RE: stroke length

Title: Message

Z22 is the best to stroke however metal spraying is better than welding for that amount of increase.  I have welded and offset ground L18W cranks but only 2mm.  Always nitride and check straight etc. and they should all go to 9000 regularly and reliably as long as you keep it cool and oil clean -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Cleary Signs Sent: Tuesday, 15 January 2002 9:10 PM To: [EMAIL PROTECTED] Subject: Re: stroke length yerr but getting a Z24 crank to rev, i thought would nearly be impossible, Z22 a better option as they are counterweighted, Murray Coote used to get (can't remember which crank) either S2 bluebird or Z22 and get it sent down to Melbourne and weld the journals up and offset it to a 94mm stroke (why this figure?) (can't remember why it was 10 yrs ago?) he said the best L series L20 crank was the S2 bluebird something to do with castings between 3 & 4 journals, make them a 8500 rpm crank   my old 2 cents Heath ----- Original Message ----- From: David Costello To: [EMAIL PROTECTED] Sent: Tuesday, January 15, 2002 1:05 PM Subject: Re: stroke length why's that heath? more cubes plus boost is a good thing long as you build it so it revs   Dave ----- Original Message ----- From: Cleary Signs To: [EMAIL PROTECTED] Sent: Tuesday, January 15, 2002 9:53 AM Subject: Re: stroke length Dave, my idea would be to use a series2 bluebird crank, an not stroke it, as you arre turbo'ed it, but courses for horses   Heath ----- Original Message ----- From: andrew smith To: [EMAIL PROTECTED] Sent: Tuesday, January 15, 2002 9:41 AM Subject: Re: stroke length David, I would forget about using the z24 rods.The L20 rods would mean that with L20 piston that the pin height would be about 5mm to much so you need to find some pistons with 5mm less pin height.The z22e late model pistons list as a 32.1 pin height when compared to the L20 as 38.1 which is 6mm and you could deck the block if the comp was to low.These pistons are 87mm bore but unsure on the dish.Others on the list may have some better ideas.
