Technical What type of rings to use in my budget rebuild?

I'm freshening up the SBF for the '54. The cylinders are within spec so I'm just going with a ball hone to get crosshatch. I'm ordering a re-ring kit and am wondering if its best to go with moly rings....or? I'm just looking for the best seal possible. The motor will be a bone stock street cruiser backed by an AOD. Thoughts?
This is the kit I'm ordering............

I've done fine with plain cast iron rings on budget overhauls.

 

And as a note, the owner of Northern at one time was posting here. I like that company

 

Is there an advantage to moly? It's only an $11 upgrade.

 

On a brush hone rebuild, i have always been taught to use cast rings. Will work better when it comes to seating if your cylinders aren't exactly perfect.

 

Cast rings for a ball hone job. Moly for an overbore.

 

yup, moly ring seal a good, round, smooth bore well, and last a long time. Plain cast rings wear a bit faster, and will seat on a not-so-round bore.

 

Cast it is. Thanks guys, you just saved me $11!

 

Lol that's about enough for a bottle of STP to assemble it with

 

Oh, boy! You just had to go there, right? Lol!!

 

Yup, I'd use cast iron rings. I've had great results using them on a re-ring.

 

I really like hastings cast iron rings and have had real good service with them.

 

On a budget rebuild, use budget rings. Simple.

 

This got me thinking that we really are old throwbacks to the past. Back when, magazines like Hot Rod would run ads for piston rings. Can you even imagine going to a commercial garage today and getting a ring job?

 

In 1965 I was doing 2 8cyl ring&valve in the car in a 6 day week and take home around $175. The only things we sent out were cracked heads and pin fit.
