I was about to put the engine and transmission together on my v8 project today and ran into this problem.

Bolt circle measurement is 3.58"
I.D. of the pilot hole is 2.47"

Bolt circle measurement is 3.00"
O.D. of the pilot is 2.07"

Here's a couple pictures of how they fit.

I'm sending off an email to Archie to see what he can tell me. I was under the assumption that (other than really old 350 engines) all of the 350 cranks were the same.
-Perhaps I gave Archie the wrong ordering info when I ordered the kit.
-Perhaps he sent me the wrong flywheel.
-Perhaps his supplier supplied him the wrong one.

Regardless, I have a flywheel that doesn't work and I NEED one that does. The outside bolt pattern on the flywheel matches the pressure plate ( so I know that at least is right).

Any info would be great.
Thx

It looks like you have a flywheel for an 85 or older SBC and your engine requires the 86+ 1 piece rear main seal SBC flywheel.

Not without a flywheel, it isn't.

j/k. Trying to lightent the mood. I've had a crap of a day working on cars today myself, so I feel your frustration. I've found a nice tall glass of whiskey does wonders to relieve the stress of working on a car.

It does appear you have the wrong flywheel. As was mentioned, early SBC with 2 piece rear main seals use a different crank and flywheel than late model (post 86) SBC with a 1 piece rear main seal. I'm sure Archie will take care of it and get you the right part.

The SBc only uses 2 flywheels. For engines produced from the 50's thru 1985 takes a F/W that is 0-0 balanced (that's the F/W that you have).In 1986 GM wanted to use a one piece rear seal, at that time they had to go to External balancing because there wasn't room inside the crankcase to balance the rear of the crankshaft. So all SBC engines built in 1986 & later HAVE the one pc. rear seal & require the Late model balance F/W. These late model F/W's have a smaller center hub and a non-symentrical bolt pattern so that they will not interchange with the old style F/W.

When people call in orders, Once we've established wether they have an automatic or stick shift Fiero the only other piece of information I need is wether the engine is a early or late model rear seal.

The contractor I have making the F/W's has been doing them for more that 15 years and they haven't packaged them wrong yet. They charge me a lot more for the newer style F/W's than for the older style F/W's so you can bet I inspect them when they arrive.

If you can give me your name that you ordered the kit under and the approximate date you ordered it, I can go back and look at my notes to figure out what parts you ordered. But I can't recall shipping a kit to Edmonton in more than a year.

BTW: it would be nice if you could give me a call or EMail in advance so I can try to take care of you before you post to a public forum that you have "Problems" with something I sent you. It very well may turn out that the F/W I sent you is exactly what you ordered & maybe you were mistaken in what engine you were working with.

So if you want to give me a call at the shop tomorrow at 847-304-4480 We'll get it worked out.

I didnt take it as badmouthing you Archie. I took it as he was just puzzled it didnt fit and was asking for info. Two different flywheels explains the problem. Just somewhere along the line, some wires got crossed. Pooh happens. I ordered a BL (blue) Magnum and got a BL (black) Magnum. Salesman slip, no biggie, just took me a few extra weeks.

I didn't take it as badmouthing either.

The EMail I just got says he ordered it in 1999. It just seems he wouldn't have lost much more time in trying to get it sorted out off line rather than on the Forum.

As of right now I don't even know what the name is that he ordered the kit with. So I can't even begin to look up info on this transaction.

That's all, maybe a little fustration on my end of the deal too. Trying to sort this out on a Sunday, with no name to work with, on a sale that took place more than 5 years ago.

Not to mention that there are members who would take any opportunity to bash Archie for any reason, real or imagined.

Heck, the way I see it I learned something new. I though all SB flywheels were the same myself.

It seems I've done some learning and now I'm gonna have to shell out for a new flywheel. Business for you, extra flywheel for the next project for me.

Sorry if it came off as Archie bashing and sorry if it frustrated you. If you'd like, I can leave out your name in any further posts regarding my project if you're concerned it's going to bring you any bad publicity.

I'll email you pertinent information before I go to bed.

Not a problem, send me the pertinent information & give me a call tomorrow & we'll see if you want to trade that F/W in on the correct one for your application.
