That's the worst part about a dyno mule. The deck height & heads need to be pretty identical & even then you can't always expect everything to just bolt-on. Seems like most of what I do is very specific and for one specific application. But you're learning some valuable data & doing it right. It just isn't always easy as people think it should be. Great info
These are some of the best testing I’ve ever seen I have a 496 similar to your Dyno mule and I am putting together a 540 that will be similar to this one. We do have Brodix ported heads but similar size anyway it’s been very helpful. Keep up the testing!!
Eric, great testing and video. I still always go with a Brodix intake, but I run al Brodix casting, so I go with the intake the heads call for. I have the intake machined to match the heads after they're machined. This sbc I'm doing the heads are 13.5° oval port, and for the first time, I'm going with an All Pro valley cover, and the intake is CID and they make them pacificly for the company doing the 13.5° Brodix 2300 symmetrical port because it's a little different than Brodix 2300 they offer.
After milling the head deck surface, you need to correct the intake face on the head. The Big block chev is at 90degs. Just recut the intake face until it cleans up fully. And then run an extra thick intake gasket. So now any intake will bolt right on. NEVER cut the intake manifold.
Dang huge difference on hp difference also Facebook is messed up right now I don't know if they fixed it yet but I can't log in and a few of my friends can't neither so just to let you know
Bit off topic Eric , I see someone fitting Promaxx cnc ported heads to a 440 BBM, would be awesome to see a review on these, lovin the vids ,especially the BBM stuff😊
looks like power still going up with dominator, where does it roll over, where would you shift NICE how was the match at the top of the ports, bottom not so much :)
i was on a live feed posting about a totally different situation and story and my comments went to your channel and nicks garage youtube needs to be cracking down on chineese cause i have info on the case im not supposed to have and its linked to a special chineese interest so none of my comments are hitting this individuals site and some chineese hacker is shuffling them to other posts ! as crazy as it sounds its a fact

This 540 is very impressive 875 hp is some serious hp just think what it would do with a pro charger. Very good video. Oh yes do the tunnel ram.

On flat mill it’s not really necessary
2 dominators on a tunnel ram would put you over the 900 mark
Great test. Well done Eric.
Just in time ❤
Yeah tunnel ram
man, you do some nice work. if only you were closer to me i would love sending you some parts.
Thank you again for the terrific information.

Nothing better than a nasty Big Block Chevy! Frickin sweet! Thank you sir!
I wonder what the vacuum is under each carb at WOT
The profiler tunnel rams the shit, Darrin Morgans design
That's one hoss of a 540 right there
Would be nice if the engine specs are kept in description for easy refrence.
Test Afr 290 ovals
I'm thinking narrowing the cam lobe centers to maybe 108 deg. would build more mid range without sacrificing the top end.

how was the match at the top of the ports, bottom not so much :)
Thanks
Well, if i had a 540 i might b interested
Nice!
Eric, have you ever tested a bbc profiler Sniper Jr. Intake?
I talk about it in the video.
So close to 885 hp or 100hp/liter.

You have a bigger dominator? 900hp through a 1050 carb you are probably pulling 2" at wot.
