Just bought a 65 satellite convertible with a 426 super command and 727 automatic. I’m new to mopar. Anyone have the tune up specs on this engine. Believe it was restored stock. Thanks so much.

What are you running for carb and distributor? It should tune to the same spec's as a 440 Super Commando. I run 750cfm. Edelbrocks on both my 440's, and have found mine run better with one stage fatter metering rod in the primaries, and one step larger jet in the secondaries. I think your 426 only has a 625 cfm. AFB, like the 383 did.
Nice colour on your Satellite! A friend of mine has a hardtop the same colour.

Congrats! Post more when convenient
 
Pretty car ! I'll add that on every Mopar I've owned - that's a couple dozen at least - bumping up the initial timing to 10-12 degrees has made them more responsive.
