Distributor question

i have used new nylon when i was doing something planned

i have used any old dizzy with anu old gear nylon gear when i have been pressed into it due to circumstance ie sending off my good (unique to this motor) dizzys for recondition and recurve i ran on aold points one as found for about a year

still not had a problem

the only place i have heard of a problem with nylon gears is in the sales pitch for a brass gear

never say never you might get a bad one or a sub standard one and i might just have been lucky

they will eventually get pickled in oil nasty old oil, they look like they are old and stained and they get a little bit more brittle BUT i'm talking 50 years old...... that's good going for a car and motor that the manufacturer expected to be made into bean cans somewhere between year 7 and year 10

on mine it is for the vibration in the cam. there is a harmonic nodal point in the middle. Dizzy is sited in a gap between it a and the second nodal point, below cylinder 5 , hence my dizzy at cylinder 5 and yours nominally at cylinder 2. not in the middle...! they thought about where to put it

on yours possibly less of a vibration worry, less distance to flex between the cam drive and your dizzy gear. but chrysler in general thought about their engineering in a way that some of the others did not

and we are talking small torsional twists in the cam, putting vibration into the dizzy shaft, like its shivering, as the valve springs alternately load up and unload and the clover leave impeller in you oil pump is in the "entrance closed"- "exit closed" millisecond between each "pump"

on high output hemi 6s some run nylon blocks in the cam area to act as support or damper of cam vibration and flex. you would not be likely to be running your slant at 7000 rpm so would never need the kinda spring that causes that much flex.
