I have been looking into swappin a 350 in my 1991 RS, so my friend has a 1992 Blazer(full size) and his 350 had 200k miles on it and he said he would sell me the whole thing for about $250, but he said the whole thing needs to be cleaned and the bores need to be honed. would it be worth it to buy his motor and have it cleaned/honed and rebuild it a little? or would it be better to find a motor that doesnt have so many miles on it? since it does have 200k miles on it what parts should be replaced?

and for v6 to v8 swap i need a new wiring harness, ECM, front springs, Sway bar?,motor mounts? anything else

 

$250 for a complete vehicle isn't bad. The engine should be assumed to need a full rebuild, meaning cylinders bored, not just honed, new oversize pistons & rings, reground crank, etc.

I'd also assume different heads, as the factory truck 350 heads were performance junk (until 1996).

Plus read the sticky in the top section of this forum on the topic.

 

hmmm well it looks like it would be a lot easier to just wait to find the right deal and just get another camaro that has a 350 in it.
