What to do now????
So I spun a damn rod bearing on my Z, and we took the bottom end apart, and low and behold the crank is super-F'ed. needs to be replace, as does two rods.
So since i need to do a full rebuild, im thinking cam, and boring it out 383, 408, etc.
Any ideas for a 4500$ budget, the best way to go. I want to be looking at 450-500 to the crank, off the bottle. but want to keep some decent daily driving reliability. My shop down here told me im out of my damn mind.

A good hone is about all you can do to these blocks without resleeving.
If it is a 98 block the sleeves are a little thin and you can only go .005 over to a 3.903" bore.
The 99 up blocks can go up to .010 over and there is a good selection of pistons in either 3.905" or 3.908".
