Billy very good point. Probably will take a few test and tune runs for jetting etc . Only difference is the guys will still have the 20K + motors when all is said and done but it would allow a test of the theory.

Dick, by restricting the intake AND the exhaust you take away the need for that 20K + motor. It may even become a hinderance as your big cam and heads are going to cause reversion issues at some point, something that you don't need with a restricted intake. I believe that cylinder pressure, gearing and an overall ability to tune the combo will be the major factor. I also believe that you would wind up with two totally different schools of thought in the long run, big, torque monster dump truck motors and smaller well tuned and higher winding modified type motors.

I understand Billy but the test cars would not prove too much towards the theory as you said they would still have the Cams, the heads, the parts.... We all are aware the small carb and exhaust would limit the performance so in some ways the testing would be of limited information.
As for monster truck motor remember the lb per cubic inch idea. No more 9 passenger wagons on steroids.
I am with Randy and many others it may never happen that an organization will decide to limit these specs BUT... just heard power boat racing has now developed a sealed or spec motor class. It has worked till now the guys are spending the money on trick hull for advantages.
Maybe if IHRA made any noise about it NHRA would do it to out do them.

Check into the APBA and let me know what you think then. They're hurting so badly for participants that they, on occasion, have to cancel races.
