[court9155]

I would call them on monday. Long as they are same size should work ok. I think they are 5/64, 5/64, 3/16? Be sure to check bore size first.

These are the rings in the kit............

Dont see why they wouldnt fit....

Haha and on summits website the rings are a match up to 1978.....

I just checked the K B piston website and those are the correct ring widths. Should be the same thru end of production in a stock motor.

Found the issue, well POSSIBLE issue.

With regards to the main bearings, THRUST flange:

"Fits engines with 3.624 in outside diameter flange only."


I am not well versed enough on 440s to say what diameter flange (thrust bearing) a 1978 440 crank would have.....guess I will know tomorrow?

I found the difference. Thanks to 440source and google!

Anyway, it is cheaper to buy all the parts listed in that "kit" form, seperately but use a tri metal bearing designed for 74 and later 440s. Total is $258 pro shop versus $266 pro shop for a kit with the WRONG main bearings for a 74 and later 440.

I post this for anyone searching this info at a later date.

Budget builds rule.

Yes, the main thrust flange is a larger diameter for the later bearings.

This kit seems expensive, as I sell a re-ring kit plus mains for $240.48

Could you tell me more about your re ring kits and where to purchase one as I would rather contribute to the local car and enthusiast community rather than a large chain such as summit. Tho they have received plenty of my money over the years.

The prices above are all pro shop prices through summit and do include mains.

Also do you know why they moved to this??

 

[69Bee]

They more than likely went to a larger flange for more surface area. As far as the kits, they are pretty much the same, just cheaper it seems.

260-1043 Sealed Power gasket set (74/80)
MS1277P Clevite Engine Parts (74/80 Large Flange)

I must have hit a car first, so the price is $253.71 for the truck kit. The only difference I see is the gasket set. You will also need a bathtub intake manifold gasket, MS96000. The parts I sell are only available to shops, and not to the end user.
