4.3 Vortec Swaping

You need to look at the carb setup.

IIRC, the '93 has a TBI setup, which was changed in '95 to a CPI setup. I don't see why it wouldn't work, however, if you swap in the computer.

The 02 has SFI, not CPI injection You don't try to change the computer and half the wiring harness under the hood, and under the dash, you change the manifolds between engines IF the bolt pattern is the same. Also I believe the 02 has a balance shaft in the engine, the 93 doesn't. That means the engine is balanced differently meaning the fly wheels might not interchange, nor the front balancer which means the pulleys might not swap. will engine mounted sensors move from one to the other, doubtful.

My gut feeling is the engines wont interchange, with out major issues and work that make it economically unfeasible. Get a Target complete engine from Chevy (then you have 3year/36000 mile warranty on the engine). With enough effort you can put most any engine into most any vehicle, be it a V-8 in a Vega, a 3.8 super charged Buick in a Chevette Scooter, or even a 340 tri power in a 76 Plymouth fast back Arrow.

Good reply.

Now maybe someone can tell me how to put a Duramax 6600 LBZ in a camaro? :P

In reality prior to the Camero that went to strut suspension in the front, that wouldn't be that hard of a conversion. All the earlier Cameros ie

Well then, can I do a swap and install a 350 LT1 into my Sears rider mower, want to cut down mowing time :)

if you have a torch and a welder you can.

I'd much rather build this...

Sure can. I have driven a Cub Cadet garden tractor with a 350 in it. Also know of a couple with 4 cylinders from other cars.
