The John Deere alternator is a work horse. It’s great for street hot rods with lots of radio and power everything, will charge great at an idle. I can’t see people of saying they were burning the Toyota ones up at the track?? The Toyota if they have brackets available is a pretty good choice.

John Deere 14.04 lbs, Body Dia. 5.4”
Toyota 9.88 lbs, Body Dia. 4.5”
CS130 11.4 lbs, 5.25” (130 centimeters, it’s where it got its name)
Baby Denso 6.39 lbs, 3.75” body (little heavier in 80a mode)

The John Deere alt would be great for cruising a hot rod with many accessories. CS130 is a pretty good choice for firing your car down the strip or even street driving (sometimes have issues at idle if you try to step them up too much), lighter and economical. Baby Denso would be great for the track, I really wouldn’t recommend it for street stip. A stock one makes 35-40 amps, I have special hand windings made to make them 80 amps and would be great for the track, hand winding is expensive and it won’t have the power at the idle or durability of the others. All can be made 1 wire, or 16 volt pretty easy.
