Damn...sorry to hear that, I bet that sounded horrible when you cranked it over. Don't know if it can be repaired, looks like it's in a vital spot close to the piston and all.

Yes , intake was off. The right head looks fine, it's not cracked or grooved.

We are thinking about ls3/ls7 swap now.

That can be fixed. A new sleeve. Any reputable engine shop can fix you up. But you may be close to spending as much as just finding another block. So do a little research

If it's just the sleeve, it can be fixed. However, it's probably going to be cheaper and less hassle to find another LS1 pull-out and install it.

Also, the LS3 engines have a different reluctor wheel on the crank. It's not exactly a "drop in" swap without changing reluctor or converting to an E38 PCM.

reluctor wheels are pretty easy to change. A little heat and they come right off. Throw the replacement wheel in the oven at 350 degrees for a half hour or so and it will slip right on.

I realize how easy they are to change. I swap over 10-15 reluctors a month.

The internet is always quick to yell out extreme recommendations. "Hey it's blown up, throw a 427 in it!!"....

He doesn't need an LS3 and I'm sure if the OP had intentions of spending a bunch of money on another engine he would have specified so. The fact is, this fix can either be done by re-sleeving or another pull out shortblock. Simple, effective, cheap. An LS3 is an awesome swap to do, but right now while that engine still holds a pretty high value, it's anything but cheap (unless you get lucky).
