Anyone have good reasons to run this 23 degree vs a 15 or 18 degree boosted application if its no-prep and rules dont matter? Thanks...not being a smartass, just asking.
@@SpeierRacingHeads No doubt...but like you said above, a 13* or 15* would kill it. If class rules didn't dictate their use, then why? I know, to each their own. Regardless of why there's a market for it, you killed it. Keep the vids coming! Love the technical content!
WOW !!!! That's incredible! Pushing the limit !!!!! Knocking on All Pros door !
In the right hands those heads are going to make huge power. Super excited to see what the future brings in the 23 degree world.
That is impressive!
That's gotta be a world's record!
Awesome Work Chad !
Nice job Chad
Amazing numbers
Thats a lot of flow great work man hats off to you!!!
I had track 1 brodix flow 320 ...25 years ago
Unbelievable port development.
Stable and smooth no doubt.
Does it even back-up flowing it at 40"?
Badass work dude!!
no not at 40
@@SpeierRacingHeads Killer work bro! There's a very select few that are on another level.
You are one of them sir!
Nice work! Will the intake gasket seal on a port divider that thin?
Think if saw smoke out that flow machine 😅🤣😂 awesome 😎💪
That'll make some power...
Take a hell of a cam to utilize those heads.
When Darin Morgan himself says to go to Chad Spiers for SBC heads over himself you know you found the top man in the game!
As of right now, and he's only talking about 23° heads. Most top-end machine shops don't spend time on 23° heads anymore. And I'm not hating...
👍👍👍
It would have been nice to keep this under wraps for at least a little while.
💪💪💪💪💪💪💪👍🤠😎 awesome how much ????
Bad chad
Is that for a gasser ?

not really. 13 will mop the floor with it.
Class rules require a 23* head? That would be the only feasible reason I could think of.
@@dougcrosby6994 There are lots of guys building 800+ hp 23 degree engines. It's alive and well.

How many cc's is that head
Around 275ish
It doesn't hit a choke and go turbulent.
