304 flywheel casting number?

I am in the middle of trying to find a replacement flywheel for my 304. I have not been able to find anyone that has an actual casting number for the 304 flywheel. I believe the one I'm running now is from a 258. Can anyone help me? I really need to get my CJ-7 back together. Help!!!!
Thanks a bunch,

Jeana

Re: 304 flywheel casting number?

this is some info I copied from teh AMX mailing list.

please NOTE, I THINK it jas some descrepancies ALONG with some useful info, so dont take it as the gospel!

>Counterweight position: at 7:30
>Known to be out of a dead stock 1970 390 4-speed car.

>Crankshaft flange recess measurement: 4.650 (approx. 5/32" larger

>Counterweight position: 9:30
>Exact application: unknown. Believed to be out of a 72/up 360 or 401
>(304's do not have a counterweight)

Re: 304 flywheel casting number?

Thanks for the info. Now, are you saying I can use a 360/390 flywheel. I guess I'm a little confused. Set me straight if you can.
Thanks,

Jeana

Re: 304 flywheel casting number?

Jeana,
I have a factory original flywheel that came off the 304 I just dropped in. It was in front of either a T15 or T150.
I'll go out tomorrow and grab the casting #s/counterweight positions for you "manual" folks. That should muddy the waters a bit more[img]images/icons/wink.gif[/img].

Re: 304 flywheel casting number?

No, you need to use a 304 flywheel, and it should be pretty easy to find, since alot of folks seem to have them and then swap to 360 or 401s ( those are the harder ones to find!)

I had one on mine, but I threw it away after experiemtning with it a bit, Ive kicked myself plenty, since I never even looked at the numbers or counterweight stuff on it!
