    Hey all.
    I have an '85 S15 Jimmy and I've decided it's stock 2.8l v6 isn't worth fixing.
    I read on the VIN breakdown that, supposedly, they could fit up to a 7.5 litre engine in these things.. Anybody tried cramming 454 into one of these things?

    just by owning an s10 and seeing the size of a big block, i wouldn't think it would fit. I may be wrong. You shoul consider a 350 or 383 SB maybe...

    I've got an T-10(S-10) Blazer and I want to do a swap too. I've seen a 427 in one, but I think that they had to whack the hell out of the firewall. It would be sweet, though. I'm thinking of a 327 or a 383 in mine now. Mine is also 4x4, so I have a little less to work with.

    Lots of available swap kits for a Small Block swap, and you might consider a nicely built 4.3 V6.........they rock. The only problem with a V8 swap is the drivetrain reliability once you start squishing the loud pedal............

    Actually, that's exactly what I've decided to do :)
    A 4.3v6 is less than half the price of the big engines (5.7+) I found.
    Plus I won't have to worry about beding my frame and busting driveshafts, etc by shooting 700ft lbs down it :)

    Thanks for the advice, all.

    Your going to need to change the tranny also. If you are going to need a new tranny, might as well gop with the V8. The 2.8L has a 60 degree bolt pattern while the 4.3 and V8s have a 90 degree pattern. Might as well pick up an engine and tranny out of a fullsize truck and use them together.
