BEST PULLING TRACTOR FOR THE BUCK

Now I've heard it all. .300 shorter valves and springs so stiff it takes an extra 5hp to operate the valve train. You got the part # for those valves?

yeap standard sbc  you want manley or ferra . the valves pretty well fix the factory rocker arm geometry issues . not to mention .300 less mass to make up a extra 10 hp for the 5 as you say lost .

No it won't, it hasn't yet. If anything deliberately making an off topic post (Smack Talk) in a specific section of a forum aimed at pulling to do nothing more than stir the pot should get you kicked off the forum.  You're a waste of bandwidth.  [/QUOTEif i was you and had no mechanical input to the forum I wouldnt push it much. Are you trying to play moderator now Spankey?  Go cry a river somewhere else.

nope just take him at his word

Shorten them .300 and you can't install the spring. If Installed spring height to 1.8 you'd be cutting through the top of the head. You're Comp spring 944 is 1.570 diameter with a spring rate of 753 pounds per inch. At 1.8 installed height it's at 302 pounds on the seat, after .600 of lift it's at 754 pounds. But you've got even shorter valves. It don't fit. The 920 spring will work out, barely. Why use such large diameter springs anyway? They add weight to the spring and rob power.

you dont follow well if you read the heavier valve sprin topic you will find that i only use and only say to use the outer spring but i do see you read it to find the pressures that it has in my post using it as a double spring like sold. Your lack of  knowledge is showing the sbc valves are the length you posted and that is .300 shorter than the factory allis valves that are the same length as a bbc valve if i remember correctly offcoarse you wouldnt know that cause you havent ever been into a 226 engine to even know that the exhaust spring seats down into a macined recess thats not machined around the intake guides

Bbc valves are 5.422 long. That's more than .300 more than 4.910.

You really don't follow yourself well and have no basic math skills. Better go edit your posts as no where do uou say to remove the inner spring. Why buy a $350 set of springs anyway?

Edited by Rod B - 10 Mar 2013 at 9:38pm

why buy the springs they are readily availlable in shop cause i use them on so many race engines we do. sbc valve .100 long if you run the part number ps they are 36.00 a piece that really doent say much for your knowledge i tell you it 300 shorter than factory and you cant figure out without me telling you its a sbc. 100 longer than stock

Coming from the guy who thinks a combine engine is junk. I love mine, won me plenty of trophies...

5.161 is allis valve length. .300 shorter would be 4.861. Sbc valves are 4.910 and 5.025. That's not .300 unless useing pankey math. Buy yourself a better tape measure.

mlpankey wrote: Nope allis valves are bbc length at least the ones i have pulled from old heads. Have you pricex allis valve springs

Again the allis valve is 5.161 long. Bbc is 5.350 and 5.422. And useing used valve springs is a no-ny. Springs take a set and useing used ones in a different motion can cause failure. Skimping on critical parts by useing used valve springs and soft connecting rods is a sure way to end up following internet forums and not leading them. Your lack of knowledge is showing more and more.

True about the D17, has to be '59 or older for most classes. Also a lot of pulls won't allow you to below shipping weight.

WC's have many pros and a few cons...cheap purchase price is great. With hundreds of thousands built but being not much more than a horse with tires (no hydraulics, has hand brakes, no live pto) they have little popularity with working hobby farmers so they're cheap. Another pro is as far as engines go you can swap in a d17 WD45 or Gleaner E engine for quick power or build off the solid platform of a 201. They can be made super light....3500# is easy but 3000# can happen. I pull 3500-4500 with my 45 WC and for bone stock other than a dry aircleaner setup, a new governor. spring because my old one stretched and open exhaust its fairly cometitive. Biggest downfall is gearing. They're geared high but an RC rear can fix that

Just to be clear , the local association wants , stock tractors , dont know how srict they are
