OK folks, I am posting the dyno numbers from my 512/440Source engine build that I just FINALLY had dyno’d on Friday.  I started this project over a year ago and it has finally come together. Kudos to Ron (firefighter) for putting together this great build and for PUTTING UP WITH MY ENDLESS QUESTIONS!  cheers

I am quite happy with the results. All dyno work was done at Ray Barton Racing Engines as they are about 10 minutes from my home. It was Ron’s idea to have a professional shop do the break-in and it was a wise move. I have too much money tied up into this build to take any chances. The cost for the break-in and 3 pulls was about $570.00. Well worth the investment in my opinion.

Here are the basics:

68 “D” 440 block bored .030 over

-440 Source 440 >> 512. (4.250" stroke/7.100" rod) factory balanced
-All new Clevite 77s main bearings, cam bearings, etc.
-New Hemi oil pan, oil pickup and 440Source windage tray.
-New Main Caps and ARP studs
-New 440 Source Stealth Aluminum Heads
-New ARP 12 point head bolts
-New Engle K60H Cam and Engle Lifters
-New Crane Chrome Moly Pushrods.
-New Crane Rocker Shafts
-New Stock MP rocker arms
-New Crane 3 bolt double roller timing gear/chain and cover.
-New Proform 950cfm Race Carb
-New Fabulous Fabrications Dubble Pumper Fuel Lines
-New Holley Street Dominator Intake
-New MP Electronic Ignition Conversion Kit
-New MSD Blaster Coil
-New FireCore 50 8mm plug wires
-New Summit Harmonic Damper
-New Melling high volume oil pump

Here is a link to a video of the run and some shots of the motor on the dyno system. The motor ran perfectly with great power, no odd noises, good oil pressure and NO LEAKS!!!

Sweet, bookmarking this page for when i do my 440>512 stroker. Seems like a great street engine with all that hp/torque at low RPM's. Congrats  2thumbs 2thumbs 2thumbs

Be sure to post up some video when ya put it in

Hmmmmm.....I am building almost the exact same combo and I was hoping to see at least 50-60 more HP produced.  However your torque numbers are just fantastic.  2thumbs

I wonder why so low on the HP? Because I have read numerous times about waaay less serious combos than these making 500HP.  scratchchin

I wonder as well. 

The 496" was a similar build in the beginning, but using factory iron "452" heads with oversize valves and a couple of basic porting tricks done.  It made 514HP/598Torque.  Could be different dynos??  After bolting on the Eddy's, the butt-o-meter was telling me it had to be making at least another 50-70 more horsepower.

According to 440 Source the compression is 10.5 to 1. Keep in mind that I took these heads out of the box and bolted them on with NO porting.

Ron told me that my cam was small hence the low HP. My wife has been telling me the same thing for years. hah

Barton's son was doing the dyno and said the torque was fantastic and that number is what I should be looking at.

I was hoping you didnt do any porting but I still figured it would be around 550HP. I wonder if any HP could have been gained up top if the timing had been advanced to 36 or 37.  scratchchin

Your engine is still a torque monster! Congrats!

Looks like a good street motor. Awesome. Hope my 496 turns out just as good.

Mike, thanks for posting the dyno sheets !  2thumbs  Barton is right....the torque/bottom end power are the most important numbers in this type of build and yours has LOTS....and then some !  icon_smile_big

That is a beautiful flat torque curve.....geez 580 ftlbs at 3500 rpm is Killer !  devil

For the guys asking about the HP numbers....they are right where they should be. The cam profile was specced based on streetability and vacuum requirements for power brakes. This engine will idle like a stock 440 and light the tires up at will from just about any speed ( be careful Mike  icon_smile_big)

The Source heads flow ~250 cfm @ .500 lift so this motor is using all the cylinder head can give it. The cam was specced on a wide 112* lsa to reduce overlap, spread out the power and make for a stockish mellow "idle". This car is going to be a real wolf in sheeps clothing....can you say sleeper  naughty

If Mike wants another 100hp a cam swap and some head porting is all that would be needed. With 3.55's and a 2500-2800 stall, this is the perfect build....inmo  yesnod

Throw some slicks on the car, heat them up and this baby will run 11's....no problem.  icon_smile_cool

Ron, that's exactly what I was going to say... Grin

I'm not sure what size headers were on the motor as Barton supplied them. They did comment that they were tti headers though.

Nice. And that is almost identical to my build except for the heads. I had un-ported 84cc Eddys. The motor made just a bit more power: 543hp / 612 fpt. The cam was also an Engle (k62 intake lobe/ k64 exhaust, 244/250 duration, .540/.557 valve lift, 110* lsa).

Per Ron's advice I also added 1" carb spacer for the dyno.

NJ mfr426!!  Nice numbers and thanks for posting.

I am really starting to see a little of Ron's soul in most of the new stroker builds documented on this great site!  All the members here provide great info and support but Ron always seems to provide that little something extra.

Thank you Ron!

Chris, your bracket gave me the idea for mine. It took about an hour to fabricate but it looks pretty good IMHO. It fits nicely under the air cleaner too.

Ron's attack plan for this build was right on. I drive my car to work once a week and like to cruise. I'n not a racer. I have power everything on this car and didnt want a true race car. I wanted something reliable that would give me good brakes and could fry the tires at will. I also like reliability and wanted something low maintenance. With that said, once I on the frame connectors I will take it to Maple Grove and give it a run just for the hell of it.

I hope to install the motor within the next 2 weeks. I have to pull out my trusty 383 next and then just drop this in. I'll be certain to video a good smokie burnout for everyone.

For those going to Carlisle, I will be there again. Ron, I HOPE YOU MAKE IT as I have a case of good beer with your name on it!!!

Thanks for the kind words Andy.  icon_smile_cool  Mike deserves a lot of credit as well because he selected most of the parts and did his homework....i just fine tuned the build for his application.  Wink

Not everybody wants or needs a 6500rpm redline screamer. In Mike's case he wanted a torque monster with zero maintenance and this is what he got....oil changes and spark plugs are all this motor will need to provide years of trouble free service.  icon_smile_big

Mike, i for one will be looking forward to that Video.  drool5  I hope to make it to Carlisle and have a few cold ones.  cheers

Ps. I don't know if you've seen this thread but if you haven't "bulletproofed" the driver side motor mount....now is the time.  big thumb up

Ron, that's another good tip! Since I have everything out of the car now, I think I'll add this added support.
