Okay so i yanked a 99 5.3 ls with a 24 tooth crank found number 8 rod bearing was toast so bought a new crank ends up this is a 58 tooth crank, it will be a carburated setup with a howards asa cam and I'm planning on a double timing chain so heres my question. What all will i need to get to swap cranks without going to the machine shop?

Since you will be carbureted, what are you going to use to drive the ignition? That is where the different reluctors come into play.

I'm planning on a 6ls2 msd box

You can't be the first person to try this combo
Someone has to make an ignition deal for that setup. Painless wiring ??

Just change the reluctor wheel or call Lingenfelter and get their electric doo-hicky that changes the electrons to run the 24 to the 58.

I heated up the reluctor wheel on my crank with a torch and pulled it off and immediately installed it on a new crank. Easy to do.

From what I've read so far on my setup all i have to do is change the cam sensor and cam sprocket then install the crank with a 6ls2 box and it should run, I'm just not 100% on that since i am a fng to ls engines.

A '99 crank is likely balanced to the press fit rods whereas the 58x crank is likely balanced to the heavier floating pin rods. If you don't want to take it to the machine shop to balance it, you need to buy the floating pin rods and pistons, which are probably just as expensive as getting the crank balanced.

When i pulled it apart it has speed pro floating pistons in it already, now that you say that that may be why #8 failed and put it in the boneyard

You can change the reluctor wheel but it takes a alignment tool from Goodson to get it timed correctly. about a 20 min job if you got the right tools. Tool is about 200 bucks...

The MSD 6012 would work with 58x and a 1x or 4x cam, so my guess is the new 6014 will do this also as they made this one box do all the 6010 and 6012 did, plus other features.

Update on this thread y'all, I've hased out he details and i willtalked to a few guys and from what I've heard changing the cam gear, crank sensor then installing a 58 tooth crank will work on my setup. Thanks for everyones input look forward to getting to know you guys.

Hi Thef, you ALSO have a choice of fitting MY IGN-8 ignition box as it was made for the GM 58x (60-2 in 1986) Target Wheel as I was a member of the inventor team. (US Patent expired 2006)

This is what we PML/Wegner used when the LS "carbe" intakes were designed/dyno tested for GMPP.

The COST would be lower with better Spark Accuracy. (24xe = 2 degrees/58x = 1/4 degree accuracy)

THOSE who state a 24xe change is just BAD TECH.

The IGN-8 box ALSO has TWO GPIO's great for NOS, VVT, etc.

I would fit a Single Chain, my Avon Gear part as this is stronger that a DR.

What ever way u choose to go get the 6014. It works on 24 and 58 tooth.

Still a ways off on buying the ingition, still getting internals and making equal tq\hp numbers. Gotta move one big broad it's going in.
