EAD 6816 A, M-42, ECG 6604 A & B (Were any of these stock on a '55 Thunderbird?) (Are the specs the same for the 6604 A & B?)

Have read a couple of posts regarding the gerotor vs spur-gear pumps.

What would be your choice?
Rebuild the aluminum (not steel as Ted seems to favor) gerator I have in stock, or. buy a new spur-gear pump for a 350hp Y-block, or?

For all the reasons stated in the link, the gerotor pump.

Brent.  The Forum archive link you referenced is a very complete reference for information to help you in deciding which oil pump to use on your engine build from a technical standpoint.

IF the engine you're putting together for your '55 is to be 'period correct', ALL '55 Ford y-blocks were produced with the gear drive oil pumps. 

The Classic Thunderbird Club International offers a manual to help in making your car as original as it was when it was produced 63 or 64 years ago.  Titled the 'C.T.C.I. Restoration & Specification Manual' it is made-up of 10 'Addendums' authored over the years 1995 - 2013.  The sections are labeled A - J and add up to 470  8 1/2 x 11 pages of technical information and color pictures.  Member cost for the manual and the binders to hold the 10 sections is $185 plus shipping.  A printable index for the manual contents is available on the C.T.C.I web site.

My copy of this manual is on loan to a friend who is restoring a D code '57, so I'm not able to reference the C.T.C.I. info provided about the gear pumps used on the '55 'Birds that you asked about.

Charlies, thank you for your advice. 

I will rebuild the one of the gerotor pumps (Are the specs the same for the 6604 A & B?) Having read the recent "Low idle oil pressure" post, I hope that Ted will mfg a kit to make the gerotor an HV, the specs are better from start to finish line.

I have the Restoration Manual (did not know about the index, THANKS for that.) There is no reference to correct oil pump ID. I'm guessing EAD 6816 A.

THANKS!!!

"EAD 6816 A, M-42, ECG 6604 A & B (Were any of these stock on a '55 Thunderbird?) (Are the specs the same for the 6604 A & B?)"

What you are seeing here are ENGINEERING PARTS NOS, or CASTING I.D. NOS. for the individual components.

The 6604 - A or B is most likely an engineering design change (B being the upgraded part).

To match component parts period correctly would involve a lot of research in a period correct CHASSIS CATALOG (the FINAL ISSUE MPC 49/59 has much original info deleted), SERVICE MANUALS and/or FACTORY SERVICE LETTERS.

Specs should be the same.

I doubt a high volume pump or conversion kit will be available since it's not really needed.  An engine in good condition will have good oil pressure.  An engine with issues may have low oil pressure.  The fix is to repair the engine, not to band-aid it with a hv pump.
That said, Ted has outlined how to do it in an article on his site.  If anyone wants to take on the project of bringing something to the market, the way to do it is known, tested, and proven.  Take the initiative to have the parts made and offer it for sale.  http://www.eatonbalancing.com/2014/09/19/hi-volume-oil-pump-for-the-y/

i agree with charley 100%
 it its very interesting how we improve oil flow to rockers which reduces cam load, increases rocker shafts and rocker life,then dump the gain down the tubes. i always dismantle oil pumps new  or not,tiny metal, or other degree from machining as well as assembly aria. remember the oil pump gets un filterd oil constantly. plus it is easey to remove the relief valve and check.also
new pumps are made where??. the tolerances can creep depending  on the makers acceptable limits.
so check the new pump, block the return tubes. just a canadian slant .
