Hemi Head Ruling

[SSDA Hemi]

Two scoop Lido! That's some funny stuff right there!!

BUT- this story only reinforces David's allegations! If he was in a glass house he would've finished the race with the tall scoop and the following week an addendum to the rules added allowing tall scoops,

I'm all for tickling the rule right to the legal limit. But this 1/2 Hemi head stuff just doesn't do it for me

RPM is the killer here....i may be wrong but if the intake rule had been enforced then the need for such crazy head flow would ouf been lesser..
wonder what the cars would be running if we went back to real crossrams...and would it affect the rpms that seem to be the norm now??? david???charlie???....need a rule like farm boy pullin tractors have???rpm telltale ...limit to 8800

That would depend on how short you could get the runners in relation to the plenum and if there would be any deficiencies in the air/fuel mix due to the cross ram configuration. The rpm their running probably has much more to do with the valvetrain innovation than anything else I think. Between Charlie and David, they have gotten the valvetrain much better in recent years.



On another note, is Super Stock another world where your only going fast if your cheating(knowingly breaking/stretching rules)?

The biggest problem with this rule right now is the way it is written. It leaves way too much room for interpretation! With the creativity and $ in AH right now, it may start initially as a 1 inch manifold spacer, but how long until the spacer is 3 inches with the inner had studs being utilized and it actually serves as the rocker stand! The only thing stopping it is the combustion chamber and its just a matter of time before it becomes a section of that. That will make cc'ing a Hemi head in tear down fun!

I remember seeing this done by Richard Maskin with his pro stock Rambler (hornet) before the 500 inch rule came into play. It transformed the port from useless to a player. This was brilliant ( i thought ) at that time

AH Hemi heads don't need this technology to go fast.

I remember a sign in the trailer of a fast race hemi car it said.

"There are only 2 kinds of racers!
Cheaters and Losers"

Bringing back the crossram might solve the controversies of SS/AH.
What do you think?

[Jeff Teuton]

Change is Coming. Some will like it, some won't, but it will be different.. 2 or 3 weeks maybe.

Our old crossram motors would peak around 7900 rpm, shift around 8300, and run around 8900 through the stripe. I'm sure they could've been made better, but I doubt very seriously that configuration would go 10000 rpm.
