As long as the block is 4.3l, no balance shaft and came from the
factory with a roller cam, then it is the same as a SyTy block. Crankshaft is same as generic 4.3, but bearing caps are NOT. You need to re-use your nodular iron caps from your old engine or convert the new block to 4-bolt (splayed) caps. SyTy pistons are also different, but don't go with GM parts there. Get aftermarket pistons (8.35:1, TRW makes the cheapest I'm aware of) and Eagle rods. Lots more info at: www.syty.net www.sytyauthority.net www.sytyarchives.com
