I will get some pics on here when i get it in-it looks good-kinda shinny.---Got a question-I am messing with a 750 Holly and im not getting vacum out of the port that goes to the vacum adv. i think someone might had rebuilt it and put the base plate gasket on backwards that is between the plate on the carb and the carb-NOT- the one that goes on the intake for the carb-i was told the 4 outer bolts were what to take off to get to the gasket an iv took them off and its still together i notice two other bolts in the middle of the carb where those 4 bolts where-do i take them off two? I don't know carbs very well i don't want to get into something thats a handfull on it-just wanted to check that gasket without having to dismantle the whole carb--help.

I got it firgured out-the base plate gasket was wrong one and i got one from a guy for $3.50 and its all on and i got vacum adv. now---thanks though. Thinking of putting this 750 holly on the mod up 350 i got but think it might be to much carb.? I got a 600 eldrbrock on it now-any input?
When you are talking about carb sizing and brand there are a lot of opinions out there. If you ask 10 different people you will very likely get 10 different answers.
Here is mine. Take it for what it is worth.
I don't think the 750 is too much carb for the 350 at all. That being said, I will put a little astrix beside it. Holley carbs are my preference for performance. Set up right they will be just as dependable, drivable, and out perform or perform with about any thing. So as a general rule. If you are pretty good with a carb then I would say the 750. If you want an easy carb that you do have to mess with, just hop in and go the 600 will be a good choice.
My biggest concern is with who ever rebuilt the holley put the wrong gasket on the base plate. Rebuilding a 4150 style holley is about the easiest carb you can tear apart.
If you decide to stick with the Holley, I have included a link to some great tuning info.

Ok-i agree-solid advice-thanks 66---i heard a holly can give as much as 20hp over any carb out there even at size for size. I am going with the Holly.

Got a question---i got a electric fuel pump from autozone thats rated 4-7psi and was wondering if that will be enough-i should be around 500=550hp. I heard unless its a aftermarket electric fuel pump that they can only go up to about 300hp? I'll get it if i need one but if not id stick to the autozone if its enough--any answers? O and i'll be running with a pressure reg. at 5.5 I was told to go with the holly blue tech and that the other one starve for fuel at the top end basicaly.---I think i'll just go get the holly blue tech. and put the other on something else---sorry answered my own question lol-being a post hor. I do have that engine in the 63 and am currently working on putting in that 400 tranny hotrod built for me---yes pics are coming-hands are tied right now but iv been taking some pics...

Yes a Holley blue pump should be more than enough for your combo.
500-550 hp. What heads and compression are you running again?

The engine is a 350 1974 rebuilt by oreillys stock heads getting a 180psi-double roll chain-hei with a super coil and weight set with plugs gaped at 40 instead of 35-16 degrees intial timing-hi flo theromostate-6800rpm stealth intake-headers with dual exhaust and flow master-using a car balancer-underdriven pullys on balancer an waterpump-electric fuel pump an electric fan-cam is a 480lift 288duration 110lobe 2200 to 6200rpm range-long sloted 1.5 rockers-cold ram air kit-750 holly carb-400 tranny rebuilt by hot rod with all upgrades an brand new stuff with the strronger spline an stage 2 shift kit-373 gears in the rearend-295/50/15 tire(25inch height). It weighs right at 4000lbs with out me in it. This is my set up pretty much. The type of heads nor the pistion are giving me that compression i don't think but it's the cam. When i had the stock cam i was getting 8.5 to 1 but when i switched cams it put it up to 10.2 to 1. I don't know what oreillys does/did to the engine i did'nt take the heads off to see if it was bored but id think they wouldnt do anything special but put it back stock and i just ran the numbers on the engine to make sure what it was. Im thinking of having it dyno tuned when im done-im probably out there over exauratring on the hp u know its the track that tells the truth-you can think you have 500hp but only get 300hp at the tire...It don't matter im happy with it-iv been working on getting this all done-i got the engine an tranny in and currently hooking it all up-when im done im going to put the engine an tranny that i pulled out of the 63 into my 70 c10-then its the 454 time...

I got one of those poly tranny mounts for the tranny-awesome. I got 4 bolts in it instead of 3. Its not going nowhere and its solid. Iv got just a few odds an ends to do on the 63 to get it started. Since its kinda cold im going to mess with the engine i pulled out of the 63 to put in the 70 c10. Im going to take the balancer and timing cover off an see if it has a double roll chain or not an if not get one an put it on and im going to take the oil pan off an see if its a 2 or 4 bolt and make sure the oil pump filter is on the pump an not in the bottom of the pan. Then im just going to put back together and clean it up and"paint" it(lol) an get it ready to be put in the 70 c10. The engine is just a stock 350/with 305 heads. I did a compression test on it before i pulled it out and it had low compression for a 350/305head comb.(130psi) not sure why? it did'nt burn oil-my guess is either they had put low compression pistions in it or used the wrong head gasket-not sure which one you would use anyone know? This is not going to be a hot rod motor. I firgure the 350/305 head combo should be a 9.2 to 1 combo which is about 160psi on a stock reg. 350 its 150 psi for a 8.5 to 1 motor and with the way it is at 130 psi im only getting at best 8 to 1. This engine was suppose to of been rebuilt a few years back so im thinking they put the wrong head gaskets on it---which head gaskets would you get for a 350/305 combo? 305? This is at best going to be a 5500rpm motor
