Scotty Brown CNC alum 350 head porting

It sounds like Scotty Brown is beginning to offer a CNC porting program for the 350 alum heads! $1450. I may send my spare heads down there.

 

What kind of flow did the program produce?

 

I’m not sure, I texted him to find out.

 

From scotty= game changer!!

 

It'll be interesting if you do to see the difference between his flow numbers & your hand ported set.

 

Thats great news for ppl. I love my te2 he did. We actually we lucky enough to do a same day back to back comparison on my cnc heads and amp mikes best hand ported set of heads. The numbers were actually very very similar. My heads were normally just a few cfm higher....like 3-5.........but only a very few select spot did I go more than that, and couple spots I was couple under. Mike was very impressed because he said he had so many hrs in these heads that there was no way anyone could ever pay that much labor to get them.

I do know some ppl have gone over 400 on the te2 heads....mine maxed out at 383, but, for 97+% of the ppl the cnc program will be more than they ever need.

I'm sure if scotty has a cnc program it will flow and better than that actually run well. Great flow numbers are 1 thing, actually running well in real life is another

 

The great part is the repeatability. Now anyone can simply buy their TA heads through scotty already ported and bolt on HP.

 

The best part is every port is exact and balanced. One port doesn't outflow any others.
Did he have a cost on a head pkge?

 

Maybe Scotty should set up to do the full machining and then ppl could jist but the raw castings from TA. Yes, easier said than done I realize.

 

$4100 out the door if they supply the head castings but we have no idea how many years it will take TA to sell any more castings. So if you supply the bare heads its about $2450 for the parts, porting and valvejob. Keep in mind they used a 4" bore on the flow tests. My tests are with a 3.830" bore:

Isn't that 2nd sheet yours and the range size = 4"?

 

The second sheet is mine but no I am not sure what "range means" but I specifically remember him setting up a 3.830 bore as that is my bore size. Why Scotty is testing with a huge bore I am not sure, but that would drastically change the flow results. I wouldn't go past 60 thou (3.860) on a 350 personally, I prefer 30 over allowing it to be bored over once or twice if needed later on.

 

3.800 bore is not a common standard size, so most just use the closest they have. Chebby 4"
Not many hotrod 318 Chryslers....or 350 Buicks it seems. IDK how much of a difference it makes using the 4" cyl adapter.

 

He emailed me more info. Note the bore size and valve sizes.

 

That is very reasonable,but this also comes from a guy that usually spends about $10k on heads.
Now,how about the availability of the heads?

 

I have perfect availability, I purchased two sets right away. For everyone else it doesn't look too positive, TA can’t seem to give a timeline on when they can find someone qualified to machine thier heads. It’s a shame as they have pallets full of heads to be machined.

 

Mike Sr or Jr better start loading & running the program themselves.

Can Scotty finish machine them at his facility while he's porting them anyway?
There has to be a program written already.

 

I work In robotics and I do set up robots to load and unload CNCs and mills for a living..
TA reach out to me if you need help , I can point you in the right direction

 

Any chance they can be purchased as a raw head?

 

I think they'd sell them that way (I may have even asked). I don't need them right now & can't really afford them anyway and was thinking about just buying a pair of raw castings to have just in case they never made another run but Tim assured me they'd "always have them."
