I will throw this in. I wanted a driver car for cruising and long trips. So I built a 4380 Lb. 1970 Nomad Sta. Wgn. Here is my driveline and results.
The engine is a very mild 468 with a Q-Jet, ( like a LS-5 or less) Tranny is a 700R4, Rear is a 69-12 bolt with a 3:07 rear gear, tires are 225 X 70R X 14" red lines.
The two ton wagon will burn the tires down to the 70-SS wheels if you stay in it from a dead stop. The wagon will cruise on the interstate at 73 MPH. in the electronic servo cruise along with the 468 spinning 1950 RPMs @ 73 MPH.
My two ton cruiser gets 20 MPG all day and night on the big road without the A/C operating. ( it drops 1-1/12 mpg) " Who cares its a fun toy".
So far with this combination I have driven my 70 Nomad over 38.000 miles.
I built this buggy for cruisin & long trips. I do not beat the heck out of it. I just have fun and drive it a lot.
NO I DO NOT RACE IT. Its fun to hop in it and drive from Pittsburgh, Pa. to Florida. As soon as the bridge is finished, I am picking up M. Merlo and we are going to drive to Cuba...............
Fuel milage in town, It sucks! Its like flushing a toilet.
I built my engine like a class 8 Cummins Diesel. A lot of cubic inches mild " Motor home cam "= low RPMs. All of this equals a TON of TORQUE. Torque is what moves things. As I get older, Its either " Race it or Drive it ". A very nice car, Gets very messy after a few years of racing. I does cost a lot to get that extra " TENTH " of a second.
