Farmall 450 Weight

I was looking around the shed and it dawned on me I have enough parts to build a 450 with an M&W 326 engine and 18.4x38 Firestone Field & Roads. I have the steering shaft to build it without power steering and a Super M distributor drive to leave off the hydraulics. If I switch it to press steel can I get into 5500? I know we pulled one years ago in 5500 with all the weights removed and one fender removed, but it had 13.6 tires. I am thinking that with the extras left off and the PTO removed, and a lighter set of rims widened out then it might be light enough to have a little weight up front. What got me thinking about this is that the tractor would, at 10% over stock RPM, go 3.3 in first, 3.5 in 2nd with the TA, and 4.1 in 3rd with the TA. This would give me a lot of options based on the track conditions for a 3 mph class. With the right governor and other "mods" I can get 70 hp out of a 281 with stock cam so I should be able to get 80 horse out of a 326 pretty readily. I am wondering what people's thoughts are?
 
Should do it easily. Lots of places to
lose weight. But unless you already have a
1/2 stroke crank I would stroke it more
than that. Won't cost much more.
 
It is an M&W stroker crank so it is 1/2 stroke. Also it has the 4.25 bore so that is where the 326 cid comes from. It was in a 450 that had a cracked head on it years ago. Big smile on my face when I got the head off and measured up what I had bought.
 
Yes you did good. So you already have pistons. I would try to raise the compression as high ad 15 to 1 if possible. But I have found out the hard way. .030 clearance will work on a Chevy but not on your motor. I have .060 now. A old guy once told me, a natural aspirated engine will just push down 4 times as hard as it pushes up.
100 hp would be nice. 120 hp. Would be great. I'm talking engine hp. Above all have fun!
 
Your motor will have 75 hp and making 5500 lbs would be easy. 15.5 38 will be the tire you need because you don't have enough power to run 18.4 tires at 6000 lbs and up. you would be in first gear with TA back on power tracks.
