I just talked to the speed shop and I guess its bored 30 over now, and needs another 30, so it looks like it'll be aroudn a 414 when its done. The heads seemed to have melted part of the alimunum in the intake part so theyre gonna do something technical(Iforgot what its called lol) and reseat everything to get it to fit and save the heads.
The pistons apparently have like less then 3/1000's clearence (super tight and built like an NA motor as I was told) but the rods were pretty loose...
I'll prob speak to them next week and see what the machine shop says.
Anyone have good experieinces with JE pistons?
I guess theres a 5 week back order for diamond so I might stick with JE.

The problem is machine work will have to be started all over again which will make my rebuild much more expensive though wont it, since they have to cnc all from the beginning... id rather try to save the block if possible if thats the case.

I've got a S80 and on the fence as far as 370 or 408.

never had missing plugs, just the tops of them :p hahah.
I was at the chevy dealership this weekend looking at the new c6z's...
88k... **** that! lol.
But, my dad really wants me to fix the car and sell it and get a c6z instead. Then a cam, headers, intake, exhuast, tune and 150 shot and Ill be right back where Im at now
What do you think of the idea?

Looks like I'll be holding on to the car for a bit then since Im getting offers for 5k
