Hey Smothers.

Let me get this straight. Perhaps I am one off somewhere.

You have stock linkage.
You have an 11" clutch
You have a 157 tooth flywheel
You have a xxxx pressure plate

If I am correct, the problem is your flywheel. Well, stock your motor is balanced properly with 164 tooth 50oz flywheel.




So, with your new build and balance, I guess I don't know if you can switch the flywheel on that motor without screwing up the balancing.




Do you have to dissasemble to motor to swap flywheels? I have always had my parts matching (pretty much all old style SBF) so I have not run into that issue.

 

This makes absolutely no sense to me. They sell 164 tooth flywheels with a 10.5 bolt pattern....

EDIT: that is unless you are just talking this specific app. In that case n/m...

 

I could be mistaken, but I am pretty sure the guy who rebuilt my 289 said he put a 164 tooth ring on the flywheel. I will check Monday and make sure. The pressure plate is 11" as is the clutch. I do not know off hand what weight the flywheel is, but will check Monday. You are correct with the linkage, it is stock.

Here is what I am wondering. What did Wayne ( the guy who is putting the newly rebuilt engine and Toploader in the car ) see that made him believe the flywheel and engine are set up to accept a 10" clutch, and not a 11"? What would one look for to determine that??

I have more confidence in Ray ( the guy who rebuilds engines) then I do in Wayne. Ray rebuilds engines for a living, and seems to be very thorough in everything he does. Wayne is a Diesel mechanic by trait, and admits he does not have a lot of knowledge of manual transmissions and Fords for that matter. Maybe Wayne is mistaken, I just wonder what he saw that makes him think the engine is set up for a 10" clutch. Is there a difference in the diameter of a 10" flywheel and a 11" flywheel? I still don't understand what difference the # of teeth make other then the compatibility with the starter.

What questions should I ask Wayne if I can get ahold of him tomorrow (other then what makes him think the setup is wrong for a 11" clutch)?

BTW I dont know if you have to dissasemble the engine to swap flywheels.

Thanks again for helping me out here guys.

 

Oh I see; I hadn't seen that explanation before I last posted.

 

O.k. Talked with Wayne ( the guy doing the coversion who called and said its set up for a 10" not an 11") and he said the reason he didnt think it will work with my 11" is the pressure plate bolt pattern doesnt match up with the flywheel bolt pattern. So, I am assumming after chatting with some of you, that if I locate a pressure plate with the correct bolt pattern ( correct for the 11" clutch and pressure plate) AND has the same weight, It should all go together. Also, I will need to use a stock bellhousing (10"), but the 11" clutch and pressure plate will fit in there.

Would you agree with this senerio or disagree??

 

Ok, it sounds like it is all clear now. The bolt pattern is different on the PP. Perhaps you were sent a 10.5" PP. On purpose or accident, the vendor should help you fix the problem. Good luck.

P.S. the flywheel or Flexplate (either) not the PP is weighted and balanced.

 

Now you raise another question. 10.5 PP? I thought for fords, there was either a 10" or 11".
P.S. I'm aware the PP isn't weighted, I just mis-wrote that sentence.

Thanks again for the help.

For new style 5.0 they have a 10.5 which probably has the bolt pattern you fellows are staring at.

 

Talked with the guy who rebuilt the engine. He claims, because the engine is balanced, and he took some weight off the fly wheel to do so, it would screw things up if I tried switching flywheels for one that works with a 11" clutch. Looks like I will have to settle for an 10".

 

Ok, the only problem I see is that the bolt pattern might be for 5.0 style parts. I do not know the deal for that. You might want to call Summit, or Dark Horse Performance etc to discuss in depth.

Post all of your results here please. I want to keep involved and know what mixes with what.

Thanks, and Good luck.
