Flywheel questions

Flywheel questions

the crank is a LA Enterprise Kyptonite 3.875'' stroke.

What are you running, and which 8 bolt pattern is it?
The 8 bolt cranks for LA motors that were offered by DC/MP and others used the Gen2 Hemi crank flange, the Gen3 Hemi has a different 8 bolt pattern (the Viper V10 also had 8 bolt and was yet another pattern, as did the Gen1 Hemi, but I'll assume that's not what you're running). None of them interchange, none are cheap.
If you're running a Gen3, you could check into a flywheel from a 4.7, which had the G3 Hemi pattern, and have it turned down to accept a 130 tooth ring gear.
An option for the LA would be to have your 6 bolt flywheel redrilled to the 8 bolt pattern- I wouldn't run it on the street, but it should be okay for idling on a run stand.

since the flywheel is only being used on the run stand, is it possible that at least 3 of the bolt holes on the flywheel would line up to the crank holes? it won't see anymore then 1800-2000 rpm on the stand. if 3 bolts holes lines up, that should work?

AFAIK it’s not going to be cheap.

If all you are doing is trying to get it out and checked out on your run stand, you can use a few pipe plugs to block off some of the holes and then redrill the 6 bolt pattern in it.

I’ve done that before on an 8 bolt aluminum flywheel. I wasn’t paying for a new FW after I hurt my 8 bolt crank.

I ran the hell out of it and it never failed.

That’s probably the cheapest way to get it done.
