Billy zz,
Glad to hear you are making progress, I know the problem of more time than money, and I wish I had more time.

Nah. You can call me that. Or just J. Or Jim...

Anyway, I don't think my son has ever checked the mileage on his sedan, but my coupe gets about 18.5 on the road. Probably 16 or so around town. It's not great mileage, but I've had worse. My engine is a .030 over 350 with hypereutectic flat top pistons and some old open chamber (76 cc) LT-1 heads (1.94/1.60 valves). Intake is Edelbrock Torker II with an old Quadra-jet carb. The cam is a Crane Energizer. I don't remember the specs on it, but it was the most radical cam I could use and still keep the stock torque converter. The transmission is a bone stock Turbo 350 out of an early 70s Monte Carlo and the ignition is an old fashioned points/coil distributor.

Probably, if I put a dual plane manifold on it with a freshly rebuilt carb, HEI ignition and maybe a different cam, I could boost the mileage some...

Your chevy truck is coming along great. Always liked the early chevy and with what you had to start with, you've come along way. I'm running 2:76 in my 9" ford rear and get aroung 21 MPG. After I had the heads reworked the engine breath alot better and my mileage went from 16 to 21. Even with the work done on the little 305 that's putting out 303 HP and 313 lbs of torque, Cannot spin the wheels with those high gears Fogure I save on money for tires using those gears, because if I some 3:55 in there, I d probably go thru 2 sets in one summer

Looking good. Nice to see a Chevy of that vintage. Did that one have alot of wood? Always heard that gm used more wood than ford. I'll be watching this one. I've gotten to almost like the trucks over the cars..........

the skeleton was ALL wood.
i got about 70 feet of 1" tubing and maybe 10 feet of 2"
in that cab.
it was built like a horse drawn carriage
lots and lots of tiny tacks and wood screws.
