Yeah, PI swap is a big thing, you won't regret it. $300 is OK, but there are better deals out there. I found some with 15K miles on a fresh rebuild, 3 angle valve job, resurface, etc for $250.

Depends what your future goals are. PI swap will raise the compression too high for a SC or a turbo. Not completely 100% sure on that though someone should chime in here for assurance.

You'll be at about 10.5:1 compression ratio with PI heads and NPI pistons.

You will also need the coolant tube that goes under the intake, and a alternator bracket. There should be write ups containing step by step instructions some where on this site. If not just do a google search and you will find several articles about it.

good luck

The pi cams an intake are where most of your gains are. You can run the higher compression of a full swap with a turbo or supercharger as long as you keep the boost down and have a good tune.
