Gmc 1500 with a 4.3. New engine questions??

[doesntrundeep]

I have a 96 GMC Sierra 1500 with a blown 4.3. I just want to put a another 4.3 in it. Could anyone tell me if I can use a 4.3 out of like an s10 or blazer? I know I'll have to swap things like harness, intake manifold, exhaust manifolds etc. But isn't the over all engine the same? And is there a year range I should stick too?i figured 96 to98 or so but I'm no gm expert. Thanks in advance.

If its a vortec it should work. Id change the exhaust and intake manifolds though.

If you felt ambitious you could change the motor mounts, ecm, and radiator (including shroud, hoses, ect) to make it a v8. The vortec 4.3 isnt bad but a v8 is always nicer. A 4.8 swap could really boost power without much mpg loss.
