Wth! I keep seeing piston "kits" with no rings!

['00 WO-YA!]

I'm prolly gonna go 366 but I keep seeing piston kits with no rings, that pisses me off, how the hell are ya gonna offer a "kit" with no rings? Even Vito's lists their "kit" with the piston, pin, clips & gaskets with no RINGS, sheesh! I guess I'm just getting frustrated! I see some kits on ebay for like $275 but I hardly see where a set of rings added to the kit constitutes an additional $100! What am I missing here?

here is the exact listing i used. i think i offered him $140 and he countered with $159. they shipped it fast!

I got a JE piston and it came with the rings

10.5 to 1 compression $150.42
and here is a link to a 85mm gasket set

So the JE stuff comes with rings then? I wanna make sure I have my ducks in a row. I might do the 12.1, i'm betting with the overbore it's more like 12.5:1

 

[duneracerweston]

Run thick gaskets and you can probably run pump gas

I'm gonna get the deck height correct, make sure my quench is where I want it (tight as possible) & let the rest fall where it may. My new boss's have drag cars so I can get fuel now, yay!

 

[beastlywarrior228]

With the duration on your cam you may be okay on pump as long as you dont advance the timing

 

[DeadLastRacing]

Yupp, JE does ship with rings unless you request otherwise. Some guys just like the option to run a different brand of rings. I dunno why but the just do. The engine guy I visit from time to time has a whole catalog of just different ring brands and sizes. I had to order a new set for my piston as it was milled down from 85 to 84.5 and the rings I got with it were 85. (weirdness)

i know with the work i have done i couldn't burn AV100. i dunno what your planning to run, but i'm just saying.

 

['00 WO-YA!]

Plans are a 12.1:1 366, Megacycle .450, ported head, megacycle adjustable cam gear, Vito's +4 timing key, kibblewhite spring kit, new DID chain & a FCR carb, I think I'm gonna go ahead with a 39mm FCR, my next build will prolly be a stroker or a 400 big bore so I'll be ale to use the carb.

 

[beastlywarrior228]

Dont use that key with the higher compression, the lower compression piston and key will work good together though

 

[duneracerweston]

why not use the key? i use it on my motor why not on a 12:1?

 

[beastlywarrior228]

the key advances timing which increases risk of predetonation, its good with that piston because the compression is low enough

 

[duneracerweston]

With race fuel it would be fine right? And what about11:1?

 

[beastlywarrior228]

Ya race fuel will solve it. 11:1 will probably be fine but 11.5:1 will bw cuttin it close. Pretty much advancing the timing is the same as raising compression.

 

['00 WO-YA!]

I'm already planning for a better fuel, the combustion chamber is polished nicely as well to help prevent pd. Advancing ignition timing doesn't "raise" compression but I understand what you're saying. It starts the burn process in the chamber sooner & changes cylinder pressure.

 

[beastlywarrior228]

Ya they have the same effects but are you gonna run a higher octane now

 

['00 WO-YA!]

My new bosses run drag cars & I now can get 112, 116 or vp 110 from the local yammy dealer. I'm hopin my boss gives me the better deal though. They order bulk through Worldwide racing fuels outta Richmond, Va.

Anybody know the thickness of the 85mm Cometic head gasket?
