Mack, Dr.Allis

Rules down here are letting any agriculture motor into a 1959 tractor as long as its naturally aspirated and doesnt turn over 3000 rpms and speed limited to 12 mile an hour . The oliver boys with the 320 cross flow heads are happy. How hard is it to fit a 426 in the wd or wc frame . How hard is it to change to a gas engine also .  I would like to make some cry foul.

A 301 diesel  may do the trick , you can get a bunch o power outs that little motor

yeah i have seen the 301 thats why i wanted to go bigger . I am not for sure the 301 has the cross flow head like the 426 does . Thats been the 320 wakeshaus advantage and  the logic behind the rule . They also pull this class all the way up to 6500 lbs . On the few the proud the orange there is a 5/8 stroker crank and pistons to make 598 ci out of the 426.

301 is a crossflow, but has shared exhaust ports. 

cant join them its got to be different or its not me whats the fun in being the same

 I guess you should be able to drill/thread/machine the injector holes to accept a small spark plug similar to some modern (Ford Triton) engines. Cut the pistons a little to drop the 16 to 1 compression down a bit and regrind the camshaft to gasoline specs and rig up a belt driven governor to a carb that is attached to the intake manifold turned upside down.........yeah....should run good, but I'll bet 426 cubes ain't enough !!!!! Them Ollies are as big as 500 cubes in some towns I hear !!.

I left you a message on another sight.

think a little harder if it's legal to use an engine from a gleaner combine.  Pretty nice heads.  Individual cylinders.  Cross bolted mains and a nice light engine to start with, aluminum cylinders and heads, cast crankcase.

Does that mean you could use the duetz engines or any agco engine presently used or the big N7 motor. What about the V8 cummins out of a 440. Should be able to use the sugar babe motor since they had a couple for ag.

I sure wouldn't spend much time considering such a rule, it will eventually become a back to OEM type block and head.  I'll stick with an engine more "correct" so when things change or one wants to pull somewhere else, sell it or what have you.

I think our combine had something like an f8l413 engine, I don't rember exactly.  It burned and we were glad it was gone.  It was an R62, twin turbo.  Older ones were natural aspirated and around 230 hp.  Thr big Duitz was a torque monster it would just about tear the engine out of the mounts in high load situations, mud, hills, etc.  The Cummins was a dog compared to a duitz.  Our new John Deeres don't have the torque backup the big kraut had.

Would allis ag crawler engines count, if so thats a big list including Detroits but I have yet to see one pull that was anything but loud.

I saw a Ford 500hp. Tank engine in a W9 International pull once it did real good.E.J .Potter of Ithaca Mi. used to pull Double Ugly with two Allison aircraft engines it was fun to watch him pull! This idea of putting big blocks in WC's or WD's sounds like an accident waiting to happen!

sheetmetal makes one appear to be what sometimes it is not.

Here's a 301 in a 45.  Has a oliver wide front.
