       We went to Kidd performance in Twin Falls Idaho Saturday. Bolted the 470 up to the dyno and after break in had some pleasant realities hit us right between the eye's. We did eight pulls,,, with a best of 620hp and 600 ft lbs of torque! (corrected) All on 91 octane Chevron premium gasoline. 105-108 volumetric efficiently all the way through the pull. Dyno pulls and build will be posted soon. This thing was worth the headaches. More to come,,,, Kyle  ;) :yesnod:

Very nice. Looking forward to seeing the build and numbers. I'm seriously thinking of doing a 470 build :scratchchin: (hell, I just bought a block so who am I kidding. I will be doing one. :yesnod:)

Holy crap!!!  I'm running a 470 but haven't been to the dyno with it yet (in fact was only able to drive a few times) I can only hope for so high!
I was guestimating 500 hp 500 tq on mine... :)
Gotta get to a dyno, now that i live in the big city!!! LOL

Please post your combo :)

That's great news Kyle.  :2thumbs: I just got an e-mail from Scott and he's tickled pink with the results....damn impressive for a 470 on pump gas.  :cheers:

Glad to hear the Firecores arrived in time for the dyno thrash.  :icon_smile_big:

Looking forward to the build details and dyno numbers !  :coolgleamA:

I am a little disappointed after seeing the actual print out. I was wrong about the torque number, only went to 590, not over 600 as stated,,, Sorry!  :eek2: I thought we would get from idle up numbers and as you can see here that did not happen.  :icon_smile_blackeye:  I will inquire why we did not get the whole run on the print out.The build is yet to come. I need to gather all of the correct information as my memory does not serve me well at all. :shruggy: More to come Kyle.

That's still nothing to cough at!!!  LOL
TQ looks pretty flat any way!

Why would the VE be over 100% ? Forced induction ???

I wont claim to know why the efficiency numbers are so high, however I made the cam choice based on those numbers. On the desk top dyno I kept tweaking the cam numbers until I reached the best numbers for the bore, stroke, compression, and heads we were using. I would say everything is working real well together. We are normally aspirated, Demon 825 carb and race mufflers. Kyle

did they give you a graph also?? to me the graph shows peaks and dips (flat spots) better for telling if you've got steady power or peaky power and to tell if the torque falls off too soon for the HP to take over, again, just easier for me to read than reading a column of numbers

Kyle, those are impressive numbers for that combo. The wide lobed 114* cam and low (pump gas) compression are why it didn't make over 600 ftlbs. Trust me, you won't be able to feel the difference between 590 and 600 ftlbs in the car....or on the time slip.  ;)

The torque curve is nice and flat....power everywhere which is what you want for a street/strip build.  :2thumbs:

Question on the AFR, if a WOT run it looks a bit lean to me? Shouldn't it be high 12-13's? Or is low 14's the target WOT AFR for these engines?

I agree Jim, it does look a little lean up top.  :yesnod: Personally, i'd be happier with high 12's -low 13's on the A/F's but on the dyno you can get away with a slightly leaner mixture and still be safe. In the car is a different story.

IdahoGrumpy, if you don't mind me asking, how much did it cost to dyno the engine? I have a 383 build going togeather and live in Boise....  I would love to dyno the engine before install and would make the silly short trip to do so!

Will they break the motor in on the dyno as well?

Thanks!

Kyle what cam is that with 114lsa giving those numbers?  Is that a custom grind that you designed?

idahogrumpy

 :icon_smile_blackeye:      Sorry people been busy and still have not got all of my information together. Again my memory is not treating me well. We had so many different plans and ideas about this motor that my facts got a little screwy. This engine was put together over several months and the bulk of the parts were ordered by the engines owner about a year ago. So here is one more little piece to our build. The cam card. Yes this was a custom grind. The cam specs were tweaked by me on an engine Dyno simulator. This is a solid lifter cam. The engine Idled very nicely at about 850 rpm. 112 lobe centers not 114 as stated earlier. :brickwall:

I have not spent any more time with the engine tune as it is going to be pulled from the car it is in now and put into the owners 73 Scamp over the next few weeks.

ah Engle.  Nice!  I want one of their cams so bad, but I'd have to rip out my current cam, then worry about the zinc in the oil, ect.  My "slow ramp" cam probably lets me get away with lesser oil.

Cheers,

What are we in John Force's garage here and mums the word!   :slap:   ;D

What gives, we want more details on this build, as making 600+ Hp and almost 600 torque on a 470 pump gas engine is extremely impressive and some of us would like to achieve this also!  :cheers:

Looking to build the same type of engine and would LOVE to get 600 horsies out of a 470 engine.

Who can  confirm what Heads this build was running, ported and polished or out of the box and what compression ratio?

Thanks in advance!  :cheers:

Alright folks! My Father built this engine, so I will get on his butt. I am pretty sure they use indy heads! I will give him a call now.

nice street motor  :yesnod: :coolgleamA:

I agree and I want to duplicate this build!  ;)

What is the standard bore on a 400 ci low deck 470/471 build as it seems like a great way of making some big power on a budget, utilizing one's 440 crank.

Also, what can I expect to pay for a bare good condition 400 block and what year blocks are the best?

Thanks in advance.  :cheers:

That would make sense making this type of SERIOUS power, please get us specifics on the exact heads, compression ratio, etc. and thank you!  :cheers:

Well I spoke with Scott (the owner), he said it was Indy EZ heads (No Porting), high rise Indy Intake, Indy Rockers, 870 Race Demon CARB, 440 source stroker kit, 440 source girdle. The piston where installed even with the deck. Thus creating .040 quench (Close to it). Scott told me to let you guys know to watch your bearing on the 400 stroker builds, make sure you radius them for clearances.  I am sure IdahoGrumpyBear will post later!!
