Installed
Very nice custom plenum. I have the same Spectre plenum on the car now and made it work.
I do not see any heater hoses?

Check your timing, specifically the mechanical advance. The EZ-EFI does not control timing and with some of the light advance springs installed in performance engines, the weights are on the verge of opening at idle. The EZ computer sets the idle speed in neutral but the advance weights have advanced the timing a bit so the idle speed is up. As soon as you drop it in gear the motor lugs down a bit, the weights drop in and timing retards and the idle drops to a point where it stalls. This happens with carbs as well but with the EZ-EFI it is very touchy. Get the distributor recurved so that there is no advance before around 200-300 RPM above your idle speed in neutral.
Using one of the lightweight springs and the lightest of the stock springs has worked well for me to fix this problem.

it looks great.did you have any clearance issues with the hood?what kind air cleaner are you using?
Yes, the hood clearance takes some thought. You can't use a normal drop base air cleaner as it hits the fuel rails. So we ordered a Spectre aluminum plenum box and it only takes up 2" of space. Has (2) 4" inlets on each side with 4" tubes. I currently can't get the tubes to fit so we are just going to run the plentum box with fine pre-filter foam covering the openings. I will post pics on that soon and it should work fine.
Someday when I get some time the solution maybe using oval tubing to get the hood clearance.
This is in a '68 Charger with an RPM intake, so results may very with different combos......bottom line is can't use drop bases with the EZ-EFI.
I ran a TB years ago (projection) and it was shorter than the eddy carb that it replaced.
just thinkin out loud if your TB was shorter than a carb like mine was and you ran a holley street dominator, maybe a 68 unsilenced or other round filter would fit under a stock hood

. The guy installing it has had it for 3 weeks. The car starts perfectly but once put into a Reverse or Drive it dies. I think he posted about it on here earlier this week.
