400 small block 153 tooth flywheel
I need to get one of these. Where's the best place? It's for standard shift and 10-10- 1/2 " clutch. I have a flex plate with the external weight added but I don't know if you can successfully do this with a stick flywheel. I also know there is a weight you can add between the flywheel and the crank. Don't know how it works. Looks like it would drive the flywheel back through the front pump.

Re: 400 small block 153 tooth flywheel (MikeM)
It is going to have to be an aftermarket item. Chevy never used the small flywheel/flexplate on the 400. Therefore, there is no stock, unbalanced 'wheel, available. Check out the topic, "Starter on 400 block", by Jack 71. I have posted quite a bit in there on the subjact. You might check your block for three starter mounting holes. If you don't, already, you'll understand what I mean, after perusing that thread. Good luck, and...

I have a 4+3 1985, 153 tooth flywheel with a 400 std. crank,, using the balancing plate.
My crank is internally balanced and the flywheel & clutch assembly is externally balanced,,,, or you can buy a flywheel for an internaly balanced engine for @ $170 if I remember correctly.
EDIT,, they changed their website so you might want to give them a call.

Re: 400 small block 153 tooth flywheel (ld85)
Larry:
I looked at pace parts. Didn't see anything applicable to my situation. Maybe I missed it.
I have a 1970 400 block with two piece rear main seal. Can I use a standard 153 tooth flywheel with the add on counterweighted plate? Where can I get the plate? Any drawbacks to using this plate?
Thanks,
Mike

Balancing Plate S/B & 454 B/B Chevy
speedwayotors:
When running a 383 or 400 S/B Chevy with a 153 tooth flexplate or flywheel, you need to have a balancing plate. These fit between the crankshaft and flexplate and correctly balance the engine without resorting to a big heavy flywheel.
Lets you balance your Chevy small block 400 or 454 engine with a 350 flywheel (manual trans. flywheel or automatic trans. flex plate) and a bolt-on balancing plate. Road and race tested. Allows use of lighter 350 flywheel to rev quicker. Precision stamped steel.

ld85s posts were confusing.

Re: 400 small block 153 tooth flywheel (Dan Plett)
Larry: I found that flywheel but it says big block only. Thanks.
Dan: What you are calling a balance plate is what I was referring to as a counterweight. Thanks for the source. Does this take longer flywheel bolts?
FWIW: A member on another forum has advised that Jeg's sell a 154 tooth flywheel for my purpose. Haven't taked to them yet.
Thanks again.

I don't have a plate in front of me to measures. Just a guess I would say the plate is approx .100" thick. My bolts were long enough I didn't need different bolts.
It's possible that an aftermarket vendor sells a 153 tooth weighted flexplate.
As CFI-EFI stated there is another topic discussing this.

Re: 400 small block 153 tooth flywheel (Dan Plett)
Somehow Id85 must have misunderstood the question, because he refered to a neutral balanced flywheel. Then he mistyped, I hope, because he made it sound, to me, like he is using an unbalanced (external balance) flywheel with an internal balanced rotating assembly.
I found a site with a 153 tooth, external balance (unbalanced) flexplate, for a two piece seal crank, for Ralph. I sent him the url. Unfortunately, it is an automatic transmission builder site, and they don't list any flywheels. In my searching, I checked the Hayse web site. They didn't show 153 T, unbalanced, flywheel or flexplate for two piece seal cranks. I e-mailed them to see if they might really have, or be able to produce the flexplate. I have not had a reply. You may want to quiry them on the flywheel. Start here:

Good luck and...

Re: 400 small block 153 tooth flywheel (CFI-EFI)
CFI-EFI is correct I did leave out one bit of info in my post above, I apologize for the confusion. I had to go back and reread what I typedn and saw the omission that CFI-EFI pointed out.:banghead:
My 400 crank is internally balanced in the front and externally balanced in the rear,,, so my stock 153 tooth Corvette flywheel was used with a balance plate and the entire setup, including my clutch,,, was balanced while mounted on the crank to within 1 gram.

Re: 400 small block 153 tooth flywheel (ld85)
Now that you explain it, I think I remember discussion of this arrangement a long while back. That is a most curious set up. Since it was spun up and balanced that closely, I can't figure what would be wrong with it. Just a curious set up. Thanks for the clarification. I was sure there had to be a "but" in there somehow.

Re: 400 small block 153 tooth flywheel (ld85)
If I understand this right, you are using a harmonic balancer other than the external balanced 400. On the back, you didn't /couldn't compensate and had to use the external balance plate. Is this correct?
My engine was balanced like a stock 400, external front and rear. I ran the 400 balancer and a 400 flex plate. Now I want to change to a manual transmission and go to the smaller flywheel. Based on what I have read here, all I need is the stock 350 flywheel and add the balance weight and I should be in business. Is this correct?

Re: 400 small block 153 tooth flywheel (MikeM)
Mike, the answers are both yes and yes,,,,,,
I have a nuetral balance harmonic balancer to clear the C-4 frame, 6 3/4 inches or smaller clears the frame,, or you can indent the frame to clear
Yes you should only need to external balance your setup with the balance plate and a 153 tooth fly wheel.
Only the starter will need to be a 153 tooth but I am sure you know that,,, if you have'nt already,,,get a mini starter you will love it.
Mike I' am sorry, once again, for leaving out the data that made this easily understandable,,
