Trying to make my WC puller come to life

I have a allis chalmers wc puller. It has had work done to it but needs more power. What should i do to it in order to make it more competitive. different motor?
 
I pull from 3500 up to 4500
it needs more power. Ive been told to find a gleaner motor to go in it but have had no luck at all on that
 
Put a WD45 engine in it then do mods to it. A WD45 engine is a straight bolt in and will up the HP to around 45HP but not add much weight to it
 
The little things like maybe mill the head a tad bit for more compression ad if you really want to ad some semi cheap HP polish the intake and exhaust area of the head
 
Well a stock WC is right at 30HP so going with a WD45 will bring that up to around 45HP just stock. Now if still want more and have the $$ to play with you could take that tWD45 engine and do an over bore sleeve set, mill the head and maybe do some carb work. If you really want to go hog wild find some one who can port and polish the head for you and that would open it up a good bit more but that also cost your some big $$. A simple polish job one can do with a simple demail type tool and some time
 
if ur running 28'' ruber then a 45 motor is more than enough in relativly stock class, if u want to run larger tires or higher gears the your talking about building a pulling motor
 
Well it has had some work done to the motor. Ive had some head work done to it, msd ignition. and other things but just not enough power at all. Would a wd45 help out much?
 
Well as I said the WC is a 30hp tractor and the WD45 a 45HP tractor stock so unless your WC is pushing 45HP yes a WD45 engine would help a lot
 
Unless it is warped milling a WC/WD/WD45 head will do nothing because the combustion chamber is not in the head on these engines. You can easily upgrade your WC engine to WD45 specs. by using the half inch longer stroke crankshaft from the 45,manifold and carburator. A common cheap trick is to use the WC OR WD flat top pistons with the WD/45 crankshaft to bump up the compression or using 170/175 crater pistons. If you are changing pistons it make sense to go the over-bored 4.125" inch sleeves and pistons. By installing the 45 crank together with the larger bore, your WC goes from 201 cid to 240 cid. Of course you also want to use a governor spring from a D-17, 170, or 175 to get more RPMs from your engine. Good Luck! Kip
 
these are flat heads,milling i"snt gonna help,find a e-gleaner engine,if u can"t,thats ok,bore the block to 4.125,use WD pistons,re-grind yor cam to 175 specs,do a good valve job,send the carb to Motec engineering in Indiana,assembly it very carefully,get a part-time job to pay for all this,my wc dynoed about 65 ponies,oh ya,get a 175 gas gov spring,good for 2000rpm"s,your gonna think u died and went to heaven-no BS.
 
Sorry your wrong. Both the WC WD and WD45 use valve in head engines. This is the A/C forum not the Ford N series forum which are flat head engines. O know the WC/WD/WD45 well since I have or have had them all and THEY ARE NOT FLAT HEAD ENGINES
 
What they mean by 'flat head' is that the bottom of the head is flat, there is no combustion chamber at all. The combustion chamber all in the piston and sleeve. So if you were to mill the head, it would not change the compression at all.
You are right in that it is not a valve-in-block engine.
 
Ya I knew it was a flat bottom head but he said it was a flat head as in valve in block engine which it is not and yes depending on how if is milled compression would not come up.

A good runing WD 45 should be all the engine you will need in those classes. Add a set of 38" tires and wheels and you should full pull all of the time. Unless you have excess cash, I wouldn't bother with engine mods. With the 45 bore and stroke you will be hard to beat.
 
go too the tractor pullin forum they are alot more helpful with this they have been there an done it.but adding a 45 crank too wd or wc flat top pistons will increase compression an cubic in. it isnt necessary to purchase a gleaner E engine or d 17 engine or even a 45 for that matter the 45 crank will fit in the bottom of a wc or wd block
