try this one for some info   http://home.att.net/~jason510/Motorspecs.htm     ryan     ----- Original Message ----- From: David Costello To: Ozdat Mailing List Sent: Tuesday, January 15, 2002 5:48 PM Subject: stroke mathematics guys I'm trying to teach myself how to do all the mathematics involved in deciding what internal parts to use and I seem to be stuck   Z24 crank is 96mm stroke Z20 block is 227.45mm height and most people use the L20 rods for this combo, they're 145.9mm   when I wanna work out what height pistons I need is it rod mm plus piston mm should equal block height, or does the stroke of the crank come into it some where   I was doing 96mm + 145.9mm and coming up with 241.9mm which was way above deck height even without adding pistons on top of that, then I realised the 96mm stroke of the crank is from the centreline of the crank to the centre of the part where the con rod bolts onto the crank (HAHAHA forget the name) so if I add that in I'd have to subtract 96mm from the deck height anyways, hmmmm I really should have thought about this some more before writing this email hahahaha it's all sorta coming clear as I'm typing it.   I'm assuming therefore block height is measued from centreline of the crank to the deck height, so when working out what combo of parts I need I just add rod + pistons and try to get a combo that is equal to the block height?   Dave --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
