I am not exaclty sure what this means but i have an ati damper and the tech guy said it will work on a 90 degree engine and NOT a 60 degree engine. So wich one do we have?

Here are the numbers that are on the damper

sfi sticker-197880

a197880

On the hub with the o-ring-916980

On the center hub that slides on to the crank-916040

7 1/4" diameter acroos the entire damper

Re: Are our motors 90 or 60 degree?

I think hes referring to the bank angle
60 degree V6:
The longitudinal LR2 was a truck version produced from 1982 to 1990. It used a 2-barrel carburetor and produced 115 hp (86 kW) and 150 ft·lbf (203 N·m).

Applications:

1982-1986 Chevrolet S-10/Chevrolet S-10 Blazer
1982-1986 GMC S-15/GMC S-15 Jimmy
1984-1986 Jeep Cherokee
1986 Jeep Comanche
1990-1991 Isuzu Trooper

Ours are 90 degree V6's

This would actually be a interesting topic to cover....http://en.wikipedia.org/wiki/V6
this explains it better than I will be able to

I know, I tried to convay my sarcasm with the smaller letters for the thermostat (like I was wipsering it), but apparently that didn't work too well... :lol:

Thanks. I noticed that some guys are using a 6 3/8 balancer. My balancer is 7 1/4. Summit said this is the most common balancer used. Is this true and is this balancer ok to use? My friend gave it to me so if it's good i would like to run it.

the larger is what you want.

at higher rpms with the small one weird stuff can happen.

like you use loctite and you still have flexplate to crank or flexplate to tc bolts come loose.

been there and done that. guy at Ati told me about this when i wore out the id on the hub of my 6 3/8 ati dampener.

I would think the RPM range on the motor would play a roll in that. How high of RPm were you spinning at the time you notice the wear?
