if i use a compresion calc and do d16z6 block, head 0.037 hg, what piston deck height do i use, zc or z6, or somesthing custom.. if i use the z6 ptdh i get 13.6:1, if i use the zc ptdh i get 12:1 comp.. so what ptdh do i use for putting zc pistons in a z6 block/head

 

ttt

 

here's the problem, 11.971379041131721 is what happens when i get the awesome 1. using the

Deck Height - Compression Height - Rod Length - (Stroke/2) = Piston Deck Clearance

values, (%i6) 212-29-137-90/2; with the sum being 1. and 1 being 1mm = 0.040 in

soo... everyone i've talked to so far said my comp would be 13.2:1.. this math gives me 12:1.. big big diffrence..

help !!! im not ******* half assing this engine build with internet forum say so knowledge

 

bumps in the night

 

bump for the knowledges !@@#

 

What did you cc the head at? What is the piston cc? What is the deck height?

 

dh is 212, 33.7cc, i dunno the piston cc whatever stock zc is

use the piston to deck height of whatever piston you are useing. in the calc

 

use this link http://www.zealautowerks.com/dseries.html

Static Comp Ratio 12.03 : 1

 

hmm, so with high comp valves should be 12.5:1.. i'm going to clay the crap out of this engine build.. lol

 

just to let you know, even though you don't need it anymore the piston to deck height of zc pistons on z6 rods, in a z6 is .040. if you are using zc rods then the piston to deck height is .020, because the zc rod is 137.5 mm not 137 like other d16's.

 

awesome.. so with my flat faced valves, light decking on block and head, that should bring just a smidge away from 13:1

My build will be 12.0:1.
