I am looking for references, pics, hop ups ect. for the Lincoln Zephyr FlatHead V12. Any help is appreciated. Thanks. Jody
you've taken on a major task - there's stuff out there, but it is few and far between, them old V12s ran smooth in their day, but the pistons are about the size of those portable V8 cans that come in a sixpack. I'm making this comment so your inquiry can be rotated back to the top, as I'm sure I've seen HAMBers reference someone on here that has a rodded V12, or know more about them than most. dj
Well, have not made any purchase yet. But I have a vission and want to do my research before committing! I think they look totally cool. I knnow I have seen a blue model A pickup somehweres with one with a blower on top. Just looked totally cool! Thanks. Jody
Hi im building one right now, there realy is not that many hop up for the v12, i think mine is done the best that can be done. here are my hop up's. ulum stock head's, edmond's duel carb intake with scripted Zephyr V-12 carb's, stock center dump ex. manafold's, i think these are a lot cooler and rarer than red's header's, winfield grind on the cam, ulum. piston's, stainless valve's, one piece valve guide's. that's the part's but there is certian block's you want and dist. there realy are a lot of trick's with the V12 so do your home work thay are verrrrrrrrry expensive to build. you can e mail me or call if you get more interested. thank's Chris
One of my neighbors has one in a Oakland roadster, runs smooth, sounds like 2 sixes running side by side.
I really don't know the engine,but here's a Lincoln V-12 Manual-not sure if it's your engine,,though. Any help? http://www.tocmp.com/manuals/engine/LincolnV12/index.htm
That manual is a necessity...covers all H series 12's '36--48. It is out in paper repro and originals are fairly common. A full set of Ford service bulletins contains a lot of Zephyr info; don't know if the repro ones carru the 12 cyl pages. There were also LZ only service bulletins. There is a Lincoln book by Ocee Rich with a LOT of info. I believe it may have contained a reprint of the engine overhaul book even. I can help you find some of this stuff.
Hi helmsville, Some Questions?: Lincoln V12 Deck height & rod length? Same as V8 Flathead?; 10-7/16" DH and 7.00" C/C length. Cylinder Bore C/C Spacing of the cylinders between the main bearing saddles? 1-3, 5-7, 9-11 etc. Factory P/N on the early 2-1/8" journal Connecting Rods & the later 2-1/4" journal connecting Rods? Or the rod bolt C/C spacing? Thanks for any Info on the above questions. Mac1
standard engine bores: '36 to '39 2-3/4": '40-'41 2-7/8"; '42 to early '46 2-15/16" ; '46 to '48 2-7/8". Crankshaft main journals , all engines 2.401" Crankshaft rod journals, '36 to '41 2.126"; '42 to '48 2.250" here is sum info, im sorry i dont know more, im kinda a check writer on this project, but i do know what kinda block's and part's you want to build. thank's Chris
The main caps for the V12 are not unique to the block. They were precision machined and supplied as a separate replacement item. Of course it's possible there could be some slight mis match at the rear main but unlikely. The machine shop has an adjustable bar that can check the alignment of the mains. I have found that if the thrust surfaces on the rear cap and block don't quite line up the cap can be "bumped" fore or aft slightly to get the proper end play in the crank. Cam bushings: The rear bushing is fairly long and should be installed with the 3/8" ( maybe a little bigger) hole at the top and aligned with the hole in the block for the fuel pump push rod. They can check this by slipping a 5/16" rod down thru the fuel pump bushing from the top. If they miss it a little they can run a 5/16" drill down thru to clean up any small mis match. The rest of the cam bushings should be installed with the oil hole DOWN, 6:00 position or no higher than the 7:00 position as viewed from the front. The idea ( not mine but Lincoln's) is to keep the cam firmly against the hole holes as the bushings are somewhat sacrificial and as they wear excess oil leakage won't drop oil pressure. The cam bushings are first in line after the rear main to receive oil from the system. I would prefer that they did not install the front ( #1) cam bushing as I have to drill a hole down thru the front relief passage into the groove that surrounds the bushing. This has to be done in order to supply oil to the camshaft gear. We will be eliminating the original source for this with the use of adjustable tappets and the feed lines for the hydraulic lifters are plugged. The Machine shop may want check the end play fit of the rear main bearing? It should be .002" to .006" and not more than .008". I had to dress down the rear bearing thrust surface on one of my engines but the other was dead on. They will be able to do this check when the undersize to be ground on the crank is known and you've ordered and received your bearings. here is some more info i hope this help's
What a timing; Just sold one yesterday.. have another one laying around, considering what to do with it. Both of the ones I have are mid year '46 that by the look of it have never been apart. If you need pictures of any "from the factory" items, let me know.. I can get them pretty easily starting next week. This is the one I sold yesterday: http://www.jalopyjournal.com/forum/showthread.php?t=333099
Check out this link . It may well be the car you are thinking about. It is owned/built by well known Australian rodder Rod Hadfield. http://www.rarespareslegend.com.au/Legends/rod-hadfield-cars/rat-rod.jpg
