great post!! and...it sounds like it was a good time, despite all the BS up to that point. i am confused about one thing though....you were mentioning the odd cam specs of the one entry... ("like I said in other post cam was very unusual, I'll be checking out exact specs on that on Monday from Comp. I've never even read a magazine article anywhere with specs like that cam has, such low duration (238 intake) and yet alot of lobe lift (.420ish)and a wide LSA") ......but i was under the impression the cam had to be an "off the shelf" item. sooo.....which page of the Comp catalog is that cam on??

very informative thread. it looks like the folks at R&S had most everyone covered by nearly 100 Horsepower. do they do their own head porting? glad you were treated so well and had no fried wires.

I recently sent some email to Eric asking about his 99 hemis. He was very informative and answered all my mails.

Yeah..... you're going to get a call about that one on Monday. I'd like you to have a little chat with Chris May's about it. But no it's not in the "current" Comp Cams catalog.
DRAM they did'nt port their own heads, he told me who did them but it was not anyone I had ever heard of, it was just some small shop near them in MN. I got to see them during tear down, and we have some pics on the shops dig camera. They were nicely done, but nothing exotic. We were not allowed epoxy or welding etc. There was not any 1 component that made their power so much higher than everyone else, it was just a combo of everything.
They had 440 inches, as did most of us, but not all (Stark & Maurer built less)
They had 15:1, where most of us had alot less compression, We were about 12.1, Shelton 11.9, Stark 13.3. We all kind of stayed more in tune with "street motor" theme as far as compression.I know we could have got away with more in CO, but these motors now have to spend the rest of their life on the East coast at 1000-2000 feet DA, and we all took that into account. I really did'nt want to build a 15:1 motor that needs to run on $15 a gallon gas, if it's not in high elevation.
Their cam was "questionable" as far as legality of being an off the shelf grind
They had 1000 HP carb, one of the 2 biggest in the contest.
They had a Super Victor intake which obviously is a good piece.
The heads had oversize valves which we did'nt do because it was supposed to count against us cost wise, but that rule got changed the Monday night of the contest. I had stayed with the 3/8" MP 2.02/1.60 3/8 valves, used a cheap Comp roller spring, and moly retainers because of cost, they had oversizd 11/32's with Ti retainers etc. And did not get penalized cost wise due to the last minute rule change.  So they had good heads...
They used 1 7/8 TTI headers, which would be the biggest ones used in the contest.
They had ~35 dyno pulls on it in MN, by far more tuning time than anyone else. We had 6 pulls in PA having issues getting on the dyno, and then having an adjuster back off and having to drive back to shop for backup rocker, Stark had about 1 pull as their dyno servo or something was messed up, INDY busted their intake rocker stud mounts due to aggressive porting, and had limited pulls due to fact they had to replace the block and make a stud girdle, and Shelton had bad valve seats and vacuum leaks and got limited tuning done.
They had 1 of only 2 roller cams
They had the highest overall MSRP cost even with the lack of cyl head parts included by a wide margin.
It all added up to the biggest power #'s, it was'nt one specific thing, just like in any engine it was the overall combo.
They pushed the limits of rules/cost/parts/and fuel farther than anybody and got away with it and won. They were by FAR and away the most prepared, and generally the best prepared is going to win. The lack of build time I think for them was helped out by the fact they were the only ones to subcontract out their head work. Everyone else did theirs in house, and with 30-50 hours+ eaten up right there.... that hurts. That would be my BIGGEST complaint about the whole contest, other than the constantly changing rules, it was just the overall lack of time from when we finally got our parts to when the motor had to be there. This was'nt like Enginemasters where you have half a year to work on stuff, this was a thrash.....
