Hi,

 

I have actually a 1995 GMC Sierra with a 4.3l. Ns just discovered a 1972 350 motor and also 350 transmission. I am make the efforts to discover out if this will certainly be a basic swap or will I have to do any type of mods as far as mounting goes. Will my existing transmission bolt as much as this motor? I plan on using the carburetor and ignition indigenous the 1972 motor. Thanks!!!!


As far as ns know, the trans you have should bolt ideal up, and the 350 should simply drop best in. Ns really doubt the 4.3L torque converter would mate come the 350 flywheel, and also I am practically 100% sure the 4.3L starter wont fit.

You are watching: Will a 4.3 manual transmission bolt to a 350

 

The T/H 350 infectious diseases worldwide is a more powerful trans than the 4L60E you have on your 4.3 though.

 

I'm sure it no be as an easy a swap as it should be, however for the old intricacy meter rating i would rate it a 6 - 6.5 out of 10.

Transmission, starter and so forth space bolt ons. Unless your 350 has actually a various flexplate than the 4.3 V6 go of course. You have actually 2 ring gear sizes, gift 153 tooth and 168 tooth. Even if castle are various all that affects is the starter.

 

Accesories should bolt up, many of the holes present on the late design blocks to be there from the previous as well.

 

The point to psychic is a 4.3 is nothing much more than a 350 missing 2 cylinders.

 

Motor mounts are different so you must buy the correct ones for a V8 in your case.

 

Then over there is the potential to require a heavier rad, you need a V8 trucks fan shroud and also so on.

 

It's no a disastrous swap really. Open minded if you want to keep the TBI versus going come a carb all you need is a V8's distributor and also intake manifold, injectors and also prom to operation it. Your choice however.

Yeah the engine should mount in specifically the same ar if I'm not mistaken...minus the actual mounts like you said.

As for the pan shroud, i wouldn't even bother...we put an electrical fan in my buddies K5 blazer out of a Ford Taurus, with a temp switch. The pulls way more air 보다 anything on the sector that's fairly affordable...(3000CFM every fan and there is sufficient area come fit 2 top top a full size Chevy rad)

As because that the pan shroud, ns wouldn't also bother...we placed an electric fan in my buddies K5 blazer out of a Ford Taurus, with a temp switch. That pulls method more air than anything ~ above the industry that's relatively affordable...(3000CFM per fan and there is enough area to fit 2 ~ above a complete size Chevy rad)

 

 

Just suggesting if he want to use a mechanically fan. I have to do that swap on mine 96 pickup...... I prefer the twin fan setup on mine 96 9C1 Caprice and also may just use one of those.
