What mileage does your slant six powered ride get?

If you are getting 21 under those conditions you are doing great. Hop in that thing and drive 55-60 for a 4 hour round trip then get back with us. I bet you'll see 25 or so. Your mileage is not ''highway".

Yeah, I'd like to but I've nowhere to go that is far enough! I'd like to do the same for the Coronet for that matter ... (318, but still a 2.7X rear and I get 12.5 to 16 for the same work commute as the Valiant's 13-15. But I've never had a chance to do a long, highway trip with that car)

I think Valiant's timing is 5* BTDC? But I have no idea what rpm it was idling at...
