short block needed
1.Just get a stock low-mileage shortblock?
2.Or build one up with forged pistons ect?
3.Or buy a newly rebuilt shortblock?
Craigslist or junkyard for option 1 and 2. If you want a newly re-built short-block, just keep checking the classifieds....I picked up a all forged 383 a hell of a lot cheaper than it cost to build. Or just order a Golen 383...under 3K: http://www.golenengineservice.com/en...p-short-block/
