Rebuilding Engine

[Sy370]

I know this has been talked about, I did search and read 60 some pages and just confussed myself more. I can get a 1993 4.3 for $150.00, my plan is to strip this block and rebuild it for a spare for my Sy. Using only the block and heads from the 93, and using everything else from my original motor when I would do the swap. Does this make any sense to anyone else? Or is there a better (easier) way out there?
TIA

Thats what I have been reading, but have conflicting info on wether they work or not? I will be buying the motor if only for the heads, but wouldn't mind having a spare motor ready to go either. thanks

Re: Rebuilding Engine

the balance shaft motor will work. you just dont might wanna go vortec heads instead of the ones that are one there. and 93 might be a non balance shaft TBI motor. they made both until I think 95. at least the TBI hung around till 95 but they were all balance shaft by then.

thanks guys, I think I am going to give it a try. I know that there will be a parts list a mile long once I get going on it. I don't need the motor right now, hopefully.. Just do some work on it here and there..

What's the number on the block? 073, 011, 061,756 are non balance shaft.

I don't know what the numbers are yet, it is at a freinds shop. I am in the middle of buying a house so it will be there for alittle while. I will get them as soon as I can. Thanks for the info.
