And question : weren't ALL the really high performance cars back then designed for open headers and not intended for the general public too? I thought the LS6 Chevelle and the RAIV Pontiac cars were like that, with really aggressive cams, but those cars seem to run well in stock form, where the 70 4-speed W-30 didn't seem to run that well. Im just asking because I always see these other cars like the Pontiacs, Chevys, and Mopars winning those Pure Stock events, and it seems like those cars had really radical cams too, but they seem to do well.

YOU"RE KILLIN' ME! I understand the argument though. It may be that Chevy & Dodge were much better able; or willing, to match the components. Most of these cars did come with rad cams like you said.

I've never seen drag results for the 4spds at these events in any publication. Are they represented at all? If not it could be that the owners don't want to race their car. They're not aware of such events. There may not be that many left so they get poor representation. Or; as with my car, the original engine is long gone making it unavailable for pure stock/musclecar drags. Would mine qualify with a service motor?

I ran mine full out a few years ago only to discover that when I put the intake on I rolled the gasket in back and was losing vacuum like crazy. Here's a vid http://www.youtube.com/watch?v=5y_OKnABGJ0

The distance in the vid is (a crude) 1/4 mile. It's up a grade and I had to slow down for the on coming car. Using the YouTube clock it puts the time at about (a crude) 14 seconds. Not really a definitive anything. But cool.

Well I'm pulling for the 442's! I know the Pure Stocks are not the end-all of all of everything, I'm just wondering why the 70 W-30 doesn't seem to do any better. I want to go to one of these events but Michigan is too far for me. I found the results from 2007 and its in an .xls format (Microsoft Excel). I hope you guys can open this up.

I would love to see a 66 W-30 and a 70 W-30 at the top of the list!!

Off thread? You started this, Mr. "Don't want to stir the pot"!
Oversimplified, but:
Think of an engine as a big breathing machine. Air in and air out. Headers get the air out much better than stock manifolds of any kind. The 328 cam gets the air through the engine much better (more lift, more duration, more air), so without headers, the engine is choked down at the the exhaust manifolds.
In fact, on the same "W30 Conversion" page I earlier referenced it said all the stats on the engine was "with headers". So just imagine how incrementally less the figures are with stock exhaust.
you had said that they were intended from the factory to have headers but stock manifolds were added when sold to the general public? So if it was intended to have headers would one that now does have headers be considered "stock" and if not why?

I'm having a very hard time understanding your point of view. By better do mean nothing short of "top of the list" is satisfactory?
I didn't spend a lot of time on that list but I saw only one '66 W30 @ 13.66 and only 1 '70 W30 (auto or stick?) @ 12.81. First, there is only *1* '70 W30 and we don't even know if there is a 328 cam there. And you have a problem the times even? How far from the top is 12.81? And how many are below it?
First they have to show up "do any better".
Second, Olds never did make or try to make *the* quickest/fastest "factory stock" car.
12.81? Pretty darn good!

Okay, first of all, when you say "stock", in what context are you referring to? Out of context, it really doesn't mean anything. Here's what I mean:

If we're talking about "stock" for NHRA, then headers are stock. This was the whole direction of why the engines were designed to use headers for maximum performance.

If we're talking about "stock" for OCA in regards to judging, stock is the way they came from the factory. No headers. Simple. They did not come from the factory with headers.

Headers were "required for maximum performance". They didn't need to be added and often weren't. It isn't like they came without seats and then seats needed to be added to even drive it!
Racing tires were needed for maximum (quarter mile) performance too, but....well you get my point.

Kurt - Did you determine the '70 to be a W based on the hp? I didn't see a designation for any W-30's on the list. Do you know this car? I seen it/him several years ago at Quaker Dragway in Salem and it is W-30 auto. That being said. 12.8!? As much as I want see a '70 W pulling those numbers I gotta wonder about the tech inspections? That just seems awful quick for an auto/3.91 geared car (w/what should be the smaller cam). He must be a helluva driver. (and he wasn't when I seen him, I have it on tape) So unless the 4 speed cars are truly 'dogs' in the performance sense, I wonder if the original owner of my car was right when he said that he was turning 12's also.

Yes, just by the hp. No, I don't know him or the car. Yes, that *is* a little quick for a 3.91 auto. Can't blame the tech, there is only so much they can do, and you better believe that there is wholesale mods (yes cheating) going on there.
FWIW, I went to the first "Musclecar Showdown" (I think it was called) at Quaker City back in 1987 or so. Still have the t-shirt..........

A lot of those cars seem "a little quick". Timing, shift points and tire pressure must make a whoooole lot of difference.

I was at the same showdown. I think I saw you.

I Googled Darrel and found out that he races a '70 W-30 at the F.A.S.T. events. This might explain the e.t.'s referenced earlier. I didn't check for other car/driver combos but they're probably scattered amongst the contestants as well.

Nothing wrong with F.A.S.T. In fact, it just amazes me what these guys can do with these cars and keep them looking so ordinary. I don't know that I would sacrifice a legitimate W, Shelby, Hemi-car etc for this purpose though.

Darrell D. has a few cars. Don't automatically assume that it's always the same car that's being referenced.

Kinda hard not too when the car listed for the Pure Stock Drags runs the same time as the car that was ran at the F.A.S.T. drags.
