Posting this because doing it everyday for the last 13 years, I never thought it was possible. But it's happened.

400cfm 23 degree SBC. Raised Runner All-Pro..

It's far from bracket stuff, it's expensive, it needs weld, but it will make some steam.

Few pics of the master port.

Those the AP227 castings? Start with them bare or did they have some work already? Is that spark plug all the way in? What plug? I ask because mine are recessed, the chamber is not open enough to get the plug in there like yours. I was told that casting is meant to be used on a 4.185 or larger bore, I am only 4.155 and did not have the chamber opened up, wanted to keep the compression. Heck, it was a 4.125 bore for years!

RR245 casting. I put the plug where I wanted it and will have the chamber welded below it before they are CNC'd..

So does anyone make a raised runner tunnel ram manifold that will fit these heads or will it require a fabricated intake?
Considering these but still want to run my Enderle hat injection.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

That casting may be very similar to mine, and T&D has the correct shaft system for them off the shelf, I use the AP227 casting. It is a raised runner design and spread port exhaust. Call Bob at All Pro and check with him.

I used the same Brodix intake I had on my Brodix 11X heads which were "normal", not raised runner. Had material welded to the top of the intake runners to match the heads. China rails have a spacer on them. I buy a stock Felpro intake gasket and use a Dremel to open the height up to where I need it.

I will find out here soon. I found a DANA 44 for it and went from 3.23 to 3.92 gears. Also have a complete 3" with a Spintek muffler I'm putting on it, then chassis dyno. Just been busy. I did buy another one however! Driver.

Why do you need to stay with 23 degree on alcohol?

Never tried 18 degree on a SBC with alcohol but 18 and 12 degree BBC I have and I don’t want that headache ever again. I’d rather just stay 23 degree so I know there’s no issues

I've ran a 15 degree SBC on alcohol for 10 years with no problems. That's why I asked.

I think that used to be pretty popular with sprint cars too.
