Dan Rawls can do it if Wi is scared and wanted a non tractor bias person to run the test. As for Dan Rawlings the only Rawlings I am familuar with makes footballs and baseballs.

No cause a bone stock head cant flow half the cfm number wi boasts.you know his indy head came with flow numbers that indy provides and they are repeatable in wi and in tn. The deal wwas if wi cfm numbers were not stretched when i tested i would send him his head and 200. If his numbers were untruthful wi would have to pay me for my time testing to get his head back. To date no head from wi has been shipped to shop for testing.so one can only assume that numbers where inflated.

Anyone with basic porting knowledge knows that air does not like to turn corners. The AC head has 2 sharp corners. The air WILL become detached. No wet flow adapter needed, common sense prevails here. Eliminate the corners and it's possiable to meet the flow potential of the valve. Usually the allis head is at the end of it's flow potential by .400" lift. I'd bet by re-shapeing the port like in the picture and paying attention to valve aproach and seat angles there's a lot of potential power hideing.

yeah some where around 300 hp if the cfm numbers he post are realistic but he doesnt want to send the head down for someone else to verify or deny his claims.

i never said it was impossible . i said the same as i did above this time as well. sometimes a increase in dry flow can be a hinderence in wet flow.

Since the time of flow benches you get lump ports w ports and vane type ports and on a dry bench the increase in flow numbers from this can really show up. Wi said it can become detached makes me wonder if he has upgraded to wet flow technology without it the only realistic test is a tear down after engine has run to see where the carbon areas are in relation to the intake valve to know where fuel/air mixture has become unsuspended back to fuel and air .

A little bit of advise is to put off the camshaft purchase until you have settled upon the rest of your build for next year. There are some pretty smart cookies in the cam business but they are only as smart as the info you give them. Every bit as important as the correct grind  is timing, some good info has been posted about that but ask the grinder too.

to be honest i cant even stand to read post from my own subject cuz it always goes back to these two bickering on the same topic they bickered about dozen of times! All im asking for is help and advise on how to make my tractor more competitive for next year! im not looking to stick thousands of dollars into it, all i want is to be around 60 hp! 

Dr. Allis we do not pull with any organization, between work and life in general I rarely have the time to make the drive and compete with any of the clubs in our area. We may attend some of the closer to home brush-fair pulls a year and some fun pulls at tractor shows. The governor does control the speed at around 2200, i would like to speed things up but need to spend some money on a steel flywheel and beef up the bottom end first. Most of the time i try to get in a mph class under 5000 or if a open class was available for under 4500. We have a barney cam to install but have not done so yet, maybe this winter if i dont spend all my free time working on others projects. Figured the long runners would help with torque besides the factory manifold design looks hideous from a airflow standpoint. The individual pipes merge into a 3" collector, we put a 5" pipe over the outside just to keep people from being nosy.

2 is always better than one . lets you tune air/fuel for a pair of cylinders instead of four .  Have you noticed no 3 not running as lean with the pair as it does typicaly with a single?  kinda got a crhrysler cross ram look or chevy dz302
