1995 360 Mechanical Fuel Pump Suggestion

1995 360 Mechanical Fuel Pump Suggestion - 09/17/12 02:17 AM

It will be in a street/strip car and I need to adapt it to a 6 AN. Mild 95 360 roller engine in the car now. I was leaning towards this....

Any feedback?

Suggestions?

Thanks in advance,
Brian

I ran one on my 70' 340 Duster 8.20's in the 1/8 mile with no problems
Drove it to work everyday

Did you run any type of pressure regulator? Anybody else using one?

Re: 1995 360 Mechanical Fuel Pump Suggestion - 09/25/12 08:16 PM

That pump may need a regulator. If you do not want to use a regulator, try the Carter Super Mechanical M6902. I just put one on my 340 a few weeks ago and it puts out 7psi and no need for a regulator with my carb.

Forget mechanical, put a Carter street Pump, P4070, back near the fuel tank. Run it off a switched power source. No regulator needed.

the 95 360 is a magnum engine correct?

are you going to run a LA pre-magnum t-cover to mount a mech FP?

remember to order a long nose roller cam to fit the FP eccentric on the cam.

or an adaptor for a short nose cam from Hughes.

Hey Scratch what's up?

I'm not sure what all of that means?

What Mike is talking about is this:
Stock Mag cam doesn't have the extension for the fuel pump eccentric
Hughes sells a kit to put that eccentric on
You can get aftermarket cams with or without the extension made on

I used a return style regulator

Re: 1995 360 Mechanical Fuel Pump Suggestion - 09/26/12 06:27 PM

Carter Street Pump doesn't need a regulator or a return line. Its output is something like 4-5 psi.

The Carter pump that I used was the same pump used in NASCAR & was one the was used by the King himself on one of his Magnums in the late 70's

Any idea how to find out if this cam is set up for a mechanical fuel pump?

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/06/12 11:45 AM

I have a stock short nose roller cam on the shelf,i will measure the nose and you can see if yours is longer or same.

I orderd my lunati voodoo roller cam with the long nose when I went roller cam.

if it is short you can get the adaptor from hughes to run the ecentric for mech pump.

im wondering this also,without pulling intake.can you look into the fuel pump block off plate to see?

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/08/12 02:17 AM

The engine builder got back to me and said he usually puts an eccentric on for mechanical pump use. Is there a way to pull the fuel pump plate off and check? If so what am I looking for?

Posted By: scratchnfotraction

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/08/12 02:52 AM

on a short nose cam it will have the t-gear and a different style washer/bolt.

if it has the ecentric,you should see it in front of the t-gear looking into the fp hole.

IIRC a magnum has a thinner t-cover and this is why a fp ecentric will not fit behind the mag cover.

but by using a pre-magnum t-cover and the hughes fp adaptor you can run an ecentric on the short nose cam.

if the roller cam pre-mag engine had a carb it had a long nose roller cam for fp ecentric. if it was TBI it had the short nose roller cam with no ecentric but still had room in the t-cover for it. pre-mag TBI t-cover got a fp block off plate.

the pre-mag roller cams,short or long, will have the bearing journal drill for oil the rockers thru the heads.

a magnum roller cam will not. and it can not be used in a pre-mag LA engine block.

here is a pic of the short roller cam nose with a tape mearsure for referance.

make note of the flat t-gear washer and bolt. this is different from the ecentric and its own washer/bolt.

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/08/12 02:58 AM

if you look in the first pic with the bolt washer turned in. there is no room for the thickness of the ecentric to fit.

the key way is flush in the t-gear with the flat washer.

on a long nose the keyway is sticking out to go in the keyway of the ecentric. with a bell type washer/bolt.

do you have a part# for that cam?

I have a mopar catalog I can look the specs up.

yes you can see the ecentric in place thru the FP hole.

4 things I would want to know.

1)is it a long or short nose roller cam?

2) is it drilled to oil thru head to the shaft rockers?

3) are the roller lifters oil thru style with hollow PRs?

(they can use solid PRs also but good to know what you have.)

*** 4) did they drill the 95 block to oil thru the heads to the shaft mount rockers??

magnum blocks are not drilled for LA style oiling when running pre-mag heads.

Scratch,

As far as the oiling, I checked that last July:

https://board.moparts.org/ubbthreads/show...rue#Post6707768

You were actually helping me back then also. Here is the thread where I checked the oiling with by priming:

https://board.moparts.org/ubbthreads/show...rue#Post6810115

You also helped when he snapped that bolt off in the trans case.

Anyways I will have to try and find out if it is a long nose or short nose roller cam. I will email the builder and get back to you guys.

I appreciate the help, this has been going on for a long time. Its my brothers car and he has had it for about 9 years, he also just became a father. So with the busy schedule of being a new parent and then all of my stuff I have going on, we are wayyyy behind schedule.

Thanks to all, I appreciate the help

What does the ecentric actually look like when I look in the fuel pump hole? What am I looking for?

Thanks,
Brian

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/11/12 06:01 PM

He just got back to me and stated that it should be a long nose.

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/14/12 11:46 PM

I was able to pull off the block off plate today and this is what I am working with:

What do you guys think?

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/15/12 12:19 AM

i think bolt a fuel pump on and good to go.

that is INDEED the fuel pump ecentric.

if the arm on the FP wants to hold you up on the bolt aline ment,rotate the engine and roll the ecentric to the far side and pressure of the pump stroke.

Sweet!!!!!! So I am assuming that the eccentric is lobed? How else would it move the pump arm?

Re: 1995 360 Mechanical Fuel Pump Suggestion - 10/15/12 01:30 PM

it has a offset from the center bolt so as it spins it pushes down on the fp arm then let it come back up for the pump action.

Thanks to everyone for the help guys!!! Especially Scratch once again for always being there to answer about stuff. I have a Carter Super Mechanical M6902 on order and can now hopefully move forward a few more steps.

I was told that the MP camshafts all had long snouts for an eccentric. I also was told all MP crate engines had an eccentric on them.
