3:55 gears on the street

Exactly! 60/65, I’m good, no rush. I’ve done 70/75 and the secondary side tends to tip in. Not good for mileage. It takes a nose dive when the secondary side starts feeding the engine! LMAO!!!

At the time, I had a smog era ‘78-400 B engine in it. 60 mph and 18 mpg’s, yea! I’m good with that!
Go to 75 mph, mileage tanks!
