According to Wallace racing calculator, 3400lbs @ 130 MPH is 575hp....
Sorry, didnt notice the "440" in signature..

I'll be really surprised if it doesn't make north of 650 HP and 620 Ft lb. of torque with those parts What brand engine dyno and how much elevation, humidity and barometric pressure on the dyno are you expecting Good luck

Whose dyno?? On a few dynos quoted on here, I'm sure it would show over 800...
I'll wager...132 to 133 mph
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.

I can't see it making much more than 600fwhp, not enough head/small cam for them cubes to make mid to upper 600's in my opnion.
My mates 440 Dart with 12.7:1, Eddy std port MCH 325cfm heads, DC.590 solid purple cam, 1050 Dom., Victor int...just managed to hit the 600fwhp mark according to best mph/weight. and that cam was done at 6600rpm, car would slow if he shifted it over 6400 through the gears.

The latest generation 440-1's come with CNC'd chambers, and with the right valve job and bowl work can flow quite well.

Do you have any of those #'s , I based my guess on older none ported 440-1's & the low lift cam.

For sure the low-ish lift of the cam(for this combo) doesn't play into the -1's attributes, especially earlier ones.
The last set I did(with cnc'd chambers) flowed 297@.600 ootb, and about 340@.600 after proper prep.
I feel like the 10.5cr is a bit low for the basic combo as well.
If the heads were similar to the last ones I did, and I had it on our dyno here, I'd be looking to be in the 650+ range........ It is a 511 after all. I'd have used 1.6 rockers for a cam like that in this type of build.

LOL We have (42) SAE calibrated engine dyno's. Our Dyno's have to be calibrated because of all of the OEM prototype developement & production work we do so our Dyno's are usually about 15% less than the average Joe. Believe me, you walk into most single dyno engine shops & say you want to make approx 800 HP they can make it make the number pretty easily when it is probably making more like 680ish HP.

Cant see that combo being anything much over 600hp for sure of if it even got there. But as been pointed out dynos are dynos and not all of them spit out the most accurate of results for sure. Id say at Mountain View that combo would struggle to see 575, that's where I have my most recent dyno experience.

I guess whatever numbers that dyno throws out, whats more important is knowing where the power is being made with the combo and then perhaps some gearing changes may/may not be in order.
As a guide, with an on track 620fwhp/3400lbs the ticket would look something like this> 60 Foot E.T. : 1.43 1/8 Mile E.T. : 6.48 1/8 Mile Trap Speed : 104.88 1/4 Mile E.T. : 10.27 1/4 Mile Trap Speed : 130 with it in the teens? if it 60's better than shown above. according to my calcs.

Since its a Comp cam, I'd be interested to know what the lobe numbers are....... And I assume you're running 1.5 rockers??

Sorry, typo it was late. 265 and 270 @ .050 I intend to spin it to 6500-7000. Thanks. Be lucky to break 600 hp, probably more like 575,??? That cam @ 265 intake is smaller them the MP 590 @ 271 @ .05 you were using. But with the new engine you will be making a lot of torque. To make HP you need to spin them a bit. Your not going to be able to spin that new engine very high in its hp band with that small of cam. It will be done by 6000 rpm. Typical 500" motors with your comp can hit around 600 HP with the mp 590, your using a even Smaller cam.

I am guessing your goal might be 10.01 et? Just a thought, has anyone had good luck with 1.7 ratio rockers and beehive springs? That would get you .630 + net lift on the intakes, and raise the net lift everywhere, which i would think should be well worth the trouble, and cheap power to boot.

I doubt the power increase from a ratio swap would corolate to the $1100 price tag.
If I had $1100 to throw at it, it would be on a roller cam, lifters, and springs.

We always do this at work with alot of the race engines we build. Sometimes it's $1.00 per person per guess, sometimes $5.00 per guess. Winner gets the pot. We did this on my Hemi when we dyno'd it. So many were so close but it did make more than everyone was expecting.

Anytime a hot/bigger motor runs a 4150 type carb they CAN go very rich due to the added velocity that larger cubes create and are more sensitive to tune from my experience. The RIGHT Dommy will smooth that right out..........

The AFR read out says lean, the BSFC says a little fat up high. Test,test and test some more until it goes slower or looses power, correct Maybe it needs a slightly bigger high speed bleeds I agree on a bigger CFM carb. to help eliminate the manifold vacuum increasing restricting the air flow into the motor

This has been debated / argued before, but you cannot tune a carb by BSFC #s. BSFC doesn't tell anything about the air-fuel ratio. It's simply a measure of efficiency of the amount of fuel used to make the power recorded. EDIT: LINK to article on BSFC vs Air-Fuel Ratio...

... It was a Q950 Stock jetting was way to rich... How much did you have to lean it out from the standard tune? I'm a little surprised you said it was too rich from what I recall the out-of-the-box settings are.

Test,test and test some more until it goes slower or looses power, correct Maybe it needs a slightly bigger high speed bleeds I agree on a bigger CFM carb. to help eliminate the manifold vacuum increasing restricting the air flow into the motor I agree! Of course the customer will add a air cleaner and full exhaust and that will change things to so no reason to chase a couple HP onthe dyno and like most guys he will do a little tuning once it's in the car. Reliability and driveability are more important. Just for example, a A/SA Max Wedge on our dyno will make 595 hp and run 10.20 at 3400lbs. So how fast would you think a 3600 lb 4 speed Road Runner would go ?

... It was a Q950 Stock jetting was way to rich... How much did you have to lean it out from the standard tune? I'm a little surprised you said it was too rich from what I recall the out-of-the-box settings are. I believe it was 4 front and rear I am not surprised now by this . I had to pull 4 or 5 jets out of the front and maybe 2 rear when I went from 440ci to 505ci. Motor just works the carb harder especially if carburation is a little undersized . Tex PS : my 505 with a hair more comp and bit more cam makes 600-620 FWHP . With a 4150 carb , mufflers and exhaust to diff . I am not sure this one will go too much more .

Yeah, the bigger engine would create more signal than the carb was originally tuned for, whereas a too-big carb would need to be richer to crutch the lack of signal.

Is 3340 the weight with driver? If so then you are making more than 650 hp. That is a little better than I was thinking with those parts. The heads must be pretty good even though they were not ported. Looks like a fun ride. You'll need some wheelie bars if you port the heads! Is the car legal for 9's?

If it missed or half fired, all the oxygen that should have been used up during combustion but didn't goes roaring out the exhaust and right by the O2 sensor which has no choice but to do its job.

IMHO you have the perfect combo, don't mess with it . Runs very consistant, low rpm, should be very reliable!!! If you want to go faster, look to removing weight rather than changing the motor or rpm you run. Guess why i think this way? M Like Greg said concentrate on making the car lighter while still keeping it simple. Man you guys in other countries race fat cars. Even your A Body’s are heavy.

Thanks Andy! The first 1000 feet is spectacular! 1.304 60 foot, 109.5 at the 1/8th but it stops accelerating at 1000’ so I’m trying different converters to get the tightest one I can find and then I’m going to have to do a gear change. My feeling is to should go a high 60 or low 70 at 136. I’m pretty happy with it, its deadly consistentl too. I built it to limit myself to 10.0’s so now I’m past that and legal I will want to go as fast as I can to make it all worth it. Lol I thought about it some more and it might be cheaper and easier to do a cam change than a gear change. If you had a little bit larger cam then it will pull all the way to the stripe and you won't need to change the rear gear. You probably have enough data now to sit down with a cam guy and talk it over. My guess is that you need another 5 degrees of duration at 0.050 to pull to the stripe but if it was me I'd run it by Dwayne to see what he says.

If it was my decision on your parts I would send the heads out this coming winter and have them CNC ported and have the 2.25 intake valves installed to allow more RPM from then on Are you sure it isn't running out of fuel at the 1000 mark? I've seen so many drag cars( of all brands ) that have those issue with no other signs of lost of fuel delivery If you can't jet it up enough to slow the MPH down in the 1/4 mile your running out of fuel, not fuel pressure, fuel volume One of my newer Holley HP 1050 Dominator carb. had one .110 needle and seat in the front or rear and the other one was a .120 seat, I could not jet that carb. up enough at the 1/4 mile track to slow my old pump gas Duster down Once I changed it to .120 on both fuel bowls I could Lots of gremlins out there

I don’t think it’s fuel related I have an Innovate AFR gauge and its in the low 12’s and consistent. With the small cam its a torque combination and it drops off after 5900RPM. I’m at 67-6800. If I shift 1-2 and 2-3 at 5800 it ET’s the same as shifting at 6500 but shifting at the lower RPM makes the top end even worse because I’m not as far down the track. If the plugs show to be rich in the low 12's, I'd lean that puppy out accordingly based on fuel and hang on. With some motors I've worked w/and know about, to a point leaner is meaner and I went faster in the 12.8-13.0 zone than at 12.2's. I've seen dyno pulls of some serious all out n/a motors where max power was in the mid 13's and leaner in some cases...........

So I never got to run the Callies block in the car last year. The new RB intake had considerably larger ports than the unported -1 heads so over the winter I matched both to the gasket and did a light porting, more of a blend, and I took a bit out of the guide boss area. I did quite a bit of work to the 4500 intake to match it to a 1" tapered 4 hole spacer. It's too bad I didn't get to dyno the low deck because it would have been neat to compare it to the RB with almost all identical parts. Same cubic inch, same compression, same cam. Heads are probably a bit better than they were, the RB intake has longer, straighter runners than the low deck intake. The block is more stable, bores are thicker so they stay rounder, but I doubt any of that would show up on a dyno. Feb 17 I'm supposed to be on the dyno with it, different guy than last time so it should be a go. Update on the combo- Callies RB block 4.375"x4.25" 10.5:1,Lightly ported Indy -1's and Indy 4500 intake, Bullet 277@ .050" .640 lift, EDM lifters, 1.5 T&D rockers, Pro systems 1150 Dominator. I'll update when it happens!

Did you make any pulls higher than 6400?
On the sheet you posted, the highest hp number is on the last line.

Can you post or list your AFR with the RPM, AFR and RPM? Some testing needs to be done in the car, my E85 motor ran 2.5 MPH faster in the 1/4 mile shifting the 2 speed tranny at 7300 RPM versus shifting it at 7000 RPM, every other part of the time slip was almost identical, within .0002 ET, up to the 1000 ft clocks

Getting a data log of your rpm during the run may surprise you . My torqueflite takes at least 200rpm to complete a shift , so the actual shift point was more than 250 rpm higher than my Conmand Center shift setting. If you are shifting by a tack light, then add delay to that, raising rpm even more. All in all you have a very good combo going hear! Congratulations on a great build. From my history, if i had your combo, i would be leary of any changes that threaten your consistancy, if you desire ro go rounds.

700 with OOTB -1's and a low lift Solid Flat tappet to me seems pretty impressive!
Originally, I was going to go with -1's when the Chapman MW deal kinda fell into my lap.
Your motor and cam is very similar to my 517 (I run a Bullet HR with 264/268 @.050) but what is your ICL?
Your torque is nice and flat....over 600 throughout nearly your entire pull.
I might have revved it 500 past peak, just to see how quickly it fell off and maybe richened the jettting a tad to be safe. But then again, where you peaked is about where I would have expected and from graphing the torque drop off you can pretty much predict it. A bit more intake lift with a -1 might squeaked out a bit more torque but it still a nice power curve.
Congrats, IMO 700 without a lot of RPM and basically pump gas compression is the way to go for a long-lasting bracket motor. no sense chasing the last bit of HP if it takes raising the torque peak higher and stressing the block further.
