OK thanks Jeff. Would really like to see a few photos as I am painting the bell housing now as I did not paint it on the motor, but will try to simulate. I was surprised at how little paint actually was applied to the bell housing. I tried searching the Library but did not find a good bell housing photo.
Don't have any original examples from a 428 CJ but from other Fe's they had allot of paint likely due to the high pressure and flow guns used at the time very unlike to days paint guns. So IMHO would go wide and will allot more "soft"/thin overspray on much of the bellhousing with shadows in those surfaces point downward and rearward, base don the ones I've seen. You will notice this on the upper left example below more than the lower right example
Of course ANY cleaning or scrubbing to other examples would remove this lighter spray reducing the painted area on those examples
Couple of examples and its pretty clear that these have not been repainted since the original crayon markings are still evident
