PISTON RING SUGGESTIONS...440??? - 02/07/12 04:59 PM

I'm in the process of freshening-up the .040 over 440 in my GTX. When it was rebuilt 6 yrs. ago,Total Seal "Gapless" rings were used. I believe some of the blame for oil getting past the rings...and into the combustion chambers,could be attributed to the rings..along with intake port gaskets. What are your recommendations for a street/strip,11:1 comp. 440? Thanks in advance for your help! Randy B.

No need to even worry about getting fancy with a ring pack for that Randy. Go with moly top, ductile, standard or mid tension oil, and dont waste anymore time on it. That application simply doesnt require anything else.

I really like the Mahle rings. Nice flat finish, fit and size well, and they have a smooth fit.

They old tried and true Sealed Power almost always work well, just at a much higher cost.Been using the Total Seal CR series for many many years as well.

I'm not sold on the NEED for gapless, other than a few specific ( usually some alcohol) type engines.

Thanks,guys! I just want to go with a proven ring combo! Definately don't want the oil control problem after I put the motor back together! I will also be buying a better rear main seal holder! My stock one has oil all over the back of the block! Best Machine?...Indy? Sounds like they both work well!

Steff,I plan on honing the cylinders myself. I still have to purchase a hone to do it. Raff only has small block hones...or I'd borrow one of his!

Id do it with a plate and sunnen machine Randy. Better end result for cheap.

Hello,

I'm no engine builder but I thought that honing didn't need the plates? Any Pro's have a some input?

Damon,I believe when the honing plates are torqued to spec(same as head torque specs) that it simulates the actual "distortion" of the shape of the cylinder...making the process more accurate...and ring sealing more effective!

Thanks,Cab! Any suggestions on an after market rear main seal holder? I DO NOT trust using the stock one again! NO OIL LEAKS ALLOWED!!!

You do want to use a plate.

The BEST rear seal holder is a nice piece. I use both theirs and Indys without any issues.

Use the Superformance rear seal and side seals.

Thanks. Good to know. I was thinking it was necessary for boring but not honing.
