What are all the motors that came with a 58t crank wheel and what cars and trucks can I get them out of?

Did the 5.3 and 6.0 truck motors ever come in a 58t ? If so what years to look for?

There's probably some overlap of models and years.

I think the first Gen 4 was the LS2, which went into both cars and trucks.
The LS2 engines made in late 2004 and up until about Sept of 2005 all had the 24x reluctor. These 24x LS2's were still put into some 06 models such as all the Pontiac GTO's.

Meanwhile all the 06 Corvettes got the early 58x LS2's.

Supposedly all engines (not vehicles) made after 1 Jan 2006 are 58x reluctor.

Looks like the 58x motors will be harder to find.

Is there an easy way to convert a 24x motor to a 58x setup?

Maybe you should tell us what you're trying to achieve ?

Most people are converting in the opposite direction (ie buying new 58x engines, converting them to 24x to put in pre 2005 cars).

You need to pull the crank out and use an oven + alignment tool to swap crank reluctors. Cam gear needs to be changed also but they bolt on.

Well I found a sweet deal on a wiring/ecu setup that could run a 58x motor but not the 24x motor and was wondering if I could make it all work on my project but I think you just convinced me otherwise. :D VVVV

Hey,

Are you sure that the L33 is a 24x?
Also would you know if it has a Drive By Wire or Throttle Cable?

Thanks!!!
:)

There is a 2005 enging really cheap near me that I would like to swap in my 1999 S10.

Info I have says 24x only for the L33. It could be wrong info I don't know.

As far as I know all 58x had DBW.......but you can have 24x with DBW too, so that tells you nothing.
