How about an Olds engine masters style competition?
Did any of the original dyno queens ever make it into a car(s), or do they get parted out or shoved under a workbench? I don't recall ever seeing anything resembling "Engine Masters Olds Small Block Sets "X" Record". Theoretically, they put even the most advanced super stock engine to shame, but they get raced.

The engine masters was designed to highlight an engine builders ability to make the most HP/TQ in this case pump gas street engines.
Like Mark said stock and supper stock engines operate in a very specific power band range.
The point of an all Oldsmobile Engine masters challenge would be to give a chance for builders to test there skills against other builders.
The engine masters engines are built on the edge and by the time the competition is over they have had many dyno pulls both factors effecting end use.

How many ex EM Olds engines are there? Half a dozen? Ten? I seem to remember one being sold here or ROP a number of years ago but these things aren’t exactly as plentiful as Predators at Harbor Freight. (no knock insinuated against HF clientele if taken wrong, I reference small engines)
…

I'm most curious about the one with the Wise heads, Glen or Gary Somebody (?).
Given the scoring platform with highest overall average tq and hp, they should be able to live in a car or at least provide "down track results" that are mentioned here so often.

I agree it would be cool to see these engines perform at the track.
Diesel based small block 403”
Ports were tall but not big enough, could not port much because water was too close''
So, where did it go? What happened to the 307, Dale?
Also, were they Wise heads or billet Battens? Everything I've read in the past 6 years said Wise.

He’s building a smaller inch gas block with one of my halos and block fill, but still going to use the Wise heads.
these flowed a bit over 400 max and were not maxed out because they were used on a 400” engine that also needed to make a lot of low end TQ. The port cross section was fairly small
I have a set of battens here that are maxed out and go around 340.
ya it finally threw a rod. Hundreds of pulls on that bottom end over the years. Those heads as they are, are best suited for 365 to 370” . They were small for the RPM range of the competition as the peak hp came in about 6500
this pull was to 7900

Hmmm some dyno data that makes some sense, whats the VE?
a high winding stocker small block may have quite a bit higher VE as it will come in near peak HP.. the high rpm will have a greater influence on VE .
a much lower RPM big block stocker may see it’s peak VE at or closer to peak TQ.
im not sure anyone is chasing a VE number. It’s easier for a very narrow rpm band engine to achieve a high VE because you are not concerned about anything outside that range.. you can put all your effort’s into a specific range
its a real challenge to get the VE ideal over say a 4,000 rpm spread, especially if the range starts low like 2500 or 3000
that’s like asking how high is up? 😁

Thats a great question, I don't have any of the tests from that engine since I've moved, but I bet its around 100. When I have it on my dyno in the future I will post it. I will say for the record: My 455 Buick is the low HP combination, not a stage 1. Actual 10.67 compression, .398 lift cam, 2.000 intake valve, been 10.69 in F/SA @ 3650, 1.38 60. The 70 Stage 1 combination has 13.5 compression and a .490 lift cam utilizing another 30 CFM of air flow.

I know one thing that they never did when I was there… they never adjusted the correction factor throughout the day. The engines that ran late in the day usually got screwed out of some score. The outside air feed was feed through the roof of the building. As the day got hotter , the air supply got worse.
I’ve got a cd disc somewhere that they gave each competitor of the pulls. I’ve never even looked at .. I’ll see what’s on there

there was a big kerfuffle when it was discovered the correction factors were screwed up. From what I understand the settings can be manual or self correcting on the correction factor.
i seen plenty of questionable things happen while there.
i see in your pic the ex exits do not have a sealed system at the exits and your turbine doesn’t have a sealed supply either?
or are they just not hooked up?

back then they were using DTS Powermark dynos and WynDyn data acquisition.

1. In your opinion what are the conditions (weather) for a STP correction on SF dyno?
2. What conditions make for a zero DA situation at the drag strip?
3. What is the known barometer @ sea level?
4. Do you believe the Moroso power speed calculator is fairly accurate?
5. Do you believe the Moroso power speed calculator shows crank shaft HP in observed conditions?
6. Have EVER seen a dyno operator say any thing other than this is a conservative dyno?
I ask you these questions because I want to make sure we agree on the above questions before we get into any dyno testing talk.
How is it that you’re now a Dyno expert when not long ago you were a Dyno dumbass? Just curious.

REALLY, the only dyno I trust comes after a full-pull, you get a print-out with time and MPH over distance for your weight. THEN google Stan Weiss OLD Hp calculato and makes you CRY as you get a true representation on what Hp your making on that day, in those condition and with that set-up. Yet like Vortec/Mark said, that's a conservative dyno..
Every dyno is said to be conservative, every flow bench is stingy.LOL
