S-10 w/ 2.5 to 4.3??

[chevyman84]

I have an 85 S 10 with a 2.5 in it. It is also TBI. I was wondering how big of a job it would be to put a 4.3 thats also set up for TBI into the S 10. And would it be poss that the tranny off of the 4 cylinder would bolt to the 4.3??

you will need a 4.3 engine, exhaust, engine mounts, ecu and wiring harness for a 4.3. you will also need a tranny for the 4.3 as well and possibly a trans crossmember with mount from a 4.3. you might also need a few minor parts such as fitting, lines, etc.

Don't bother, unless you have lots of time and money.

so in otherwords, its an all around bad idea if u dont have the time or $$ to sink into it?
