One thing I learned a long long time ago about those spiral wound looking flex hoses,....when you try to make them conform to unusual twists, bends and turns between head outlets and radiator tank inlets, they will cause an undo strain at the soldered junction of tubes to tank, and could cause a failure, and usually at the most inopportune time. I would never recommend that anyone use them.

Found it: Gates 21253 used in conjunction with a NAPA hose adapter 902. Flex hoses are criminal.

Larry, no need to change location or position of top radiator inlet tubes on 35/36 when installing a 37-48 FH engine with center outlet heads. Here is one of many posts on Fordbarn on this topic. If you do a search there for "gates hose" or "gates top radiator hose" these posts will be found that include all the information you need. http://www.fordbarn.com/forum/showthread.php?t=157291&highlight=gates+hose&showall=1 John

If you're converting to the flex-hose option to connect to the 37 heads, are you also changing the outlets at the top of the 36 radiator (the originals point downward at a sharp angle to connect to the original water pumps at the front of the cylinder heads)? I have a 59 engine in my 36 and I had the radiator outlets altered to point back level to the ground, so the flex hoses loop gently back to the inlets at the center of the engine. It works fine. Without the change the hoses would have had to make two sharp turns, first down one direction, then back, then down n another direction, before they connected to the engine; I didn't want to do that.

I am currently doing this exact conversion. Can anyone provide the Gates hose number for me? Thanks: Arnie

Those funky looking flex hoses were never a good thing to use when putting a 37 to 48 flathead engine in an earlier 32 to 36 V8 Ford. Gates makes an upper hose that works perfectly for this conversion. Also, Drake is now offering their hose kits for this conversion.

I think more to the question of which heads to use, your options are to use funky looking flex hoses on the '37 heads, or to use the '36 heads with correct hoses. ...This, of course, due to the different location of the outlets, center on '37, and front on '36.

Another plus for a '37 block is the cylinder wall thickness is greater than the earlier 21 stud blocks. The original bore of 3-1/16" can usually be safely increased to 3-3/16". Maybe add a 4" Merc crankshaft and a few other performance enhancing items, and you can have a little power house engine in the same league as the later 24 stud engines.

Hi Everyone, I'm a noob, and this just my opinion but... 1937 Block with pumps in block, very nice, inserts and cooling. 1937 Block with pumps in heads, nice, inserts. Owner of 1936 Phaeton with pre-37 replacement block. 1935 Fordor with post-36 block. And a spare 37-ish. -VT/JeffH club site WWW.NCR36.COM
