Don`t laugh at the civic on my trailer(11.20 car my son built), but i tow to the track with my 70 panel and my 67 GMC all the time. CRAZY looks on the highway too. My panel has an old 305 TPI w/7004r from a 89 camaro. 15-16 MPG regular driving, little under powered with my Monte on the trailer behind it, but gets albout 12mpg towing. Haven`t towed yet with my GMC since the 6.2 LS swap, but its way better on gas then the old 350 4/bbl 700r4 combo. Can`t figure out accurate mileage until i have a working odometer, lol, hoping Santa brings me some electronic gauges.
