That was the tenth pull only and we stopped as motor was heat soaked, we kept it around 170 water temp and 150 oil I think it was, oil curve was flat!

Nice!

Congrats, let us know how well it picked up!;)

Congrats!

Wow! Awsome! Congrats

You've come a long way baby! :beerchug: :faint: :wife: :police: :thumbup:

good job......that thing should get some pretty good fuel mileage, can anyone say a reverse LS swap?....but that is another story.;)

Can you post your pulls ?

Here they are, one is the EGT sheet, The afr was not lean, we looked at the plugs.

Who's dyno was this?

Do you have the graph too?

I take it the AFR is not correct as you would have not made that kind of power.

Can you post your build so I can look your combo over?
Thanks

Was more timing tried?

No graph, dyno was at engine guys shop, local.
Brian we started at 30 after 3 pulls , we checked lash, then tried 32, fell off more n dropped a lot after peak, so then we went to 28, and it was better, carrying it out n dropping not as much, 26 was the last pull #10, motor was plenty heat soaked at that time, we kept it at 170 water n 150 or so oil. There's more power in it yet, If we would've cooled it down for a couple hours, I know it would've went 660 easy.

Were jet changes made? With more timing it probably wanted jetting.
I would definitely jet up with it in the car to start with imo.

We were going to, but pulled a plug n it looked good, so that's when we dropped timing n still made pretty much same power, but carried it out better without dropping near as bad. The EGT'S Were pretty much the same with more timing, so that told me it probably wasn't lean, plus the plugs were good.

The Tq looked a bit lower than what I would expect and I don't know the rest of the specs??... degreed & jetted?... I see degreed to 106

I did a 462 street engine with a much smaller cam & for the most part 90 less hp but about the same peak Tq

Overall I'd say success Mr. Darby!

You should have a fun season.

Thanks!!
What did u want to know Jeff? The Specs are on first page. Cam was a custom mike Jones can for this combo, degreed in at 106.4. Jetting was 92 square. We didn't even touch the carb, not even a mix screw!

Yeah I missed the ICL on your 1st post...

Pistons, etc whole build...if you don't mind?

Is that the same custom Dominator I built you back in 2011?

So you had 1 dyno day?? good that you got it on there in the 1st place.

400, scat 4.25 forged crank, callies rods with L19 bolts, Mahle dished pistons , coated rod ,cam bearings,4.185 bore, standard 1/16/3/16 ring pack.Program main caps, SD Brace, Cam is 188/190 @200..PAC 1289 springs ,2.0 IH, 250 seat/ 640 open, tool steel retainers, titanium locks.

Nice build, you have the heads ported to 325 cfm?

Congrats, that's some impressive numbers, I started to go with the d-ports but ended up going with High ports instead so now ya have me curious on what my junks gunna make lol again congrats should be a fun ride for sure......

Heads flowed that on a tight bench, on my friends 600 they flowed 347@800, YOU can do a search of before and after pics, the heads came from someone else n were ****ed up so I sent them out to be fixed.

Thanks! I'm curious also on yours! u have a lot more flow n comp I believe.

Had my share of repaired KRE's too...

Yea, there 368cfm high ports on 14:1 461 with 277/288@50 .485/.471 lobe lift and 112 lobe sep with harland sharp 1.65 rockers, im still impressed by your set up ive shared it with alot of my buddy's that's on PY, cuz was trying to talk couple of them in to buying a set of Kauffman D-ports, I never intended on going as far as I have but when I have people running that mouth I just kept buying stuff lol like full Calvert suspension and msd power grid system think I went a little over board but its there for the future now LOL

Impressive Darby.

Honest 650 hp on pump.
