cant pull the pan without pulling the motor, so it would just fasten on then and I could put a trapdoor in the bottom. Just me being me I guess...
