- 65 BB 502 Cp /MSD ATOMIC EFI/ 2009-HUMMER H2
This has come up before but I thought maybe I'd throw it out again...The 502 in my 65 which has a 66 BB Hood is using the supplied Holley 850 CFM Carb. I am using a GM style Deep drop base air cleaner base. Also I'm using a 3 " Tall K&N Air filter..which I have to use to get carb top clearence.
Now here's the problem..I only have 2 1/8" from the carb Flange Base to the top side of the under hood. The AC base is spaced off with base flange gaskets so that the AC Top Lid Underside.... ( Which Is a K&N Flow Thru Top Lid)....does not hit the choke plate and push it over increasing idle.
If I raise the AC Base Up to high..then the top lid hits the hood. Now..If I use a chrome flat top lid I can pick up more clearence at both ends..hood side and choke plate side. But I lose the air flow thru the top design
What I would like to see is some sort of air intake from under the hood forward of the carb or my original idea of using the 66 BB hood grills as an air intake.
The Problem with that is..Air is rushing by the grills is creating a suction rater then a postive air pressure..
Now I know I have brought this whole topic up before .so don't flame me.... I bring it up again only because time has passed and maybe some one will have a brain storm..and come up with a fresh idea.
Any takers......
