Thanks Dan!

Sorry if this has been talked about - i didn't find anything from a search... Wondering if anyone sells holley rubber parts that can withstand the destruction from ethanol (i'm talking the standard blends in my area which are ~ 10% ethanol). I'm thinking primarily about the pump shot...

daginsu, Did you ever try any of these adapters? Like you, not sure if the 15440 is really required if the 2732 works...i too am worried that the 15440 is too thick... thanks

Update... Installed a fuel pressure regulator and adjusted pressure to 5.5 lbs at idle. Replaced the metering spring to the 8" one (silver, i believe) and neither of these affected the part throttle surge problem. I also disconnected the vacuum advance with no effect either. When i check...

caferacerx, well, it's all relative! I can't compare unless i have a reference... I've got a wimpy stockish 318 - no way for me to know if the performance i have is limited by the intake unless i swap intakes and either make a seat-of-the-pants comparison (not very quantitative) or better yet do...

Curious about this too.... I have the sp2p on my stockish 318 (all stock except for 340 cam) and although i've heard about this intake being an economy intake, what is the actual loss in tq/hp vs RPM relative to the performer? I'm wondering if i were to upgrade to the performer would i notice...

bigdemo1, i will get back to you with the metering spring color. I bought the eddy calibration kit and bumped up the rod to the next level of richness for part-throttle/cruise. I will also get back to you about the vacuum i have at idle. Yes, i adjusted the mixture screws to max vacuum and...

Still have the problem... I increased the cruise mixture to the next level from stock keeping everything else the same. It helped a little but i still have a part throttle surge. There is no reason i would need to bump up the mixture more - the motor is near stock! The *only* other thing i can...

Thanks Abodyjoe - that's what i'm thinking... i mostly run Holley's but this is my first Eddy so i'm learning how to tune it... anyone else with specific Eddy experience who would recommend the same thing? Thanks!

Have a 1405 (600 cfm) on my nearly stock 318 (340 cam and performer intake, 4 speed, 2.9 gear ratio rear. I also welded the dizzy mechanical adv so that i can limit the mech advance and get a little more initial (per posts here on FABO). My total is set to about 32 (i can't remember when...

Believe you can find a chart of specs for all holley carbs through the holley tech pages. I've used it in the past to get my carbs setup stock... 68 in front sounds about right to me and actually may be a little lean. The stock pv i believe is 6.5 but yours shouldn't make much difference except...
