where did you find a piston besides JE to do the 366 kit and what is the compression ratio?

 

[tcombs0064]

Ebay, Mines 1mm Over stock. it all came in one kit, Cylinder, piston/rings. So far its doing great for a new brand! And im not sure of the ratio man. I'll let you guys tell me.

According to that is just .75mm overbore. Ur gettin that exact kit? Not a 366. 85mm bore makes a 366.

 

[tcombs0064]

They quit selling my kit lol. it was a 84mm then then an over sized piston, i couldnt find the one i bought lol

 

[tcombs0064]

haha maybe you all could tell me what mine warrior is? Maybe a 360? lol

 

[elwood]

stock is 349 and 84mm is a 357. I just found this page it tells bore to cc up to 84mm

LOL call it a 357 then? Whats the compression ratio you think?

 

[warriorkid23]

I got the same kit, 84mm too. I hope before you installed the cyl you washed it out really good with dish soap and water. I know when I did mine the paper towel came out gray from all the left over material from boring it out.

 

[tcombs0064]

Yeah we washed it out real good. Hows your kit going man? Im still breaking mine in!

 

[warriorkid23]
