The problem is you can't run a late distributor/magneto off the timing cover and still run the early 37-48 water pumps and crank pulley. When they moved the distributor to the side in 49 - 53 they also changed the crank pulley and the water pumps (along with the timing cover cam/crank gears, etc). The later water pumps put the belts further away from the block - such that there is room for the belt to go by the distributor. You could make the front of the motor "act like a 49-53 - with the later crank pulley, water pumps, etc.. That is what Ronnie is talking about . . . but that brings in another whole set of issues (depending on the frame/year you're putting this into).

Also, you have to think about your generator and fan - your setup will not work with the belts being moved further forward (using the late F1 water pumps) - so there is another problem.

So, if you're putting all of this in a stock 32 frame, you just created a big problem --> the crankshaft pulley now wants to be in the middle of the front cross-member. Some folks "jacked their engines up" - but that looks like crap. So, if you're putting this in a 32-34 frame and want the engine in the stock location . . . you're kind of hosed. You really need to go back to a front-mount ignition (angle drive magneto, crab distributor, etc). There is no room for the later crankshaft pulley - with the engine in the correct location. Hell, there is barely room for a single-sheeve crankshaft pulley in the stock location!

Also, you probably don't want to move the engine back - then you have firewall and a host of other issues (think transmission location, clutch location, etc, etc, etc.).
