Flywheel, LS vs Gen II Question
I have been searching the internet for a definitive answer to this question. I'm sure the information is on this site somewhere but I can't seam to find it.
I want to adapt a LR4 4.8L to a Boxster 5 speed Transaxle. I have a custom flywheel to adapt a Gen II SBC using a 240mm clutch.
Will the flywheel adapt to an LS style crank if I re-drill the bolt holes. I have read but can't confirm that the flywheel would be positioned approx. .4" closer to the back of the block. I have access to a mill and lathe so modifications can be done. I just don't have immediate access to a LS crank to verify any of this.
My bellhousing will only accept a flywheel 11.5" in diameter to the outside of the ring gear. I don't believe there is a stock LS flywheel that small.
Any help would be appreciated.

Rebalancing will then be necessary.
The crank depth can be taken up by longer bolts and a spacer....
The earlier LS trucks in the late 90s either had a .4" forward crank or used a spacer when they were bolted up to the 4L80-E (which had tq. converters that fit the Gen I/II/BBC crank depth.)
If your starter bolts to your transaxle, that should take care of it.
I suspect ordering a new flywheel might be a whole lot less fuss and safer than a re-drill.
