What size is my motor now.

[thekevin]

+4mm stroker with .080 over pistons. I did some looking around but saw people saying several different sizes.

I don't see 73mm pistons... I guess I'll never know what size my motor is.

Well that was fast.  Thanks for the info guys, I saved that chart.

Matt to figure your displacement, it goes as follows

bore x bore x stroke x .7854

Example stock shee is 64 x 64 x 54 x .7854 = 173.7, then x 2 cylinders = 347.4

LOL Matt knows how big his motor is. LOL (New member - 27 posts - we'll just let this one pass) But good answer.

Haha yeah, sorry. Thanks for the formula though, 1shee. I actually wrote it down on a card in my rolodex. Not even joking.

Fuck man, I'm in Real Estate, too many damn business cards to keep track of.

Sorry, I was having a flashback and picturing you at an old steel desk, in your squeaky wood chair, Rolodex on the edge of the desk next to your rotary dial phone, with one of those old ashtrays that had a vacuum feature to suck in smoke as your searching thru vintage Dirtwheels magazines stored on Microfiche.
