my 580" motor, with more head and cam and compression did'nt make that much power...thats awesome!

Re: 512 Low Deck Dyno Results - 04/12/12 01:59 AM
They are great combos and take about all the head you can throw at them.
For dual purpose cars I like a little tighter spread and phase it a bit earlier just to get the torque peaks to come in at a more street-friendly RPM without compromising the head flow.
You give up a little power way up top but the torque still stays "Massive"....it's just 'all-in' a bit earlier in the Rev range.

Pete,
Wow! That's a bunch out of an engine like that. You prefer the 440-1's over the EZ heads? Any reason?
The reason I ask is we have a 512 RB we run on pump, and it is a beast, at least to us anyways as we close in on the 9sec barrier. Just curious if maybe we picked the wrong heads, or its all the porting you did on those. Yours peaks right where we shift now at 6300rpm...Easier on parts and doesn't seem to hurt our ET.
Could that engine be run at that compression on E85?

Great numbers! How do you think it would do with alky, and a 110 centerline? Mine came in lower (528 cubes though plus the Alky). I had peak torque by 5,000 and shift at 7100.

Nice numbers. I currently have a 511 in my 3000# Duster. The best I have run with it is 10.00 @ 135.26 mph. That was at 6100' corrected elevation.
My set up is: 4.25 crank, 6.535 length rods, dome pistons that make 14.3 compression ratio, 440-1's touched up by Dwayne Porter(no porting), ProSystems carb(90p90s jets), timing set at 36*, 2" Hooker fender well headers, 1.6 Indy rockers, Comp cams roller cam .631/.631 272 in/280ex @.050 lobe lift .421 installed @ 106. The total lift is .672. I would love to get mine on a dyno to see what it actual makes for power.
Maybe I am missing something. Any suggestions appreciated.

There is a lot of power in finishing the porting work . Go to a 2.25 intake valve, full port, and a cam like they are running. Up the compression by cutting the heads. You can cut them down to 64cc if you need to. Should make an honest 825 to 850 hp with the right headers. It might work well to make the headers you have into step headers 2 to 2 1/8 to 4 inch collector with a total primary somewhere around 32 inch.
Posted By: AndyF
Re: 512 Low Deck Dyno Results - 04/13/12 02:54 AM
You don't need a dyno to know how much power you're making since you have elevation, weight and mph. Those three things will tell you the power that you're making.
If you want to make more power then get the heads ported. That should be an easy 100 hp with your short block. You will also need more valve lift if you want to make more power, but as lift goes up, so does the cost.

Very nice numbers.
With the low deck and .471 lobe x 1.6 = .753" lift what lifters are you using? (offset intake seat?)
What do those Indy CNC 325 (2.19 vavle) flow? I think Indy claims 375cfm, but have you tried them on the BEST flow bench?
What was the torque peak rpm? Your table seems to start after the peak.

I look forward to the results. It should haul the mail !
Are these the same heads you ran on the old 499 CID?
Sorry it took so long to get back with all of you, The headers we dyno with are a very old set of hooker race headers with adjustable primary lengh, 2" tubes and there 3.5 collector. The primary tubes are as short as they will go. This block is a 230 one with pro gram steel billet caps and hardblock about 1/2" over the freeze plugs. It was one of mine that was a spare for my Super Bee. We do not use gridles. They are the same heads the customer had on his 499. The bob weight was not ultra light, steel rods and heavy pins. The camshaft always works well that we used, we have a series of them and they make good power. I dont have a dyno sheet with me for peak TQ, maybe Jim will chime in with that. It was stiil rich on the dyno sheet I posted, but the customer whats to tune it the rest of the way in the car, it has a hood scoop that sealed to the carb. The 440-1 head just works so well that is why I like them, we have combos with unported heads 4150 carb and hyd. cam on pump gas that with make 650HP, Flat tappet, little more compression on same deal 700HP all low decks. Like I said these are great engines, just remember its not one magic part but the combination.
Sorry Jim, we did not flow test this pair, Indys numbers are about 10 high from our bench, we used comp 829-16 lifters, no offset, We did install 2.25 intake valves this time and our valve angles. No other work was done on the heads, very basic good build.

Pete if its not giving away some speed secrete what is the purpose of the rubber spark plug boots and clear tube connecting the carb bowl vent tubes together. Is that to equalize the pressures on the fuel bowls?
Posted By: Savoy1964
Re: 512 Low Deck Dyno Results - 04/14/12 11:46 AM
I noticed a little fuel coming from the front bowl the tubing allows it to travel to the rear without affecting anything I use the spark plug boots and tubing to allow the hood to close without hitting the tubing.
Thanks Steff hope it does I can't wait to test it out should be installed by this weekend unless this cold gets the better of me.

Could that engine be run at that compression on E85?
IMO it should be just fine.
I run my 511 low deck at 13.5 CR (68cc Indy 440-1) on E85.
My heads have some old Muscle Motors porting, showing 355 cfm on their bench. So they are not as good as the CNC heads on Savoy1964's engine. 9.2 at sealevel and 3225 lbs.

Re: 512 Low Deck Dyno Results - 04/15/12 02:24 PM
When you changed to oiling through the push rod did you keep the spray bar valve covers? I am thinking about changing mine over to oiling through the push rods and still using the spray bar's as well.
Yes its a Indy intake, 4500 type, this engine is not pushrod oiled or using spraybars. It oils with the std oil lines to the back of the heads. No offset lifters, no extra port work, not a lot of valve lift, just a good basic engine. Should last all year or more on the valve springs also.

Re: 512 Low Deck Dyno Results - 04/15/12 10:22 PM
Greg: Thanks for the reply post. I guess I need to have my heads ported and a bigger cam. As far as cutting the heads, my valve to piston clearances are close now. I am about to the max with the car chassis and rearend now. Car needs too many updates. Need to find a different car.
Thanks again. I really appreciate it.

Yep, it is making good power. I'd like to do a side by side test with my 514 just to see how it stacks up.
Andy that sounds great, What parts are the same between the two engines, the crankshaft stroke?

Re: 512 Low Deck Dyno Results - 04/18/12 04:53 AM
I don't think my 514 shares any parts at all with this 512. Mine is 4.440 x 4.150 with EZ heads. The power is similiar on a different dyno, but everything else is different.

Does anyone have the weather like for that run? (June 8-10, Gateway, time)
Heat, humidity, elevation 400ft?(atm pressure) all play a role. Track Weather History - DRR

I am trying to compare my 511 at 3250 lbs

I have been quicker and faster than him at about the same weight (depending on fuel I guess for that day) with a crappy 1.44 60ft. I have 60 more cubes and he has over a point more compression. I certainly feel I have more left to go in my setup as im sure he does!
not bashing or trying to get things riled up but I am hoping to get 800 on the dyno soon then prolly sell the engine fresh and start over (I get bored easy though)

Your car is running good. And should do a little better if you lean it out. The lack of sixty foot performance is holding it back. I don't know if it is converter, 1st gear ratio, or what.
Like I said, IMO your engine is making about the same as mine, and I am happy.
Posted By: gregsdart
Re: 512 Low Deck Dyno Results - 07/11/12 01:17 PM
That is solid performance out of a stock block build. The big body isn't helping you, and it will be interesting to see just how much you pick up as time goes by. The other part of the equation is always chassis driveline efficiency. Just how close to perfect your trans/converter/tire/suspension combo are also affects how good the motor looks hp wise. So I only see it going faster over time
Posted By: Savoy1964
Re: 512 Low Deck Dyno Results - 07/11/12 01:24 PM
Thanks for the comments I am happy with the performance. Running on SS springs (02-03) is most likely a limiting factor in 60ft and I don't want to go any bigger on tires 29.5 10.5W, bigger means tubbing.
Its an early 60's pushbutton trans and I am not sure what the first gear is.
Posted By: gregsdart
Re: 512 Low Deck Dyno Results - 07/11/12 01:29 PM
Pretty sure it is 2.45 low. Never heard of a different ratio for a BB 727. Good luck with the suspension, I am betting you can make it work better. The tires ought to be sufficient based of 440JIMS, performance.
Posted By: Savoy1964
Re: 512 Low Deck Dyno Results - 07/11/12 01:35 PM
Just did a little research and 2.45 is the first gear. I just need to do a little more testing I will be at Milan this weekend have to play with jetting and see what I get.

Re: 512 Low Deck Dyno Results - 07/11/12 02:02 PM
Just throwing this out there,you may want to check into how much convertor slip you have on the top end
I did not see anything posted about your rpm crossing the line or any information about your convertor.
Another thing that might affect your performance is the difference between your ignition and fuel system,and the systems used on the dyno.

Re: 512 Low Deck Dyno Results - 07/12/12 03:09 AM
I have found it hard to tell the exact rpm through the traps but the shift light will usually com on just as I go through the finish so approximately 7200-7300
