    4.3 block question

    I have a 99 blazer with a bad rod knock that showed up about one year after purchasing the truck. It's been sitting since last year from lack of time/funds, and I'd like to get her back on the road this summer. I've been searching craigslist for my area, but have been unable to find many 99+ vortecs, and the ones I do find are going for too much, with too high of miles to justify the cost.

    I have another vortec from my 93 bravada that runs great with lowish miles, and I'm trying to find out if I can use the block from the 93, and transfer everything from the 99 over to it. I think only 96+ blocks will work, but I'm not sure.

    Thx in advance.
