It's a 482" Sideoiler in a service block, 10.5 to 1 CR, Keith Craft Stage II heads, solid roller cam, specs are 255/262 at .050 with .383 lobe lift and a 112 lobe separation. It's installed at 4 degrees advanced at 108. This cam gives .674 lift on both the intake and the exhaust before lash with 1.76 Harland Sharp rockers. MSD ignition with 6AL box, Edelbrock Performer RPM, port matched to heads. Quick Fuel 950 carb, aluminum RAM flywheel, Canton oil pan with windage tray, high volume oil pump. I don't know the size of the headers, they're Cobra replica headers and sidepipes, just use whatever headers would be used on a dyno test so I can compare apples to apples, I know the Cobra pipes are power killers. Am I missing any other specs you would need? Thanks.

I guessed 2"x31" headers which gave

Torq 583 at 4600

powr 599 at 5900



Using 2 advance instead of 4 gave near the same at

Torq 579 at 4600

Powr 604 at 5900



Since that Cobra is quite a bit lighter than a 767 (my favorite type of air travel, one one sardine seat per row) the 2 advance might work better if the exhaust is loose enough to let the 604hp out.



1-7/8 headers gave up about 10hp, and 2-1/8 gained about 3 more.

Edit, all these are gross (open exhaust, 60F dry 29.92 to the carb, etc) so the pipes don't enter in yet.

With a name like "Gonkulator," what formula or software package do you use, or is it a mathmatical equasion you figured out for your own purposes? Do your h.p. and torque #'s reflect flywheel or drive wheels? I ask because in the several results I've seen here on the forum, results seem to be very reasonable, concidering how the "factory ratings" were restricted by insurance companies, and federal regulations, back in the day, and for today for that matter! I would be curious as to a comparison with say, "Deaktop Dyno" or something of that sort! Have you ever tried a comparison- just asking! Dean

it got named the "Gonkulator" here on the forum, and the "WerbyFord" part dates back to 1968. One of the other guys (either DesktopDyno or Engine Analyzer) is ironically out of Ann Arbor too, but the Gonk started there totally independently, just a hobby during the long winters we used to have before Global Warming. It's a whole lot of formulas. The guys on TV these days would be surprised that engines and cars are kind of complex, and you're not allowed to "leverage" horsepower 40-to-1 like you apparently can in the financial world. Wouldn't it be great if you could be sitting at the tree and just "leverage" your engine up from 200 to 8000 horsepower? Cool!

There are a few comparisons here on the forum of the Gonk and DD and EA a ways back, but mostly I always look for real data and/or timeslips to compare against, in advance when I can do so.

Hopefully it is helpful here and there, just one more piece of advice, and I learn a lot from when it doesn't work as well as it should.

I am a USAF Weapons Officer and later instructor.

It's our advanced airpower tactics school, similar to Navy Top Gun in training and intent, but a major difference is ours is 6 months long and theirs is 6 or 13 weeks, I dont remember.

Long story even longer ...

We are taught early about "5 dollar words" Basically there is a long list of words that you are told that you cannot use. If you do you pay 5 dollars.

As the mission of the school is complete air superiority and air and space dominance, the 5 dollar words are associated with staff work, professional education, sexual connotation etc. For example, a staffer would run a computer, but a iron-jawed warrior, would never leave the fight for staff work, so how could we even acknowledge the word?

But, you may need to SAY it, so we used to use "Gonk", short for Gonkulator and it is why I called Werby's creation what it is a few years ago.

5 dollar words may sound silly, but I am sure you have been in meetings where people get "diarrhea of the mouth" and start saying things that dont make sense or arent 100% clear.

By using these words during training, and in my case paying a TON of money in the first month as a student, you learn quickly to think before you speak.

Sorry for the long explanation, but I figured you'd enjoy where it came from.

If anyone is interested in reading about the two schools, here they are for shits and grins

Would that be like Collywobbles and Simper? Would I owe $5 or $10?

Although those two arent in my vocabulary, they do sound feminine enough to say if either applied to you, yes you'd owe...

How much is irrelevant, because ASKING how much adds another 5, so you always round up when in doubt, accidentally overpaying means you were just unprepared.

You can have your meeting interrupted by the noise from open header NASCAR engines.....

And then a few minutes later have the meeting interrupted again by the noise from open header F-16s.

WAY cool.

Wow, it's amazing how accurate this program is, great job. Keith Craft builds these engines exactly like mine all day long, and has run countless engines on the dyno with my exact setup. His estimates were appprox. 610 H.P. and 620 Tq., based on often repeated real world dyno results of identically equipped engines. Amazing! Thanks so much, I can't wait to get this engine into this little 2250 pound (wet) car and see what it'll do. Should be fun!

Its a wonderful place
