That's awesome! Congrats!

Interesting that your torque peak is a bit higher rpm than mine. My motor was a bit more square - hp/torque being almost equal.

I wonder if it’s the bigger intake. Everything else in our combos are super similar. I did switch to a 1.6 rocker which gave me a few more degrees yet and .683 net lift.

Yes you definitely do and there's another who knows how much lurking there. I never get why guys use the baby carbs on motors like yours unless it's a heavy turd......GREAT numbers....

I ran a 337/adapter vs a 440-2/adapter on a 540 years ago.
With the Indy intake the tq peaked at a slightly higher rpm.

On that motor, there was a pretty big disparity in HP between the manifolds, with the 440-2 combo showing 40cfm more air being used at 6500rpm.

However, on a milder 572 street/strip build, tested with the same 4150 carb and spacer, the difference between a 337 and a 440-2 wasn’t as big(15hp), and it didn’t really change where the peaks occurred.

At the very bottom of the pull(3800), the 337 was up almost 30ft/lbs.

A picture of the dyno sheet would be nice.

Congrats on the number. I said 700 would be easy; but you went well past that.

Man, that is impressive. I have a 512 with less compression, less cylinder head, less cam, TF intake, 950 Thumper, 1 7/8 headers that is probably 115 horsepower down from yours.(491 at the tire. 625 crank? maybe?) I've been kicking around the idea of upgrading the top end; heads, cam, intake, Dominator, headers, and this dyno session makes it a lot harder to NOT do it. Although I'm still weighing how it would act in a heavy car with a clutch and a 3.54 gear.

Jim my problem is it’s saying my files are too large. I’m not sure how to change that. I’ll be getting the sheets today and will do my best to post what I can

Thumper I’ll be getting a hold of you soon. I may still see what you can do with this 1050/4150. From 5500 up the 950 was pulling 1.9”
So it needs more carburetor badly. I’m sure a dominator would easily push it to 760hp.

What I do to downsize a file on my phone is email it to myself, and choose one of the smaller size options before I hit “send”.
Then use the new smaller version to post.

Where exactly was this reading being taken from?

Was there an air turbine being used?

Duane I believe it was the back of the carb. He has a air hat but doesn’t use it.

I think I have the the picture posting figured out.

Raw numbers

Ok guys hopefully this satisfies you. I may have missed a page or two so let me know if there’s anything else you’d like to see.

This should be a little easier to see.

Excellent result, our 589 pulled the same 1.9>2.0@5900>6000 with a 950HP, we made max power @only 5500 at 33 deg total and NGK 7's although it pulled to 5900 only losing 2hp. I would go straight to a Thumper BLP Dom with yours with that CR/cam, wouldn't mess with that 4150 if you have room under hood with a spacer and if you got any money left

😂 I may have to wait a few paychecks. And I am not sure what will fit under a fiberglass six pack hood on a cuda. I also have to figure out clutch and rear, possibly a cage, driveline, wilwood front brake kit, and more I’m sure 🤣. But I’ll get there as quickly as I can.

Very nice results. I bet that put a smile on your face. The torque curve is nice and flat too. Looks like it might be able to be fattened up a touch, but who knows. I have a 400-3 that i hand ported the plenum for sale. If your interested PM me.

OR a 1000+ cfm 4150......

That’s why I didn’t bother jetting it up a touch to get more out of it. I knew it needed more carburetor so there was no point seeing how much more I could get with jet changes.
Can you pm me your number dom?!
