It is taking longer than I wanted, but with help from Chris (440pursuit) it is closer now to being done.

Looking good! What’s the combo?

512 LD, with heavily modified Stage VI heads, 630ish cam, Modified Indy 440 intake, built 727 w/ brake, 3800-4k stall, back halved 4 link car, full cage, 4.56 33x19.5's

What's your goal for this build

go out and have fun. Should run low 10's when all is right

Lookin Good

nice

Tex

LIKE!!!!

You know all the epoxy in those runners means your fuel needs to be absolutely alcohol-free, right?

I wonder who added the raised ridges in the port floors... they weren't there when those heads were done originally.

Nice Paint!

Looks like it will be a fun car at the track!

I assume the intake runners match the ridges in the port floors. Can anyone school me on this theory? I assume it has to do with splitting the intake charge to minimize the obstruction of the valve stem and guide (?). I’ve never seen this before.

I think you got a great deal on that car, looks really good.

I'm with you on this one is this the new modification being done to these heads now?

One of you should post these questions with that picture on SpeedTalk.com and see what you get for answers.

What's it going to weigh? With 500+ cubes, etc., it should be in the 9s, unless is deceptively heavy or the combination of gearing / converter / whatever isn't a good match.

The heads were done because of NHRA rules I believe. The ports have been moved and raised. This is a former members engine. It was designed to run 9's. The car is all steel, so I suspect it will be close to 3200 w/ driver and gas. It could probably run 9's on "pump gas". I'm just going to take it easy....

I guess I should check out SpeedTalk.com. Thanks for the tip, Brad.

If it is in fact to shape the charge past the guide boss & valve stem, it seems this mod would be more effective on the port roof than the floor. If the charge follows the port into the bowl, wouldn’t charge following the upper half of the port cross the guide boss & stem, while the floor charge would fall directly across the valve face (???).

It's not.

Quick history lesson:
1. The castings were mine, originally... had an uncommon feature of CNC chambers, although the ports were as cast.

2. Another member bought them and provided them to the group from Moparts that entered the Engine Masters competition... 2003, IIRC. I believe four different people had their hands on those heads to complete the work. The only one who still posts here on any regular basis is Dwayne Porter.

3. Jim Hanrahan "440Jim" bought them and ran them on his A-body bracket car before going "big" with a new engine and switching to E85 fuel. Any alcohol in the fuel will turn all that epoxy to sh!t.

4. I knew Chris bought them, but didn't know if he ever used them.

The last pictures I'd seen of them did not show the additional floor "wing". I don't know if those were used on all of the ports, or only certain ports, or... ? They aren't part of the original epoxy fill to raise the ports.

Brad I thohght they looked familiar but could not see a lot of that port. You can clearly see the "wings" are made from a different epoxy as well. Not sure its the "hot ticket". Be interesting to see how it runs..In the end the OP has the right idea. Build it and have fun with it...
