its kinda heavy so im thinkin cast aluminum but maybe not...
any yes, the only difference between this dizzy (desides maybe curve) is that it had the "port" for the mech tach drive, otherwise its just a chrylser electronic dizzy
but it is a factory peice
Good deal bump! The mechanical tach drive race units are very nice with quick curve. The cap & rotor are slightly different from other Mopar distributors though. Need Part #4120886 which Jims & a few others carry.

hi, it's made out of cast iron, later models were aluminum. having a cable made, ask for tach cable, not speedo cable. tach cable is left hand, speedo is right hand. it will unwind after a while. been there and seen that.

My research shows this cap #4120886 comes on the MP electronic Vacumn advance dizzy SB units sold new, isn't that the same as most other caps?
The vacumn advance dizzy(3690430) uses cap#5007856. The older mechanical tach dizzy has larger & higher cap clamps and needs #4120886. Don't think mopar performance even carries this cap anymore since they just have billet unit still available, so ones out there are left in vendors inventory. Here is a pic of the difference. Picture sucks but regular#5007856 cap is on left & one you need is on right. Can also notice difference in picture from Jims catalog.
