Correct, the pump pulleys were offset. The pump shafts are the same length but different pulleys. And thank you... Vergil
The Ford truck mounts also used a center mount under the crank pulley to bear most of the engine load. The waterpump mounting surfaces are not very thick on the flathead and I think the water pump mounts were mainly used to steady the engine. I made bell housing mounts to share the load as I omitted the center mount. Flatman
from memory , did this a fair while ago but the valley without intake on i think and dont hold me to this was about 10 degrees down to rear its not a big amount but a little, ill check with my bro whom is on here too and get back to you soon with exact amount pretty sure it was 10 degrees, we used a degree meter whilst doing it, im sure theres guys out there that dont do it but, its the way ive been taught and my predecessors before them at same time im not saying this is the only way to do it and im not saying its right or wrong just how i did it
yes i forgot to say, my friend machined my harmonic down to run a single belt, to run pumps and gen ,still wide belt,, as far as fan goes ill be running an elec thermo one off a switch in which ill be taking out of the shroud it has on it, run it in stock fan position via a bracket ill make , its a 4 blade looks like an old fan, less inertia on engine which always equals more power, my brother did it on his a and you need to look close to see its not the real thing, its black and fits well, yes i know there will be people that dont agree with doing this but its easy and works and looks good
you probably won't want the merc pumps--they do mount the engine lower and are expensive. sometimes with a later flatty in an earlier chassis, you may even have to put shims under the motor mounts for oil pan clearance.
