Another flywheel /clutch question

[Bluemonster71RT]

I used the search thing here and wan't sure if I found what I was looking for so heres the question.

I need to know what flywheel and clutch to buy as I never found my flywheel in the shop when I got my car back (long story) I have the a833 trans 23 spline and a 383.
If I recall correctly I once ordered a 11" flywheel and the guy said it would't work. He said I actually needed to get a 10.95. But not having my old one I don't remember how many teeth it was.  I have my old clutch which at best has 1500 miles on it but also not 100% it was/is actually mine. So a new one would be in order.  I have a starter that I am also not sure if its mine because it doesn't look like it sits in the lakewood bell correctly. But I wont know till its drivetrain install time.  So any help would be great.

Thanks in advance

Well I use the McLeod parts
 I would use a 130 tooth flywheel , 360953 PP & a 260821 disc
 this will work with the blastsheild although you can also use a 143 tooth flywheel in the blashsheild with different parts as well
 the starter has two positions in the scattersheild depending which flywheel is used

What would you choose for flywheel brand?  I think the last one I had was a Hays. I cant proove it now but the machine shop that re-did my motor said I should be around 425-450 at the flywheel.

get a good flywheel , buy a steel not cast iron flywheel , McLeod sells them as well

Well I use the McLeod parts
 I would use a 130 tooth flywheel , 360954 PP & a 260821 disc
 this will work with the blastsheild although you can also use a 143 tooth flywheel in the blashsheild with different parts as well
 the starter has two positions in the scattersheild depending which flywheel is used

I was looking up the parts and here is where the confusion is. Should I get a 11" or a 10.95 flywheel? I couldn't find the 360954 on summit they had 360953 however that and the 260821 are listed a 11". So does that mean that they are just calling it 11 and it is 10.95? Or will that pp and disk work on both the 11 and 10.95 flywheel?

[Chryco Psycho]

360953 is the Street PP for the 10.95" / 130 tooth flywheel
 Summit has it listed wrong , it will not fit the 143 tooth 11" system

Ok here is a dumb question; Is my 71 383 internal or externally balanced? I got to ordering the flywheel and was left with internal or external.   I thought I read that it was internal. But I don't have my balancer or flywheel to verify.  So aside from checking the crank out for cast or forged??? 

[Chryco Psycho]

what thickness is the front damper
 what year is the block ?
 only the 2 bbl cars after 68 had cast cranks & I think even the cast crank was internal balance

[Bluemonster71RT]

I don't have my damper so??? But if I remember correctly it was a inch or a a bit more.   The block date is nov 1970

[Chryco Psycho]

well being a 7 0 it could be a csat crank if it was originally a 2 bbl engine but with the thin 1" damper I would bet it is steel

[Bluemonster71RT]

well I am going to order the one for internal balance I guess the worst case is I have to return it.  Who said owning a #matching family original car was easy

[Chryco Psycho]

anyone else here know for sure
 as I recall all 383 & 318 were internal balance with steel or cast crank , I am right ?

[Bluemonster71RT]

Well somewhat good news I found my old flywheel and clutch.  Does it help to know what balance with the pic?

To me, I see a standard 10.95 pressure plate, a 10.95 disk and an neutrally balanced 130 tooth flywheel.

In Summit's catalog,  you can either buy:
1.  A new 10.5" Clutch disk and pressure plate.
2.  A new 10.95" Clutch disk and pressure plate, get the special bolts too.
3. A new 10.95" Clutch disk OR an new 11" clutch disk and use your old pressure plate.

Get your flywheel resurfaced at the machine shop too.
Use locktite on your flywheel bolts.
