4.8L to 6.0 Swap I searched but no....

Here is what it looks like.

The old engine is still in the truck.



Someone told me that there is a spacer/adapter thing on the end of the crank and it can be removed. You can see where there is a line there, will that seperate from the crank?

[RedHeartbeat]

If there are threads all the way out to the end of the crankshaft then that is not a spacer.

[Red03SilSS]

there are no threads. inside and outside of it are both smooth

[RedHeartbeat]

well, if the bolt holes are smooth for about a 1/2" deep then it may be a spacer. Only way to find out is break out the hammer and try knocking it off. I've heard there are a few that style, with the removable spacer. Billy at TRTTurbo told me of it and we tried removing a spacer on one he had but it wouldn't come off.

Hmmm hard to say. Does the motor have iron heads or aluminum? Looks longer than I remember mine being.

That doesn't look like a spacer to me....did you get a flexplate with the engine? What did it look like?

[thunder550]

OK I found another pic of a crank with a spacer attached. If you can pop that off you should be in good shape, otherwise it won't work.

[Red03SilSS]

Its not a spacer. the line in the picture is just s mark. Its one solid piece.

I read on PT.net you can have the old crank shaved down by a machine shop. is this true?

also how much do I need them to shave off so it will make it work for a 60e.

And Thunder
It didn't come with a flywheel.

I've never heard of anyone shaving down a crank, but that doesn't mean it can't be done. Shaving it down will require pulling it from the engine. If you're going to pull the crank anyway, I personally would just look for a newer LQ4 crank with the shorter snout and swap it out. You're going to need new main bolts and main bearings either way.

The yellow lines show where the flexplate will be mounted up against. The red circle shows what the flexplate goes around. The inner circle protrudes exactly 1/4 of an inch. Are yall sure this will hit the torque converter? It just doesnt look to be long enought to.
