well when i wnet through the groupbuy for my block, the organizer said that 84mm and o ring wasnt possible so i listned like a mindless drone. now i realize i should just listened to myself and asked around more. sigh, anyways, im wondering what are the limits of a non o ringed sleeve/block compared to one that is? anyone w. any light on this subject. thanks,
roby.

lookn for hp in the 400 hp range. also, a builder here locally said that i was just asking for blown head gaskets left and right w/ out an oring...any validity to this statement.?

 

just get the cometic gasket with the thicker fire ring.

 

g no oringed block can hanlde over 800 hp safely. its been proven and tested

 

sgt, i am going to run a cosmetic..hopefully what this local guy saying is not true.
viren, if it can hold 800hp, then what is the point of an oring,,,just a ? hehe.

 

The orings are just a little extra assurance. You shouldn't have any problems if the motor is assembled correctly and tuned correctly.

 

You can make over 400hp without an o ring easy
