Well installing rings for my 383 rebuild. Installed a set of Speed pro R-9902 30 rings. I pulled them out of the box now I cant tell which is the top. I have been reading some conflicting reports.

The box did have a inner lip which was top and second rings.
Both rings on the flat side are blackish in color but then one has a chome end that rides in the cyclinder bore.
One ring said "top".(has black end)- I installed this rings in the top of the piston. The second ring I think. just had a DOT for "UP" (this had the chore end)

I thought I was all set. then I read on a few online articles that the chrome ring is the top ring.
Now I dont know which is top or second.
Any help
Thanks
Dennis

 

Hi Dennis, the moly ring should be the top....but dont go by color. You better call Speed pro and make sure it's right before you go much further.

 

Hi Ralph,
Sent you a PM. Give me a call

 

The second ring should have a "reverse twist". The face of the ring isn't square to the cyinder wall. The bottom of the ring is the larger OD. The bottom of the ring is a scraper, to pull the oil down the cylinder, on the down stroke. This may help if the twist isn't too small to detect.

RACE ON!!!
