Matt Harwood Posted November 16, 2005 Share Posted November 16, 2005 The '50 block won't work because of the side-mounted engine mounts on the later engine, but the guts will fit in your existing '41 block. It might be easier to simply rebuild what you have rather than try to build a hybrid. A good machine shop could machine your existing parts to use insert type bearings, which is what I plan to do on my '41 66S. Link to comment Share on other sites More sharing options...
jerry burger Posted November 16, 2005 Share Posted November 16, 2005 the rods in the 50 engine are insert type and will drop in your 41 as is.i did this conversion on my 41 century and it is a natural.you can get nos bearings from different suppliers.allmost everything on the 50 engine will work on the 41.mr harwood is right about the mounts.make sure your head is flat when you get it off,i had to mill mine 0040.if you mill the head shim the rocker arm stands 1/2 the amount taken off the head as the milling will change the angle of the rocker arms.

critterpainter Posted November 27, 2005 Share Posted November 27, 2005 Actually the engine will fit if you use the front timing plate from your 41 to attach the motor mounts to. If the 50 engine is froma dynaflow you will have issues with the flywheel as the rear of the crank is different on the two engines. Also the later engine will have hyd lifters.

The Old Guy Posted November 27, 2005 Share Posted November 27, 2005 If you plan on running the dual carb system, you will also experience a clearance problem ,unless you use the fron mount from your 41 Link to comment Share on other sites More sharing options...
