Yeah, I think so. When I pull the car in, I'll take pics of the damage. But it's not all bad - as I mentioned, the shortblock was wasted when I put it in - and just wait until you see my in-block fly cutting job! The pistons in the current block are "badger" brand hypers. Not exactly top of the line.
Now for the good - I just happen to have a good roller 302 on an engine stand in my garage. It came out of the ex-wife's 1990 Towncar from back in the day. I figure I can use everything from that motor except for the pistons. I'll get some decent ones this time - forged, reverse dome TW specific - any suggestions? Obviously, the cheaper the better. I'll re-use the crank and rods since I'm not turning over 6,000 rpm anyway. I'll just get the block cleaned, bored .030 over, new cam bearings put in and possibly deck the block - I won't bother align honing or anything - I know that motor ran very well (and smooth). So a sort of budget rebuild but with decent slugs.
I got to this point after talking with Matt - no point really in spending the $$ on stock block 302 stroker, when the limiting factor in this case will be the block. The rods and crank will likely hold up longer than the block, too. I'm open to suggestions on this one as well.
Looking at the pics of the deformed spark plug, I think I can see little bits of aluminum on it. You can't see them with the naked eye - I think the camera's flash highlights them better. We'll all know soon enough.
