So....what's the question? Sounds like a good plan. I wish I wouldve been able to swap a 350 in my old truck.

are the mounts the same and what tranney should I use

I just got into chevy's a couple weeks ago so here I go.(People, don't rag me to hard now.)

Front K member - to support the weight and correct fit for the 350
Motor Mount
TH Series tranny if you are going auto. I have a TH400 with a slap shifter
8.7" rear end (DO NOT BE LIKE SOME AND GET A DINKY FORD REAR FOR CHEVY)
350 Flywheel
T.C Torque Converter
I think you might need a shorter driveshaft

Throw Ins...

4.11 gears
15" wheels all around

That's my basic setup on my Chevy S-10 V8 355ci and I can feel all 290'ish hp. I could have a hell of a lot more if I rebuild my dang carb.

Yes the 4.3 motor mounts are the same and the Tranny will also work if you plan on making over 400 horsepower keep in mind the rearend is the weakest link.

I have an 02 Blazer 2 wheel drive, I want to put a chevy 350 carb motor in it. I was told that I cant use the existing 460 tranny cause its an electronic tranny, also if I put a turbo 350 tranny none of the gauges will work. Help Please!

My name is John - Hi from New Zealand. I have a 2001 Blazer that someone had previously done some engine work on and left an intake manifold bolt in the the engine somewhere.
Two months ago the extra bolt found its way between a piston and the counter balance on the crank. It blew a 20mm hole in the sump and destroyed a piston. Anyway I am looking at putting a V8 Vortec to replace the engine.
I have a Chevy expert hear in NZ that is looking out for a Vortec between the years 96 and 99 he tells me it is the best swap as the current computer will run the new transplant. You just need the exhaust manifolds and the loom and move the radiator forward to make room for the extra cylinders. I'm still doing the research. Its a right hand drive so as yet I'm not sure if that will make a difference if I have a lefty engine. I assistance is extremely welcome.
