now that all depends which 4.3L we are talking about they had a newer one that was fuel injected under the vortec flag

ill vouch for the gutlessness lol..It irritates me when i drive bubba then claudia cause its like wow i could walk faster lol ..But the torque oh the torque lol..The dist sits somewhat low i see it being more happenable lol with a 92-94 sc due to the shorter snout..there fore it could be positioned further forward..would take alot of desighning/engineering on cad but anything could be done..

Then you have do a head swap as well Gunner. I had the 4.3 in a '91 S10 and was stumped at little difference in performance vs my 2.8 in my '87. Never had the two together but I always thought my 2.8 5 speed could take my 4.3 automatic. Really, two football shaped custom solid motor mount plates for the 350 and it'* in. The difference in power is amazing and I've had 2 friends do it and glad they did. Really makes the little mule of the S10 get up and go.

If moneys not a issue, then a centrifugal supercharger may be a better option.

Have seen that done on 4.3/Chevy boards. But ya, expensive.

just mount a leaf blower somewhere and run tubing there ya go supercharger right there..hahha well trubo lol i did that to a 3 wheeler..sorry im just the resident redneck..don pay me no mind

Ya, like 5 or 6 grand. Under hood space is also something that needs to be taken in to consideration. And when using a M90 you will need to deal with the boost bypass. It can be run without it, but tuning is more of a pain.

Hey, welcome to the forum! Wow, what a conversation you've started!

I think the easiest way to use an M90 on another engine, with enough room of course, is to mount it upside down next to the engine and then do a u-bend intake to a carb-style lower manifold. The throttle body sits by the supercharger, and you should be somewhat good to go. Lots of fabrication, but not as much as it would take to make a new LIM or so.
