Thanks guys,

I think the pumpkin weighs about 80 lb, not so bad to pickup if you have to.

The difference in 5.14 and 4.10 gears is 20%
So drive same speed with 20% lower RPM or same RPM as before and go 20% faster.
Another way to look at it is a 4.10 gear change (with a direct drive transmission) is similar to having a 0.80 overdrive ratio with 5.14 gears. Same final ratio or speed in either case.
Hope that helps.

Today I stopped at a real neat vintage wiring place (close by!) and ordered an original type wiring harness. Only had time for a real quick, incomplete, tour of the place.... Must admit I am thoroughly impressed by the quality and attention to detail, to say nothing of the cool old machines, incredible inventory of components and finished products. On top of all that the owner is a wealth of knowledge and enjoyable to talk to.
Stay tuned for more wiring harness info in a month or two smile
