68 charger 383 2 barrel Original timing chain and gears

[moparstuart]

Help  i have my 68 charger survivor 383  74 k miles  all original internals  , with its original timing chain and gears  , I understand the cheap bean counters put nylon teeth coating the gears   
   I have my radiator out being fixed im thinking about doing the timing chain also as its a ticking time bomb im sure , Luckily no nylon chunks in the oil pan as of yet yet .  My question is this .  Is there a way of telling what timing gear set I need without tearing the front of the motor down first ?    Its a April 1st 1968 St louis build car with a 383 2 barrel . I would love to order a double steel roller set of gears and chain for it and have it on hand before tearing it down the rest of the way .  Do i need single bolt cam gear or a three bolt cam gear . ?   thanks  in advanced for any insights and help     Stuart

Pull the dist, & get a mirror to see what the gear is made of, I have seen the 383 2bbl with a nylon one

im changing it  just need to know single bolt or 3 bolt  ,  I have now been told all 383's are a single bolt cam gear   440+6 and hemi are the only ones that got 3 bolt cam gear

Only the Hemi got 3-bolt sprockets.

I recently tore down the 383 from my 1968 Charger.  Single bolt, nylon teeth.  The nylon teeth were used for noise reasons.  It kept the engine a little quieter.  My engine was at 120,000 miles and the teeth were still intact.

I had a 318 duster , about 85,000 miles. Was running fine,  jumped time while cruising about 50 mph and bent a bunch of valves.  A friend had a 440 that clogged the oil pickup with nylon chunks and spun a bearing. IMO, any stock untouched vintage engine , regardless of mileage, should have that  "silent" timing set replaced.
