1000 would be easy with a little more intake work and can.

Didn't Bruce M make a 1030 hp or so?

I have a set in my cylinder head chart. But wanted to make sure that those numbers were really correct. So I check with Larry Meaux and got which more than just a yes.

You have a high end set of Barton High Ports.
You have a high end set of Barton Pro Ports.
You have a set of high end set of Tiger 2s.
I bet you have enough money in those 3 sets to buy a 3 bed, 2 bath 2000sq foot home in Arkansas. And you are going to "bracket race" your Tiger 2 engine ?
My post that Super Chiefs are soft is valid. So do what you do with the new "circle" and rip away.

You have no clue, you assume a ***** load of stuff!! But correcting your assumptions is a complete waste of time so you may continue being an idiot.
I would like to know how starting this thread im controlling who can post. That's a new one

I would like to know how starting this thread im controlling who can post. That's a new one

I'm willing to listen to his firsthand info about the sc heads....
So Dcar, tell us about your sc"s and the issues you had with softness?
Seems others are making laps with a blower motor without issue.... so please, enlighten us with your firsthand info...

Aluminum is “aged” through either thermal induction or chemical treatment to induce hardening. Any heat treating company familiar with aluminum has the required furnaces to accomplish the task. Let’s look at 356T3 for instance. 356 is the alloy number; T3 indicates the aluminum was artificially “aged” to the T3 standard. ALL aluminum is T1 before “aging”. The normal heating/cooling cycles are what age aluminum. A wise builder will anneal any aluminum component BEFORE welding or machining it to insure uniform “aging” and hardness.

Lil Jack do you remember many details of that build? Cam size, valve sizes used, anybidea if bes digitized the ports?

[opeliac]

OK, can we get a final answer on the heads?

Does anyone have a CNC program for them?

Can they handle 2000+boosted HP?

I’m a huge fan of the KRE HP head.

That being said, valve height and angle of the SC head by design has the potential to make more power if the port work is developed properly. I doubt a CNC program is available since at the time these heads were produced, CNC was just starting to become mainstream.

With the cost of duplication today, it may be a good option if someone has a great head to copy as the cost to develop from scratch will not pay the return.

Calvin,what were Ric and Dave Johnson running with the first gen heads in N/SS at 7 lb per CI,I seem to remember they were running high 8s?Tom

Dave ran bottom nines high eights with
Wenzler II heads.... Hopefully Calvin remembers what Rick ran.

[J.C.you]

Stan, ...Yeh, my old SCs. Still have them. Did some more work to them after the last time on the bench at Meauxs. Plan on running them this spring.

Rick has been running the Wenzler 2 heads also. Hoping he get the new bullet out this year with the Warp 6’s. Should run pretty good with all of his car changes.

I talked to him at Norwalk and he filled me in on his build. It will definitely Bad Azz and I encouraged him to git'r done. None of us are getting any younger.

Hi JC, did you ever get to dyno those heads or run them down the track? ..... They seem like they have a bunch of potential.

[catalina_dream]

I believe that Rick's best was 8.80 @ 153

The OP might want to call Heads Up Cylinder Heads in Dayton OH. It's been many years ago but Dave Layer, (owner RIP), had a program for them because I remember seeing a head in the Haas Machining Center. Randy Brewer is the new owner of the business and may have the old programs. Worth a phone call: 937-431-5555.
