That Summit link looks more like a Pertronix unit - Large size and screw on type distributor cap



The nice thing about the Firecore distributors , size , they accept factory style type distributor caps

I run the vacuum advance , non rtr on my 383 HP


Anyways around a year ago I ordered a Firecore RTR from Summit under there brand - They sent me an email saying they have been discontinued

I don’t see them at Mancini also

I see the Firecore standard vacuum , and Firecore racing mechanical , non rtr


Picture of Firecore RTR
