I heard about the 12.08 timeslip and wondered a little myself. What were the 60' , 330' , & 1/8th mile times? The best time I've beat out of my Hemi Challenger has been 11.95 / 121 mph. That was with a 3850lb, 4spd car, making 667 hp at the crank. My heater, wipers, and all four 11" drum brakes, were on the car, and in working order.
I am not as surprised with the L88 vettes though, the pure stock rules were not written for them, but they may as well have been. Wayne Nelson and I, discussed at length, the advantages of L88/L89 and even LS6 Vettes in FAST racing. The advantages are obvious and too numerous to list. Unless someone offers a $50K purse for the winner of a FAST event, I'll just keep on doing the Don Quioxte routine with my fat elephant.

I didn't make it to eather race so I'm not sure what he accomplished in the 60/330/660. That car does stick like glue and it is pulling down the numbers. I guess running cam lobes that measure properlly at .050 are allowed. For some reason I thought the cams were to be stock. As good as the old LS-6 cams are I think their is something a little better that has come around in the last 40 years. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Jim, the operators of the PSMCDR have developed a "Certification" program to make sure that the cars meet their standards for "pure stock". They tear apart and inspect parts of the motor, and go over the car with a fine tooth comb. Jim Spetzmans 12.08 Super Bee, (and Jimmy Johnstone's Vette) are both Certified Stock. https://www.yenko.net/ubbthreads/imag...ns/worship.gif

I know what you mean Joel. The rules say they are only certified for the race of the certification. I'm sure Jim will certify this year but when the closed valve spring pressure requires HUGE valve pressures to keep the valve tran under control I'm miffed. I can see that I brought a knife to a gun fight. https://www.yenko.net/ubbthreads/imag...lins/blush.gif https://www.yenko.net/ubbthreads/imag...mlins/hmmm.gif

My oversight on where this was going! (camshaft rules)

Just went and re-read the rules posted over at the PSMCDR site...not sure if this is a new addition, but here's what it says under camshaft... https://www.yenko.net/ubbthreads/imag...ins/tongue.gif

"In order to pass Certification, we will also be requiring that camshafts have correct intake and exhaust duration. We will be checking your camshaft's duration at .050" lift. This is to prevent the engines from being over-cammed, but more importantly, from being under-cammed! If you have a question about you cam's duration, please call ASAP!"

The way I read it and how I think Dan looks at it is you can run anything beyond .050. So on a LS-6 cam if the the cam runs 242 degrees at .050 you can make it lift as fast as possible after that. Let the lobe slam the valve down as quickly as possible at the back side of .050 measuremant but to end up with 242. Again what ever is under the curve is above the .050 mark is legal.

Use your imagination if you want. You could run a launcher lobe just like the circle track guys that have lift rules. After the cam runs a certain RPM the lifter jumps the lobe to be caught on the back side of the ramp. You could run a cam .035 bigger than what is leagel and also run a duration that could never be measured by standard rules. All you would need to run is spring pressure and piston clearance that would allow clearance https://www.yenko.net/ubbthreads/imag...emlins/eek.gif.

Pure Stockers at 12.08 and the FAST guys can't even get them to go that fast! This may be the beginning of the end to anything close to the real deal! I'm waiting for even some of the MOPAR guys to scream foul but I may be holding my breath for a long time. https://www.yenko.net/ubbthreads/images/graemlins/no.gif

I'm sure that you're talking about the R4 Six Pack Bee that I raced in F.A.S.T. up at Musclepalooza. Let me say, that, the car that I raced is actually a lot closer to Pure Stock than F.A.S.T. I built that car before F.A.S.T. and the Pure Stock Events were around, so I built it my way. It's a .030 over, measured 11.9 to 1, 440 with a flat top piston .010 out of the hole, it's got a small solid cam from Straightline, roller rockers, the heads are stock with just gasket matching, and the intake is gasket matched. It has absolutely nothing trick. Up in New York, with non treated tires https://www.yenko.net/ubbthreads/imag...mlins/grin.gif , it ran 13.0's @ 108. I brought it back and ran it here with the dumps opened up and on a set of worn out BFG Drag Radials on a cold track, it ran high 12.20's @ 112.9, so I know that it's time for some better mufflers than the Turbo's that are on it. My times are fairly comparable to the 12.0 Bee, although mine won't pass Certification, so I'm sure that if I had built my engine specifically for Pure Stock and I did some creative interpritation of the rules, it would run similar numbers. https://www.yenko.net/ubbthreads/imag...lins/beers.gif
