Sweet, keep us updated. 89mm makes a 465 right?

[Silverfox@C&DRacing]

That is a 440 bore

what is the US conversion of 2 MM? i want to get a 416 and was just wondering what it is. is it .20, .40, .80,...?

[UglyMotha™]

uh well a 416 is a 87mm piston and it's a .80 bore over stock so does that answer you question

[BadA$$440]

Dont the IMS 440 kits contain JE 89m pistons? So is this the same kit but with a different sleeve? And will this sleeve be tapered lke the other 440 kits?

[Colby@C&DRacing]

Yes the IMS kits came with JE pistons. But that was a special piston the JE makes for IMS and can't sell it to anyone else. They now have a piston that is being built to their own specs and with a 12:1 comp ratio, That they can sell to there dealers.

OK, thats cool. What about the sleeve made for it? Will it be tapered at the bottom like the others?

[Colby@C&DRacing]

Just talked to JE the sleeve is a tapered sleeve but they have made some big changes to make it stronger.
