Find the engine suffix code stamped on the pad in front of the passenger side head.

If you're going to rebuild it, then it doesn't really matter which it is, as you can't order a kit until you figure out if it's rebuildable, and how far it needs to be bored. (if at all)
Once you've had it hot tanked and magnafluxed, then the machine shop will measure the bores and tell you if it needs rebuilding, and what size bore it is. Buying anything for it prior to knowing it's condition is a bad idea. Don't ask me how I know this!

 

ok so i was wondering if you guys knew about wat the avearage cost to get a block hot tanked an presure tested

 

Around here it's around $80-$100 for hot tank and magnaflux. Not sure what pressure testing a block is?
