Distributors won't seat on intake.

Not that you need this Marc.
Its INSANE EXPENSIVE !
 
Its best bought for a Turbo or centrifugal super charger car build Marc.
 
At nearly 500 bucks I wouldn't put it on my motor, such overkill. But it does have that adjustable collar. I'm gonna pick up a one piece oil pan gasket tomorrow, start planning for the fix. I'll drop the pan, see what pump I have, 5 bolt or 4, then go from there. Something in the chain of parts has to be off for there to be such a large gap at the top of the intake to the mount of the dizzy.

There used to be other distributors with an adjustable slip collar for all Gen 1 SBC & BBC engines.
That's all Summit shows current.
Kinda surprised.
Did not research deep for other options yet.
 
$500 dollars in 1996 Bought me a Pro-Billet Distributor MSD, MSD 6AL box with plug in rev limiter chips, & a Full set of Taylor Race ignition wires.
It was Dyno day with my 1st Race Pontiac 455 in Joliet IL.
The Mallory Dual point distributor blew up apart when the engine hit 8500 RPMs.
The guy slipped the the dyno water brake handle & it was full throttle.
Engine lived.
At the time I was not Happy.
Good Dyno Torque & HP Numbers though.
 
Oh yes, An MSD Blaster 2 ignition coil.
I had to swap out & wire up on the engine dyno.
 
True that. I'll get under there and do what I need to do. The wear pattern looks normal, though.
 
Intermediate shaft measures 6". Everything I'm seeing here says SBC is 5.75". Pump has 4 bolts, it's an SBC pump. Now I know what I have to do.
 
Or not. I dropped the distributor in without the oil pump installed. It won't settle on the pad. I think the distributor hole is undersized and it won't fit the shaft. Wonderful.
 
After further investigation distributor hole is correctly sized, but offset is incorrect causing distributor to bind up and not seat correctly. Gonna send it to Brian and Mopar Bob to fix it.

Sounds like you will need the shorter intermediate shaft.
The distributor holes in aftermarket intakes are usually larger than the factory intakes.
Some are so big that the gasket at the base of the distributor doesn't seal very well, which
causes leaks in this area. I can't stand that. For some, I have made reducing bushings.

I tried using this on my 334 SBC. I put Permatex between it and the pad on the intake and
centered it in the hole and let it dry. When I went to install the distributor, I had a binding issue
because that hole and the passage in the block were not in alignment, causing the distributor to
not fully seat. I could have reset the bushing offset to one side, but I chose just to not use it.
Keep in mind that using the bushing would pull the distributor out of the block by the amount of its
thickness (.115") in my case. I felt that having the gear mesh pattern centered was more important.
 
Brian said that idea may help. I still need the offset error corrected, though. They are gonna set up the intake on a granite Starret table and 3D coordinate check the intake against an Offy intake Brian has and correct any errors. It may be the distributor hole is offset, or it could be the mounting holes are offset. Either way, it will get corrected. Thanks for the input, 302
 
You're welcome.
I had some brand new aluminum intakes where the machining was so far off that
I sent them back. So much for quality control and inspection.
 
This one sat for a few months and the return time ran out. And as we see in this thread, I thought the issue was a too long intermediate shaft. Next build I put it all together on the stand. This build we did all the long block in one location, then moved the engine to where the car was, then mounted the intake and dropped the engine in the car, then did all the finish stuff there. Live and learn.
