As far as the rule on rocker ratio. I think what the HRA’S need to do is measure the valve lift at the rocker. Measure the lift at the cam. Do the math if the ratio is correct or under they are legal. If it is over they are out. No matter what it says on the rocker.

I have a question?

What if the rockers are under spec?

We all know that there isn't a factory rocker arm that comes close to spec out of the box so what if your 1.6 ratio factory rockers come up 1.54 or 1.5 rockers are 1.46 etc?

Should you be bounced then also?

And I still do not know what, f any, tolerance NHRA will allow. Does anyody? Is a 1.65 RR in the tolerance zone if 1.60 is in the books? Are these Hemi rockers somehow marked as delivered (like a crane rocker for example) or is it up to the racer to determine the actual ratio? And was 1 or all 16 out of spec?
Are modern Hemi's more exact in the RR or are they like engines of yesterday, all over the board and you must sort through 100 to get the 16 you need?
And I would bet my last dollar Teuton had the correct cam lift as measured at the valve.
Unless I missed something Jeff is running the 360 LA Combo...

Right now other than a $4000 Set 0f Jessel contraption there are no aftermarket rockers. Supposedly one is from someone but my brain is too tired the think of it, I think a steel would be killer, the powdered metal is too brittle if it gets scored. A nice set of forged would do the trick.

But Jeff has a 360 , unless like I said I am mistaken and they changed it.

I got bounced once for an intake valve being to small by .001 No tollerance given there.

I thought there was a + or - .005" tolerance on valves unless the rule was changed, Paul.

Alex in my senario you would be fine with a 1.54 ratio when it calls for a 1.5. From what I understand from the earlier thread you can make up for the rocker with the cam lift. My guess is that is fine as there is probably no advantage to having a lesser ratio.

No......That is legal for stock. Anything goes in S/S.

Last time I looked the rule was + .001/ - .005. This rule came about due to the 426 Hemis having a problem with the valves clipping each other in S/S with the high lift cams. Dave Wren was bounced at Gainesville when I worked for NHRA in 1974 because of this. His valves were several thou undesized for clearance.

Don't mean to be nit-picky, but to avoid confusion, the Challenger DP 360's are actually considered to be the "Magnum" version. I believe someone said the aluminum heads are re-cast Edelbrock Magnum heads with the Mopar logo. There should be at least a small variety of rockers for them.

A "LA" 360 typically refers to the original style which came with rocker shafts.The family includes 273, 318, 340 and 360. Excluded are what they call the "poly" 318 in the early-mid '60's and the later 318 amd 360's in the '90s that became the Magnum family.

.....You did say you were tired!
