JD 50 motor work

[team flat black]

I am looking to do a little pulling with a john deere 50, can anyone tell me where to start as far as what mods I could do with the motor, and what i could expect to make for hp?

 

[BushogPapa]

Oh, I guess you would top-out at about 120 HP, if you want to go that far...(no kidding)..!!

How deep are your pockets and how much HP do you want to make?
A good running 50 can spin out in 1st gear in the 5500 & 6500b class no problem.
First three things to make distance down the track before adding HP is. Traction, traction and traction.

I do believe your crazy.....120hp is VERY hard out of an A..and fairly hard out of a G....no way for a 50....

hey i"ve been writing down a few ideas for my 50.(the Peashooter) my email is open if you wanna swap ideas.

 

[730lp]

crazy, I'm with you on this one. Took me 900 cubes to get 120 hp from a G. Now 900 cubes from a Moline, that another story.

dont forget balance!

I think you would be right up there if you did the head right at 500CI

no crap....530 in an A isn't but 85..but an M IH at 530..theres a 125+.....a 2 cyl is in-efficient when it comes to hp. neways...didn't want the 50 guy to be pumped up with falsehoods..thats all.

 

[Little Big B]

you must not be doing something right then because an A around here with just 415CI is right at 70hp.... 85hp at 530CI seems a little low dont ya think?

The next time you pull against JDBPuller, don't mention HP..OK..?
Just to "Hold it Back", he uses 4th and 5th Gear...!

Ron..

 

[730lp]

and he pulls one plug wire off to "Hold it Back"....

 

[BushogPapa]

Ya suppose...???

I gotta try that...

What you can do is limited to your wallet, time and imagination. Here's some ideas and relative costs/HP for you to consider

(205 cubes) 40-45HP+ - Just overbore it, new pistons/rods and bump the compression - About $1000 plus boring

(280 cubes) 50-55HP - Overbore, new psitons, stroker crank, cam, rods -- About $2200 + plus boring & head/carb

(310 cubes) 55-65HP - Powerblock bored to 5.125" w/Stroke (same cost as stock block but you have the additional cost of the PB in there) + head/carb

(400-450 cubes) 80-100HP - 5.75"-6.125" block, crank, cam - About $5500 + head/carb

(520 cubes) 120HP would be a fun number, but would take considerably more work & money. (moving cam, big crank (thinking 8.5"), 1600-1700 RPM's, 6.25" block, you get the picture).

I don't know the actual HP, I've ripped all the PTO stuff out of there, but mine is in the 4th group, and I always leave both plug wires on
