JD G AND 70 head

I have my own opinion on value but would like yours to compare... JD G Flathead value? Jd G Styled head value? JD 70 ALL FUEL head which will bolt on G block value? Thanks fellas
 
Is there any difference between a G and a 70 fuel other than the head and duplex carb? HP goes up from 36 to 45. If it is in the head, then it must be worth something.
 
I don't know which one is worth more, but a head without any cracks, usable guides and seats, no broken bolts, etc in good usable condition should be worth $500? Maybe I am way off?
 
I would think getting $500 for a cyclone head would be a bit much. I think $250 to $300 would be plenty. As for a G flat head it depends on which one you have. The F486R or unstyled head I would say around 5-$600 if you need one to restore an unstyled G. But I would not use this one for pulling. The better F49R has a better thicker casting and matches up to the styled block better. Not sure but I think this head was made for the later 53 G's when they were burning straight gas instead of distillates. I have one of these and think I can get $1000 for it. As for the 70 all fuel head I sold one of these 4 years ago for $1000 and wish I had it back. I think this would make the best power for pulling. One of these heads worked over should greatly increase HP/Torque numbers.
 
kendak, I didnt say they wern't still slated as an all fuel tractor. If you have seen many 53 G's then you have probably seen one with a flat head. They are easy to spot with a spacer between the carb and intake to make up for the shorter head. So whether the book says they did or didnt build a straight gas G you'd pay hell at trying to get one of these to run on distillates.
 
don't get your nnalert in a wad ...I've worked on more 2 cyl. than you've ever seen...I have a 47 "GM" ,50 "G" & a 53 "G"...ALL G's came from the factory as fuel tractors ...the factory only built 5 gas "G's" & these were recalled after field testing...the 70 was in production by then & there was no need for the gas "G"....alot of dealers used dealer installed gas or LP kits to change them over....all info that I have given you on production came straight from Mother DEERE...if you know so much call them & maybe you can change their production figures....BTW with so many aftermarket heads out there that flow way better than the "G" or 70 head your prices are way out of line...5 years ago maybe not now...I drove my first "G" in 1958 when did you start?...take care ...Kent
 
Have a 70 all fuel block and head which both are froze cracked.Would like to find a G someday.Head probably not fixable.Could you hardblock the head and be able to pull it.
 
Yup, worked with a truck driver that said he'd backed up more mile's than what I'd went ahead. He was pretty special to. I thought we were giving are opinions to Josh. Didn't know I had to deal with the correct police. If I want to know the difference between right and wrong I'll talk to my wife. Heck I'll introduce you to her.
 
My dad bought a new G in 53 I was in the 3rd grade. It was all fuel. We had no more than got it home than our neighbor got a new 60 gas, They plowed with them in the same field, both had new 3=14 plows. Dad came home sick, we had not got a 60 gas. The G used so much power fuel, I think it was 75% No 1 & 25% gasoline. it cost more to run it than the 60 on gas. He took it back to the dealer and they changed it to Gasoline. I think he said they put longer rods in it. Eventually got a 70 Diesel. a real tractor I was big enough to drive it, power steering. Vic
 
When you figure out what they are worth and if you want a new 70 all-fuel in the box let me know. DW
 
A friend of mine owns the NOS 70 All-Fuel head. Send me an email and I will give you his name and number. He talked like he would sell it. DW
 
Had somebody try to sell me an original rare all fuel 70. A quick look indicated a gasser block and head on the tractor.
Called the guy back a few days later. He just happened to have a rare all fuel 70 head and block from a 70 he had scrapped.
