Fs: 4mil top end wiseco 65.50 virgin cylinders

BAM!!!

let me explain something because clearly the two of you above ^^^ are confused.

 

-when you run a spacer plate in between the cylinders and case your are compensating the additional stroke and correcting the port timing. people run this usually with unported cylinders and stock heads or cool heads with non stroker domes.

 

-when you run a plate inbetween the cylinder and head your only making up for the 4mm of piston hanging out of the top of the cylinder. your not changing any port timing. people usually run these with correctly ported cylinders and stock heads or cool heads with regular cut domes

 

This being said...theoretically if the builder of this engine had any common knowledge of building a stroker it would have ported cylinders. However i do not know this, i do not port engines but if someone could give some measurements of ports heights i could diffinitively determine wether or not these are ported.

 

But so everyone stops crying these are stock cylinders with long rod(115mm rod) 4mm crank pistons and they have been taken out of a good running engine.

how do you have 4mm going into the head?

Wow! Talk about a sale going wrong! Lol

Correct 2mm...but without a spacer plate on top Regaurdless of port and a stock head the pistons will hit the head, correct...i agree that you wont necessarily correct port timing using a spacer plate under the cylinders but it will be closer than using none correct?

200 for the cylinders 100 for the pistons if you dont wanna buy them together

When correctly setting up for a 4 mil the head is rechambered or more common is you buy 4mil do es for your cool head.. Then the cylinders are correctly remapped for the added stroke with the aid of porting..
