madkaw Posted July 9, 2013 Share #182 Posted July 9, 2013 Is that measured flush? What HG are going to run?[ATTACH=CONFIG]64440[/ATTACH][ATTACH=CONFIG]64439[/ATTACH][ATTACH=CONFIG]64441[/ATTACH]Installed the .040 over ITM pistons. Torqued the main and connecting rod caps. Looking good. BTW Madkaw...the pistons are flush with deck.

Diseazd Posted July 9, 2013 Author Share #183 Posted July 9, 2013 Yes......flush. I'm using a stock P79 Nissan head gasket. Link to comment https://www.classiczcars.com/topic/39741-new-engine/?page=16#findComment-427240 Share on other sites More sharing options...
madkaw Posted July 9, 2013 Share #184 Posted July 9, 2013 okay, just curious where this combo left you with the ITM pistons. So 1mm HG? Link to comment https://www.classiczcars.com/topic/39741-new-engine/?page=16#findComment-427245 Share on other sites More sharing options...
Diseazd Posted July 9, 2013 Author Share #185 Posted July 9, 2013 Whatever the stock gasket is.....I believe it's like .055 inches. Link to comment https://www.classiczcars.com/topic/39741-new-engine/?page=16#findComment-427255 Share on other sites More sharing options...
73str86 Posted July 12, 2013 Share #186 Posted July 12, 2013 My L29 engine builder had to mill the 0.030 over pistons a little off the top for his own peace of mind I believe. Otherwise he told me I needed a 2-3mm head gasket. I'd have to ask him exactly why. How often do builders keep pistons flush?

madkaw Posted July 12, 2013 Share #187 Posted July 12, 2013 It's not about keeping the pistons flush- it's about setting up proper head to piston clearance based on the head gasket used. Thru research I have read that the best set up is .022-.027 clearance , but that might be too tight for some comfort levels. It's all about ideal parameters to fight detonation.I'm running about .027Most stock Nissan L motors have a pistons above the block from .014- .019 Link to comment https://www.classiczcars.com/topic/39741-new-engine/?page=16#findComment-427464 Share on other sites More sharing options...
Diseazd Posted September 27, 2013 Author Share #188 Posted September 27, 2013 Went to work on the Z Doctor P79 head today. I geometried all the wipe patterns for the Isky Stage III cam and valve springs. All rockers centered out with .160 lash pads except 2 which were .150's. I use an old egg carton to keep everything in order. Hope to start reassembly soon.
