Anyone use one in a K-member car ? Big block is my concern here.

It would likely have to be mounted approximately where the original pump goes, lower left of engine.

I don't doubt that they do their job, I'm interested in mounting and clearance issues.
Photos would be excellent if you can.

I've used a belt drive oil pump on the dyno, never tried to fit one in a car though.

I run a Moroso external oil pump on my R3 small block.

The engine is apart right now but I probably can find some photos if you think they might help you.

I have a stock k frame and stock steering.

Lots of volume and pressure, I put a smaller pully on it and the "lower" pressure spring.

340Cuda, yes your pictures probably would be helpful.
Is there a power steering pump also ? That would be crowded.

You'd definately have to get rid of the steering box !!

I can't see the point other than a dry sump. Stock style pumps move plenty of oil - no issues there. Presumably you'd still be feeding the block at the same point so nothing to be gained there either.

Stanton, you can change drive pulley ratio, but one big advantage to me is no abnormal wear
on cam gear and pump drive gear.

Cam gear wear can be greatly minimized with a very thin machined washer between the gear and the bushing. The majority of wear is cause by the contact of "similar metals" - the bronze gear and the bronze bushing. Once they start to wear the gear now starts to move up and down and that causes the wear on the gear teeth. Put an .030 machined washer in there (commonly used with torrington bearings and wear will be ZERO. You could also use one of the "coated" gears being offered by various sources.

No power steering or alternator but a vacuum pump.

Several are on the engine stand, prepping the engine for a trip to the dyno. One shot is of a Peterson "Wet Vac" pump that would have combined the oil and the vacuum pump. It mounted nicely on the block but hit the steering box.

Let me know if I can be of any help,
Bill

Thank you, that is helpful.
I may or may not go with an engine plate, but the K-member
will be there. Manual steering.

what do you call abnormal wear? you have the dizzy on one end & an oil pump on the other, they kinda balance themselves out. Have never seen or heard of anyone saying their cam gear has worn away.

I think he's referring more to the wear of the oil pump drive gear and bushing.

As said already.. put a hard washer in there or a torrinton bearing in there

But we're in the race section here, so it's not like we're going to drive a zillion miles on these motors, race engine parts get checked at freshen up time & a new gear for the intermediate shaft has to be way cheaper than a remote pump.

I don't know what the OP is doing with his engine but I liked having a belt driven oil pump on that 470 engine I built. That engine was all belt drive. Belt drive cam, belt drive distributor and belt drive oil pump. Worked great.

Engine is getting a roller cam.

It can't be possible that everyone has forgotten about roller cam gear/pump drive gear failures, can it ?

Please reread my original post.

How many failures have you heard about vs the number of engines that run the same set up.. I an sure
way more run the set up vs what you heard about

I don't believe there is a commercially available mount bracket available, (unless Andy F lists one) it's not a particlarly common conversion. A friend of mine was talked in to it, a whole lot of expense for very little benefit really.
He had an ATI dampener with a BBC front pattern, could run an off the shelf drive kit, rather than me having to machine one. I had to make the block off/inlet plate to go to the block in place of the factory oil pump.
His engine is going on to a chassis car, so I can't comment on whether it will clear the K frame.

If your main reason for an external pump is gear wear, I suggest you re-read the very first reply after your bringing up the issue. Surely this can’t be the first time you’ve heard how to set up a roller cam pump drive.?.?.?.

Any more information or pics on this mod ? I'm interested since I seen some wear on my roller cam setup and in the process of installing a new bushing and would like to make a permanent fix.
