Does anyone know a source for the crank adapter for attaching the degree wheel and for turning the engine? The one I have I bought from Powerhouse Products several years ago and it's a POS too loose on the crank and the slot for the crank key is loose also. Does anyone make one that's worth a dime?

I have had mine about 15 years (same Powerhouse deal) and works like a charm and is tight. Quality must have really dropped the last few years.

You could always machine the Powerhouse wheel hole larger, mount the wheel on a crank hub, machine slots in the plate for adjustment using the damper hub an pulley holes, and then use a normal crank bolt.

I know of no other large degree wheels out there but have not been looking either.

I have a couple of modified degree wheels that I use and do pretty much what Tom mentioned. I mount mine on the snout using the crank bolt and washer.

I’ve got the comp cams crank socket tool. Works well for me

I also have the Powerhouse Products crank-nut it and it works great.

I use the moroso one and actually have had it turn with it bolted to the crank with crank bolt and washers.

So i decided to use a crank pully as a template and opened up the center and drilled holes so now it now bolts to the balancer. I think it works alot better this way. It still gets tightened down with the crankbolt but can just use a socket and breaker bar or 1/2" ratchet.

I also have the one from powerhouse products and the keyway is slightly loose. If your not paying attention you might not notice but it is loose. What I did was to put a plastic bag over the crank before I slid on the powerhouse adapter . The bag took up the space and the adapter went on tight. I've been thinking about using a crank timing chain sprocket with the teeth ground off to mount my degree wheel. A used lower gear will fit on the crank nice and tight, it's just a matter of figuring out how to hold the degree wheel onto it.

I think the Comp and Powerhouse are the same. I agree the keyway slot is a hair loose on both. I had a machinist (who I bought a Bonneville form for my first 455) cut a tighter one. It will even slip into the timing cover with seal if you want to check things with an assembled motor.

So the answer is no one makes the tool for a Pontiac that is worth a sh*t and if I want a quality tool I have to make one. Thanks for the replies.

Seems like I remember that Butler used to sell a setup for a Pontiac...

Nothing that a proper size drill bit won't fix. 10 seconds and done.

Sounds similar to what I did.
Have old balancer drilled and tapped to mount wheel to.
Then just bolt assembly to crank.

Tin the Comp/Powerhouse is a pretty good tool, and you can shim the slot easily. It also has an allen bolt to lock it in place on the crank. Good enough I bought a spare.

I use the Comp one with (2) set screws/slots on it. It fits on and snugs right up.

I gave up trying to find one so I made one. I got a crank timing gear cut off the teeth on a lathe then welded it to the sloppy Powerhouse Products tool. Now it works like it's supposed to nice and tight and the key way fits nice too with no slop or back and forth movement and no marks on my crank from set screws. Since I don't have a lathe and don't have a welder I had this done for me but the guy is a real cool dude and did the job for $40 I really lucked out.

[Tom Vaught]

One my best day I could not weld like a couple of fabricators I use.
Nothing wrong with going to a Pro even if you have the equipment
Most would not turn their machine on for $40, you did well.
