Anyone know of a good high volume fuel pump that mounts in the stock location with Edelbrock heads? I like the RobbMc 1100 pump but it won't clear the Edelbrock heads...anything similar that will?

There is no fuel pump at this time. Your best bet is to clearance the head and then have the hole re-welded. In order for the pump to fit you have to grind the head of which you will hit water, so you have to weld the hole.
Now if you have a 455, you should have no problems.

On my 455, I am running a Carter muscle car pump. However, I still had to carefully file a little off the head.

I'm running the same Carter pump and I didn't have to do any clearancing. The rubber diaphragm touches the head but there's no metal to metal contact.

Did your stock prebent hard line's hook up to this pump or do you have to rig in rubber line's? What does a stock off the shelf pump push for gpm?

442_Mustang

I ran AN fittings and braided line on mine. Wasn't going for the "Stock" look in my engine department.

507OLDS

In the works,but only one is being tested so far.I am installing another one on a car shortly.It will clear anything,and has AN fittings. So far so good.

Just my opinion, but Electric!!!! I have a buddy with an engine very similar to yours in a 70 442. He fought the Fuel Pimp issue for over a year, and just last month we stepped up to Electric with -6AN lines. What a Difference!!! The car even had a better sound at idle.

On a side note, his car with 3.23 and only 2200 Converter went 12.21 through Mufflers on Mickey T Sportsman Pros. More stall and slicks and I can see him in mid 11. range and he drives this car to the track!! Weight is 3900.

Keep me posted on your progress

Brian, I am interested. I just need it to support a fairly built 455 w/ ported Eddy's...I didn't want to go the electric route because I don't want to build a whole fuel system. I would like to come off the 3/8 steel line w/ a -AN hose to pump and then another pump to carb.

And I am not about to grind anything off of a $1700 set of heads that have had another $750 CNC port done...as Rodney Carrington would say "Dream on Hooker! Dream the F%^K on!"

ah64pilot

What do you mean if I have a 455 I should have no problems? I do have a 455 and have not found any mech pump that excludes Edelbrock heads.

64Rocket

My bad. I assume it was a 350 Olds.

So are you saying there is no problem running a mechanical pump on 455 w/ Eddy's?

442_Mustang

As I said, I have a 455 with Edelbrock heads and a Carter mech. fuel pump and it works fine. No clearancing was done.

ah64pilot

Do you think the Carter mech pump will support an All Out Port job done on the Edelbrocks? Our engines are pretty much the same with the exception of mine having flat top pistons and ported heads.

507OLDS

The Carter,Edelbrock,Holley,or Mr Gasket is not going to feed much more than a stock AC Delco pump.
I run an electric pump myself,but there are certain applications,as well as other people in the Oldsmobile community,that want a hi-volume mechanical pump.
The only true mechanical performance pump on the market right now,is the RobbMc pump.The problem with that pump is the large diameter body.It barely clears iron heads,and the only way it will clear an E-brock headed big block,is if you grind or machine a pocket in the head,which puts you close,if not,into the water jacket.The issues are worse with a small block.
The new pump will clear anything on a big block or small block.The 2 prototypes are both on E-brock headed engines.

ah64pilot

Brian I'll pay to test one for you...check pm.

442_Mustang

I havn't ran mine at the strip but i have taken a few blasts to well over 120 and I havn't noticed it falling over... I don't have a fuel pressure gauge so i dunno if it's on the edge.

507OLDS

Run it at the track & find out.If the engine is pretty healthy,you'll starve it at the top end.

442_Mustang

It dynoed at 479 hp/. 540 tq. We are hoping to do a strip run some time this year. Hopefully winter won't last forever.

Street tests often do not give an accurate check of how the fuel system is feeding the Engine. At the Strip, you would normally be doing a Burn-out of some duration then staging and launching...my experience has been that by the top of Second gear, or into 3rd if you have deep enough gears, the carb starts to run out of fuel...this is with any moderate to high-perf 455 on a Mechanical Pump. Besides the obvious aggravation, the dangerous part is leaning out the Engine and possible damage to your engine.

I am just spaeking from my own experience, but it seems to me that taking a chance with a new $11,000.00 Bullet is risky.

Again I am not preaching, but I have seen the difference first hand between Mech. and even the lowest price Summit Electric.

I have a 455 and Edelbrocks, and my Airtek 40736 mechanical hit the head on the rim of the pump, so I dented rim in gently there, just a tad for clearance.

A trick we used and worked in the 70s and 80s and so on was to put a Holley red or blue pump back by the gas tank to feed the mechanical pump. One of the secrets is most electric pumps you can pull gas right through them, with them off. So you should be able to drive it around with it off, and throw the switch, if you are about to get serious. The Holleys are loud, but using some thick rubber when you mount it can quieten them down a lot. I even used old style rubber faucet gaskets on the bolts or screws mounting them before on the frame.
