Just got my double keyed hub from Thunder. I'm sure they didn't use my hub, cause I sent it for a core charge refund some time after I placed the order.

But, like a bonehead , I forgot to measure my old hub before I sent it to them. While I did tell them I needed a 93 hub, I'd sure like to verify the size, before I give it to my machine shop and have them cut the matching keyways in the crank.

Can anyone tell me the correct lengths for the 93-95 hubs and 96-97 hubs? I've done searches and have only verified that there are 2 different length hubs for the lt1s - just didnt see anyone stating what those lengths were.

Thanks

 

my hub off my 94 is.....3.100" and the inner diameter of the hub is 1.235" (inner diameter taken from where it slides onto the crank)
i had my hub off laying in the garage cuz my new motor has an ati superdamper. thought i'd help you out!

 

Thanks - suppose I've got the right one then - here's the measurements I took on the new one:

3-7/16" from end to end
3" from front face of the bolt holes to the rear of the hub
1-5/16" ID

Anyone have the measurements on a 96-97 hub for comparision sake?

 

Time to resurrect. I'm in an exact same situation. I bought and balanced a keyed hub, but i'm not sure if it's the correct length for the Cloyes double-roller set up. The measured hub length is 3.130 from the hub opening to the hub face (the "ears"/ or mating point of the balancer. Is this the early or late style hub?

Cheers,
