I don't think I've ever laid a wrench on a slant 6 so know nothing about them. There's more than one size, apparently? How do you tell the sizes? damper difference, distributor location, etc.? Where would the 'numbers' be on one? Thanks!

If it helps, this motor is in '63 Dodge 330 w/a 3spd stick. Thanks!




the engines are basically the same other than the 170 and 190 have a shorter hose from water pump to head.
its very easy to discern the diff of 225 from the other two by standing by battery and looking across at the water pump hose that runs up to the head . on the 225 the little hose is about 4 inches long where as the 170 190 the hose is about 2 " long
