That one has a 134 engine and with the ford truck
trans and rear would probably do 40 miles an hour
on the road. I don't know if I'd swap it for a
bigger engine. My concerns would be the brakes and
steering at that speed.
My G10 has a 192 engine in it and can hit some
scary speeds with plenty of pedal left. I don't
drive it that fast, guess I'm too old for that.
If you think about the asking price of 750, which
he may or may not get, it's just about the price
you'd pay for a good running engine to transplant
into a tractor. My G10 "tractor" has the truck
tranny granny gear, full hydraulics,3pt hitch,and
pto so it's a little more functional then most.
I have seen the earlier model G (8n tin)done up
with a flathead V8 and all chromed out and it
looked real cool.
Some don't like them but I do.
