Sirk.240 Posted November 13, 2007 Share Posted November 13, 2007 Alright guys, I am trying to figure out what head I have on my 73 FairLady. The numbers on the head are E30, and I can't find anything on the forums through the search. Just trying to gather some info, thanks guys Kris~ Quote Link to comment Share on other sites More sharing options...

Tony D Posted November 13, 2007 Share Posted November 13, 2007 That is about it, 37cc chambers for the JDM 1998 Inline Six. This is the head I will probably have reworked in the off season for our Bonneville Engine (1998cc L20A) as the E88 with it's larger chamber just doesn't produce enough compression for our power production needs. A 79mm bore doesn't cut it with a 47cc chamber no matter how high you pop up the pistons! Not to the tune of 15.5:1 like we wanted for the smaller engine, higher than the 14.5:1 CR the bigger L28 had that we were running a few season ago.
