HOLLEY Mech. Fuel Pumps ?

Ok guys I don't know if this will do any good but I just E-Mailed Holley's Fuel pump Dept. and asked (or should I say told) them that the Buick community needs a quality aftermarket mech.fuel pump to supply our perfomance needs.I'm sure they already know that Carter no longer makes a "high performance" pump for the Buick 350 so maybe if we keep bugging them they'll get the hint and cover our end of the muscle car market .The only way though is for people to let them know that the Buick #'s are there and that there could be a viable market for them.So let them hear your opinion and let's see if we can have an influence on them and get some more performance parts on the market for our 350's. :TU: Jeff Bullock

 

Sorry, but I don't think that they'll do it.

This is because, like Carter, they used to offer one. I had one for years and recently sold it.

Are you sure that a good stock pump won't cut it?

 

It seems like since I put in the TA 212 , the engine wants to run strong and pull hard up to @ 4600-4800 rpm but then it seems like it could use just a little more fuel. This could also be due to the fact I only have an Edelbrock 600 cfm carb on it. With the ported heads, it's probably not getting enough in the bowls not to mention the lack of sufficient air flow the smaller venturi of the #1406 Edelbrocko No: I have heard different theories but didn't think it would hurt to run a little more pressure and volume to the carb first to see if that would make an improvement before I bought a bigger carb like a 750 or 800 cfm Edelbrock or a rebuilt and specd. quadrajet.Figure I would try to start cheap:grin:

 

Jeff, I think your carb is the problem. A lot of guys are running pretty stout motors with a good AC Delco pump.

 

Well its not a Buick but I had a 89 Formula 350 with a pretty hot small block that ran 12.50's @ 107-108 that used a Edelbrock 600 with no problems. I first used a Edelbrock 750 on it and it ran 12.50's but had a stumble on the tip in so I borrowed my buddies 600 to make sure the prob was in the carb and it ran great. My car ran about .04 and almost 1 mph faster with the 750 than it did with the 600 but the idle qaulity and transition was much better. My conclusion was that my 350 didn't need the more CFM's. It was a 350(Chevy, I know Iknow) with a Lunait roller cam with 281 adv. duration and it had Dart II heads and a Performer RPM intake. The car weighed #3700 and used a 3.50 gear. Have you tried rejetting your carb? Steve

 

I haven't tried yet as that is an area I'm just learning about. I know how to , just need to figure out if I need to go up or down.:grin:

 

my gettup is pretty simaliar to your's except for TA intake, and a "performance" q-jet. The q-jet is remanufactured by JET. I don't think they really did much to it tho. Anyway, mine will pull hard up to 6k. But it does seem to pull better if I have it in first gear and hit the go pedal at about 35, than if I'm on it from the floor. So maybe it is running out of juice. I am running a stock replacement pump.

 

another thought- It is rumored that a stock HEI ignitions start going weak up above 4500. I don't know about points, but... maybe a MSD might help out, that's what I run.

 

I've thought about the ignition also.Currently it is just a HEI w/Accel Supercoil and plugs gapped at .040 .I asked at one time about a high performance module and most guys told me they were over rated.But if I do decide to get one it will be the GM version as they are the same as proforms and Accels plus they're about $10-$15 cheaper.

 

.040 Why such a small gap. With HEI and that coil I would think you could widen the gap a little. Just from my experiance with chevys though.

 

I ran .030 with the points set-up and when I switched to the HEI I was told to not go more than .040 with the Accel supercoil.o No: You know what they say about opinions.ou:

 

I believe stock HEI plugs are gapped at .060.... best bet for plugs is to get some for a 77 engine, that way you will know that they are correct for HEI. but make sure to get a good heat range. The ones the parts guy gave me are a 10 out of 10 heat range. On a modified enigine that will cause pinging and detonation, which I have... I put some cooler plugs in yesterday, once the roads clear up a bit I'll go for a test drive, see if they helped. Had a little snow storm yesterday...

 

well running cooler plugs didn't change anything. Still pings at part throttle, and keeps running a bit after I shut off the key... my timing is set pretty low too, about 6-8 intitial, and 32 total or so... with the vacuum advance limited, but it may be coming on too early.... Hopefully tommarow I'll get an O2 sensor in there for my A/F gauge, maybe I'm running a little lean. I had one in there on my head pipes, but when I put the headers on I didn't put the O2 sensor back in.

 

Are you running the TA 212 in this engine that your talking about?If so, you should try advancing your timing about 4-5 degrees and see what that does.I run 18* initial on mine and it takes right off without a bog or anything.You could possibly go even higher than 4* or5*.Just have to experiment and see what works. :TU: If you still have the original balancer on there it could be off by a couple degrees also.I would at least try it at 12*-14* to start with and go up or down a couple degrees at a timeo No:

 

how much mechanical advance should a stock HEI give?
