Clutch question

[Mighty]

I’m about to start my attempt at putting a super t10 in my wagon in place of the Saginaw. The local jegs said they didn’t have a 10.5 inch 26 spline clutch disc in stock but the website said otherwise. My brother told me to run it by you guys because he’s not 100% sure and hasn’t messed with any older 4 speeds for quite a while. Back when my dad initially did the car he put a Borg and Beck clutch in it and a hays disc. He didn’t know if I would need a specific disc for the Borg when compared to say a diaphragm type clutch? He assumed they are but said to ask. This is my first go around with an older 4 speed so sorry if my terminology is off a bit.

This is where I’m at currently……

I guess I should also add that the car is mostly just going to be a cruiser with an occasional drag strip pass but it’s not going to be a world beater. If anyone has any good recommendations on brands to look into/buy I’m all ears. I already have the rebuild kit for the super t10. Thanks in advanced

Flywheel needs to be ground. Pressure plate needs to be replaced so you might as well get a complete kit.

Something like the Perfection clutch 30005S.

Yea I'd definitely be machining some fresh surfaces on them at the minimum..

I was wondering about all of that. My dad said he thinks that’s the original flywheel but he can’t remember. My brother said he thinks it’s a SFI flywheel but neither of them know. That pressure plate doesn’t even have 3k miles on it if I had to guess so same with the flywheel assuming it’s not stock. Maybe I’ll pop it off really quick. I’m assuming that’s all just from heat? I doubt it has over 10 drag strip passes on it and that was all with a very mild 350 and stock rearend.

Looks pretty stock to me but I don’t have a clue.

The casting number comes up as 4.3 and V8 chevy internally balanced engines with a 2 piece rear main seal in a marine application. The N at the end means it is nodular cast iron.

Note at about 2 o'clock the starter teeth are damaged, I would have a new ring gear installed.

Just buy a new flywheel. Cast iron flywheels with cracks are biggest issue for clutch failure. Get a new steel flywheel and a decent diaphragm clutch.

 

[Mighty]

Yep, added a flywheel to the parts list. Going to do some reading on clutch kits tonight in bed I guess. Hell, was Borg and Beck even any good at any point in the past? I don’t want to buy something that’s going to crap out on me this fast again.

Loose the 3 finger style and get a diaphragm style pressure plate. It's outdated technology.
