Back in July '03, there was a thread that discussed CR w/ an LQ9 motor.

Big Tex wrote (about an LQ9):

"Bore= 101.6 mm
Stroke= 92 mm
Gasket bore= 102.616 mm
Deck Height= -.1524 mm
Stock Gasket compressed height= 1.3716 to 1.524 mm depending on gasket
Stock 317 head chamber volume= 71 cc
Felpro gasket comp height= 1.0922 mm
Felpro gasket bore= 104.14 mm"

Big Tex or anyone else know what the piston (+/-) cc's are for the LQ4 and if there are any other dimensions that are different between the two blocks? Deck height the same?

Thanks

 

I calculated out the dish to be about 8cc on the LQ4. Thats the only difference.
