Dave and Spartan - if you are happy, then I am happy
However, for comparison:
Competitive make (not Chevrolet) 1/2 ton pickup 6.5 litre (it is U.S. but this way I don't advertise the make) engine w/truck 4-speed and two 625 CFM Carters with solid linkage on Offenhauser intake manifold, approximately 450 HP. Engine was built with high performance factory street cam, and high performance factory street cylinder heads. Running points and condenser.
Performance: no hesitation from idle to W.O.T. in first, second, or third gear. No hesitation in four from 1000 RPM to W.O.T. (this is flooring the throttle).
Economy: pulling 16 foot trailer with JD 425 and JD 335 lawn & garden tractors at 55 MPH in rolling hills - 17 MPG
Economy: truck with no trailer 70 MPH interstate cruising - 22 MPG
Reliability - this is the 19th year they have been on the truck, and have not been apart since installation.
I will readily admit to tweaking the calibrations slightly.
You may make your own comparisons.
Jon.
