NZeder Posted June 27, 2005 Share #2 Posted June 27, 2005 LY good luck finding one of these rare beasts. LY = Crossflow head = Factory Rally cars. If you find one you better sell your house, wife and first born. Is the cross flow worth it? I read that it only flowed a 5% improvement over a well setup non-cross flow.Nissan heads that I know of that came with the L6 Series (some on L20a, L20et, L24, L26, L28e and L28et.E30, E31, E88, N42, N47, P79, P90, P90a, O5L. I am sure there are others that I have missed.SeeZgarage for difference between the E31, E88, N42, N47, P79, P90 and P90a heads Link to comment Share on other sites More sharing options...
Victor Laury Posted June 27, 2005 Share #3 Posted June 27, 2005 When you find that LY, I'll take the OS Gilken Twin cam! :laugh:Seriously, I'm interested in what you find. I'm ready to have a head prepared for 44 mikuni's and lumpy street cam (bigger valves, opened passages, dialed in combustion cambers). All I have on-hand is an early E88. I'd like to learm more cause I'd rather not waste my money (less money to waste on strippers) Link to comment Share on other sites More sharing options...
Ron Carter Posted June 28, 2005 Share #4 Posted June 28, 2005 Victor take your early E-88 to Slover and have them do it up for you!! Link to comment Share on other sites More sharing options...
Victor Laury Posted June 28, 2005 Share #5 Posted June 28, 2005 Victor take your early E-88 to Slover and have them do it up for you!!Slover eh? Did they do your work? Haven't they been doing speed work since.... forever? Costly? Post some contact info. I was thinking of Mark DeGroff. He's done some respectable V8 race heads. donknow if that equates to L6 theory.

Ron Carter Posted June 28, 2005 Share #6 Posted June 28, 2005 I have 2 Slover heads, yes they have been doing L6's for 35 years + I understand that they are reasonable $$$. I don't have their number but do know that they are in the 818 area code. R Link to comment Share on other sites More sharing options...
