37 engine in 34 truck
My 1934 BB large truck has a 1937 engine in it. What is the best way to correct the engine height and lower radiator hose alignment?
Honest Charlie's lists a cast swan neck to fit lower hoses and one of the other suppliers lists S shaped hose for the lower. Any thoughts? Also some list different engine mounts or risers for them. After doing this will the radiator crank hole line up with the crank pulley? Looks like I will have to pull the engine for some internal work so just trying to think ahead for parts and ideas. Thanks, John. |

Re: 37 engine in 34 truck
easy would be to run block water plates and early engine mounts, heads and water pumps.
both are 21 stud. but you are already there? great replacement block for early flatheads. everything 21 but with inserts and cam bearings. . Last edited by Tinker; 09-10-2019 at 01:35 AM. |

Another option would be to keep the '37-'48 water pumps with Merc "U" shapped spacers between pump mount and frame.

Re: 37 engine in 34 truck
I have found that motor mount spacers can be easily made with a couple of chunks of 1/8" wall 2" square tube and a couple of proper sized bolts if you have a hacksaw, drill, and a welder. (The welder is optional). I like them better than the "U-shaped" ones, myself.

Re: 37 engine in 34 truck
There are spacers made for this application, including the original ones Ford used when installing a later replacement block in the early frame. It is more than a height issue, the side to side spacing is different as well.

Re: 37 engine in 34 truck
JSeery I think your answer is what should have been done many years ago, likely the 60's, when the 37 or newer engine was put in.
The previous owner used metal spacers with a long bolt thru everything. This is going to be just the tip of the iceberg as I got the engine freed up today and find the #3 rod is not attached to the crank. Now to pull the engine. The engine has the crab style distributor on it. A friend has a good 49 flathead with upright dist. Will the 49 engine fit and work with the BB's trans? Thanks again this is going to be a long project. |

[QUOTE...haven't posted in a long long time....[/QUOTE]
That's an understatement. Hope all is well with ya and yours. To the thread poster... I'd think about getting rid of the 4sp truck transmission if you are doing a later swap. Less that's what you want. Save the motor you pull. Sounds like it is useful to someone. at least there is some great parts there. . Last edited by Tinker; 09-10-2019 at 08:49 PM. |

Re: 37 engine in 34 truck
not mentioned yet, if you use the later water pumps and motor mount brackets as jseary shows, you will then use later 8ba lower radiator hoses which have a slight curve to get you over the cross member and into the radiator. try to get the height to match the crank hole if you make your own mounts

Re: 37 engine in 34 truck
Well things just changed a bit. After cleaning the engine and heads I find that I have a 59 block with 59a and 59ab heads. So does that make this a 1946 engine? The truck still has the original 4spd trans with matching chassis number BB18-513999. It is set up as a single wide belt engine, fan on the end of the generator, crab style distributor. How in the dickens do you get the lower bolt out of the water pumps with it inside the lower hose flange? This is my first Ford flathead and I am confused as to what years all the parts are and what will interchange. Thanks for the help and understanding.

Re: 37 engine in 34 truck
Lower pump bolt. Good quality six sided 9/16" socket, or a 14mm knocked on if a bit undersize.
