383 475+hp
holley 750 carb
31 front squirter and 35 rear squirter
I was having a hesitation issue when i hit the gas so I went to get some new squirters turns out that i should have a 650 carb not a 750.
So here comes the question stick with Holley or goto Edelbrock.
I am not familiar with Edelbrock but many say its so much better for street driving?????? Please help.
I thought my build was done........uuuuggggg:nerd:
Stay with Holly. I have not had much luck with the new Edelbrocks and I've tried them on my '69 and '68. I had an old Edelbrock from back in the day that worked fine. You should be able to use your 750 on that motor. Which one do you have?
Hollwy 750 double aed. Cant find the number because i dont have choke tower. My biggest issue is I am dumping fuel down the exhaust. I leaned it out a bit 1 turn out total on each screw. It has gotten better.
Speed shop says advance timing. When I did that it ran hot. Don't want that...
I am 16° at idle and I think 34 st 3000.
I also have to admit I like the red color of the new holley carbs.
Me, 3310-4 VS , jetted for 3500 ft elevations, 45 pv, 70 pri, 76 sec with 55 pv.
I have a 80531 holley 850 hp downleg , jetted for same motor, it makes the motor scream but does not have the crisp throttle response as my 750 and kills my 20+ mpg on hiway.
So 850 back in the box. Took it in on trade for a Demon I was unhappy with. Stick with my tried and proven 3310.
I called the guy that built my motor and then I called aed performance. The car sat for a while (3yrs) after I picked it up both told me separately that something is gummed up..
So now I will clean the bowls and metering blocksand aor bleeds.....hope that's it.
I am gonna tear tare the carb down starting tonight. hopefully a cleaning will do.
one thing i noticed was on the video of my cars run test my vacuum went from 9 down to 4 then shot up to about 20 wtf???????
though vac dropped with higher rpm
awesome news thanks.
I tore the carb down last night. The secondary had a bunch of black almost sand in it. I am thinking that it came from my black braided an hose. Maybe i didn't clean them out enough and some ran to the carb the first time i started the car.
I blew all of the metering block holes out with carb cleaner and air along with the main body. I cant put it bck together today (work gets in way some times) but tonight or Friday morning we will see.
I hope that was your issue and you find where it came from.... get it taken care of :beers:
