I've be tossing around the idea of building a procharged 427 ls for my 02 TA. I know they can't be bored much at all. But I was wondering if they could be resleeved to except a 4.07" or a 4.125" piston.

I have heard they can be expensive to resleeve. I have also heard they are a lot more difficult to do than the old gen 1 small blocks and mark 4 Big Blocks. If you guy have and experience doing this or thoughts on it?

 

Google ERL or RED. They might know something.
