lokar has them for there kit. i would recomend seting it to the instructions that lokar gives you then taking it to a really good transmission shop that does aod swaps for the final adjustment.
If you're doing that with a Holley, then you are completely ignorant of them. Tune em once out of the box, then leave it the hell alone. It'll stay tuned for years.
I know more about holleys then you may think. I'm not going to get in a pissing match over my statement but "some" people are better off with something simpler and easier to tune if starting with a "used carb".Im sure you get to play with those 3 dueces pretty often to keep them in synch and on the up and up so what you may consider normal (tuning) may not apply to someone with minimal knowledge of how these carbs operate and has a home rebuilt carb that may have questionable parts inside it. Like i said the summit carb is the (holley) version of the autolite 4100 it is a "excellent" daily driver/street carb that shouldn't require nothing but a idle air and throttle speed adjustment out of the box knowing the design of them they should require very little to maintain its crisp responce/drivability for a long time.
I have NEVER had to play with the dueces to keep em in sinc or in tune. They've been doing the job now for 6 years set just as they way they were when I tuned em. THAT'S how much you know about Holleys. And a Holley is no more difficult to tune than any other carb. The myth that they are is B.S. pure and simple. If you're having to fiddle with a Holley to keep it in tune, then you've got an ignition problem, not a carb problem, or you're just the type of person that's never satisfied with anything. You don't want a pissing match, fine, then don't post inaccurate misleading information.
The myth that multiple carbs needed constant tuning stems back from the days when they were offered as options by the factory's. Back then, nearly everything had points ignitions, and most time's a dual point system was included with multiple carb setups. It was the points ignitions, combined with heavy point springs that made constant tuning a requirement. It was NOT the carbs. And solid lifter cams didn't help matters either.
Sooty Plugs I pulled the plugs and regapped them from .043 to .035 on the chance that my HEI ignition wasn't putting out enough spark for the larger gap. Haven't taken it on the road but it didn't smooth out the idle. Don't think anything changed. Six plugs looked good but #1 and #2 were sooty. Not wet or fouled, but sooty. Tail pipes are also black but I haven't had it on the highway much to clean them out. I'm spending a lot of time idleing trying to sort this out. New plugs are Autolite 26s and new wires are http://www.summitracing.com/parts/ACF-WR4017C/ Don't know who made my HEI distributor. Long story as to how I got it. Would sooty #1 and #2 plugs suggest where my problem is? I'm wondering if it means something is wrong in the right-side idle circuit. Like Bryant and the Holley book both said, I should be able to achieve a smooth idle even if the jets aren't right sized. BTW, a kit of jets is on the way. Supposed to be delivered tomorrow. I'm having more problems with bog than with rough idle. Haven't dismissed the possibilty I need bigger jets. Might be more than one problem. Current jets are 62s (621) which seems to be on the small end of the range. (Please correct me it that's not right.) With a 600 carb, lightly ported E7s, stock roller cam, shortie headers, I'm guessing I might need to go up a size or two on the jets. When I have the fuel bowl off to change jets, I'll have another close look at the air bleeds for the idle circuit. Right now I'm feeling like (one of) the problem(s) is in that area.
what type of intake are you using? on most dual plane intakes, cylinders 1 & 2 dont use the same side of the carb. this tells me that its not a fuel problem causing those spark plugs to soot up. i would try swaping the plugs and wires from 1 & 2 with the plugs and wires from 5 & 6. drive it and see if the soot stays in cylinders 1&2 or move to 5&6. as for holleys needing tuneing or not. any carb needs tuning when it goes from different environments. as air density changes the carb will go rich or lean. most carbs that are set and never tuned after fact are usually on the rich side. this allows for easy start up and relitively smooth operation. holleys bad rep is from there power valve. modern materials and power vavle blow out protectors have pretty much eliminated power valve problems. they used to fail and leak excess fuel. edelbrocks dont have a rubber diapram working on there power valve so they are not prone to this type of failure. the other thing is fuel leaks. holleys will be more prone to leak fuel due to there design.
Yep, dual plane -- Performer 289. Good idea to swap plugs and wires. My son is coming over this evening and MAY have a good Edelbrock carb I can swap on and see what happens. (He's beginning to take after the old man -- can't remember if he sold it with a pickup.) On another thread I asked if anyone has used the Pertronix FlameThrower distributor with a roller cam. Their catalog says its not for a 5.0 but their tech guys says its OK with the roller cam. Wanna have a backup ignition anyway before I drive to Florida for the NPD show in January. If I get confident that the FlameThrower and a roller cam are compatible, maybe I'll bite the bullet and buy the distributor and put that on. I was hoping for a LOT less expensive backup but if my HEI is causing these problems, I need to replace it. Got lots of things to try. Thanks for your help.
Not that im taking sides or did i read the whole thread but i havent touched my holley since i got it till just a couple weeks ago when i guess i bent a throttle blade. Great carbs hands down imo. When i had trouble with my car idling, sure enough it was bad gas or that time during the year where its hot one day and cold the next.
Geezer Smoke 64 jets were replaced with 67s and 90% of the bog is gone. May try a 68 when I feel like taking the carb apart AGAIN. Had to test it. No other cars near us and we did not exceed the speed limit. I like the 1-2 shift point under WOT. Vacuum gauge on the cowl is temporary till the carb issues are sorted out. Limited slip moved up on my priority list.
My Holley seems to run vry well no matter what the weather or temp changes. I like it. I don't suppose they cud have been in business this long making crap. It's just like everything else in life - people have their preferences for whatever reason.
