5.3 Vortec & SM465

Anybody done this? I need to know what bell housing i would need to mate an SM 465 to a Vortec 5.3. I'm running an Atlas II 4.3 behind them, but I need to know the bell housing or part number. Any help greatly appreciated, THANKS!

I have personally have not heard of anybody using a 5.3L with a manual trans but that is not say it canít be done or hasnít been done. GM didnít offer the 5.3L with a manual trans in any vehicle. I am sure it had to do more with emissions than anything.

The 5.3L is physically no different from a 4.8L or 6.0L so I wouldnít see any reason why you could not use a 6.0L flywheel , pilot bearing and the original 465 bellhousing. I am using my original 465 bellhousing on an 2002 8.1L with a 1978 spec Centerforce clutch and pressure plate in my rig. Chevrolet V8 bellhousings have been the same for well over 50 years.

Just an added note, the Vortec(at least mine) has a hole tapped at the very top and one of the two top holes not drilled. This leaves you with 5 bolts holding the bellhousing on.

Advance Adapters told me no problem on my NV4500 to 2004 6.0L.

Todd is exactly right. None of the LS series engines have a hole tapped in the 2 oíclock position of the engine bell housing flange. Donít tap it or you will have a nice coolant leak near cylinder #8. The General engineered it to mount with one less bolt on these engines.

Go pick up the August or September, I can't remember which, issue of Car Craft magazine.

They had a whole article on converting those motors for use with old(er) school transmissions.

For example, there is a special throwout bearing needed, as well as a spacer that sets the flywheel 0.4" out from the crank mounting surface.

can't remember all the rest, but check it out, very informative.

5.3 swap

Hey,
I just swapped in a 5.3 to mate up with the NV4500. You definately should call Advanced Adapters and just talk with them. This engine never had a manual and needs a special pilot bushing and flywheel. Advanced sells a kit and it was a bit pricey but is pretty smooth.

good luck

Did you have to do anything to the crank other than install the pilot busing? The 4.8l and 6.0L had manuals behind them but they both have different cranks vs the 5.3L. Why couldn't you use a 4.8l pilot bushing, crank spacer (I believed used on the later ones as the early ones had the solid longer crank) and 6.0L NV4500 flywheel?

I am just shooting from the hip as I have always just used autos.

pilot

I used AA 2 piece pilot bushing and flywheel kit. I am not sure about the 4.8 or 6.0. It was not cheap but it works great. Good luck

If you have any other questions or need pics i will send you my email.

I used an LS1 flywheel, the sm465 pressure plate (balanced together), the sm465 slave and the ls1 pilot bearring was only pressed in about 65% of the way to make up for some of the .400 of the shorter crank. sofar over 60K miles on the conversion with no issues.
