Flathead dodge 6 ????

Hi all, I have a 1950 Dodge Wayfarer Bizz coupe. The motor is a flathead 6 230 (23 inch long head) I have a chance to buy a rebuilt flat 6 for a song. But it is the 25 inch long head. what I would like to know is will it fit and bolt rite up? oh ya they are bolth fluid drive trannys.
thanks

 

If I remember 1958 well enough it was a near bolt in. My exhaust head pipe was different and I should have moved the crossover brake line on top of the front crossmember as the front mount sat right down on it and squashed it. Move it first. All these years and I still remember looking at what I had done to that tube and feeling really dumb.
