Hi All,

I have a few questions. I am new to the big block world and I just picked up a 454 HO motor. But it is missing all of its water fittings, and accessories and drives.

I was trying to figure out what to do for the bypass hose and fittings. I know they are 3/4" npt fittings, but what hose size do I need 5/8" or 3/4"? Also for the LWP I'm guessing it is just a straight hose that is bent a little to go between the fittings. Right?

OH and speaking of hose fittings, are the heater hoses 5/8" for both?

Also, I got a flywheel from a 1991 truck. But I just realized it may be for a 12" clutch. Does anyone know the bolt pattern for a 12" truck clutch vs an 11" passenger car clutch? I measured my flywheel and it measures 12.5" center to center for the bolt holes. And there are 6 bolt holes, each flanked by two holes.

Thanks guys!

the by pass can be used.. its a preformed hose... or you can plug it..

the clutch is for a 12 inch unit only.. the 10.5 and 11 both use the smaller flywheel....

I dont know the bolt circle....

I've heard of a few people plugging their bypass.

So why is that thing there?
