If you use a sintered bush, make sure you oil it correctly.

The only time it even does anything is when you're sitting still with the the clutch pushed in. Or just a teeny bit in between shifts. If you've got everything aligned properly a bushing will last a thousand years.:cool:

That's correct, but they last way longer if soaked in oil first. ;)

And the guys over on the Practical Machinist (which I am neither) forum actually heat their oil up before soaking. Oilite Bushing Grease or Oil??

Well I had one of those funky sealed bearings on there so I thought I'd replace it with the same since it worked fine.

Did I read somewhere that Tremec's called for the bearing style rather than the bushing? It's a McLeod clutch if that makes any difference.

No, you are imagining that.:cool:

Some wear, but maybe I'll just put the one I've got back in.

Nope, now that you've touched it with your fingers it's contaminated and will have a shorter life -- just like the 500w tube halogen bulbs that go in my garage trouble lights. If you touch them, they die.:cool: Go with a new bushing.

I wouldn't reuse a ballbearing pilot bearing.
Even if you knocked it out by the outer race, it's not worth the risk for a $10 bearing.
A sintered bush can be soaked with oil with the pressure from your thumb and index finger until you see the oil weeping through the porosity of the bush.

No, you have to take one of your wife's nicest pots, fill it up with about two inches of Brad Penn, heat it up to about 170 degrees on her kitchen stove, you can use your wife's cooking thermometer to check that temperature, then put your bushing in it and cook it for a few minutes. Then pour the oil down her sink drain, and pop the pot in to the dishwasher. You should do all of this when your wife is not home, of course.:cool:

The rule of thumb with bearings or bushings is that it depends on the clutch disc material, not the transmission. An organic disc is very easy on bronze, but a disc that has a sintered material on one side can have dust that will contaminate and wear bronze, so it's best to use a bearing in those cases.

Mine is a McLeod 500 series disc part #260571 (organic/ceramic material).

A bushing would be ok with that disc.

Let's see now, who was it that said, "A man's gotta know his limits ? ..."

I know this clutch is rated to 500hp. I'm not gonna have issues with the new motor am I?

Oh know! The old "when I increase the Hp of my motor, what else do I have to do to my car" question.

Let's see.

Will the fuel pump supply all the fuel the engine will need?

Will the radiator cool this beast?

Will the exhaust constipate the engine to no Hp gained?

Will the clutch slip at higher torque?

Will the transmission handle the torque?

Ok, I cannot torture you any more. I think in your case the tires will slip before the clutch, so you are likely OK. If you go WOT in a tall gear where the tires stay hooked, then you can put all the motor torque through the clutch, but the light wieght of these cars, should help.

There is the theoretical Hp/torque increase of more cubic inches, but if the exhaust was limiting the old engine, there may not be a real increase in Hp. However there would still be an increase in torque, below the rpm where the exhaust constipates the engine and clips the Hp. So I would be thinking more about higher torque.

PS
See if you can find out how much torque it takes to slip the clutch. That would depend on the clamping force of the pressure plate, which would be the biggest factor. The coefficient of friction between the clutch and flywheel on one side and the clutch and pressure plate on the other side would be the second factor. However if Brent says he has experience and the clutch is good, I would take real world experience as the gospel.

Should be ok.

The Holley 830 calls for a min of 3/8 fuel lines. My fuel log is an old school original with 5/16 hose barb fittings. The rest of the fuel lines are 3/8. I never had a problem with the Holley 780 on the smaller motor. Am I going to have an issue now?

Actually, I guess 2x 5/16 fittings still flows more than the 3/8 fuel line, so I should be good.
