I was always going to take an old head and put it in the chop saw and cut it in half through the intake port, just to see if the water jacket is close. If not, why couldn't you drill holes in the head UNDER the valve cover for the injectors? If you drilled them at an angle, you could have the injector shoot right down on the valve. Some sort of fuel rail could be make to supply the injectors. Imagine the dumfounded looks when you popped the hood and the only thing on the intake manifold was a throttle butterfly and a MAF sensor wink

I just got back from a technical school on John Deere High Pressure Common Rail fuel systems. This system is absolutely AMAZING, both in diagnostic abilities and horsepower output. This will require a lot of thought to adapt this technology to a Stovebolt, but I think it could be done.

Racecarl,,,,,you have my ears perked!!!!
This sounds interesting!

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

This photo is looking at the center intake ports on the 292 I just got. See the two small dimples ontop of the port on each side?Looks like you could drill down for an injector. The two end ports are about the same. If the injector nozzle is 3/8 of an inch or so it could work [img][/img]

I've got a couple of link's you might want to look at.

Hopefully, with all of those maybe you can come up with something. The dyi-efi site can be a little flakey to get to, but it is the most technical. In other words, written for/by engineers, which is what you want.

Uhhhhh . . . Vaughn, I think there is something funky about the Motorhood link. Other than that one, these are among the best I have seen.

Peggy took care of it, Ken -- Thanks for the vigilance. It was fun cruising to the Turbo Buick site -- When those Grand Nationals came out, I wanted one so bad. A buddy of mine bought one and took me cruising the night he got it. Then he parked in downtown in DC and it was gone. He got it back a month later -- well, just the frame and the body... Had less than a 1,000 miles on it, too.

Take a look at the picture Tony posted.

In the center of the intake port is part of the head casting that the head bolt goes through. It is basically round, it does not separate the two intake valves behind it. A trick to improve intake flow a great deal, is to mill the casting out of the port. A stud is used instead of the original bolt, with the stud protruding into the port only by enough to install a nut. The flow over the nut does not disturb intake flow nearly as much as the casting did. The hole left above the port where the bolt went through is closed off using a plug.

This should improve the power of an injected engine as well.

Tony, I may try to get pics of, here we have 250 with multiport efi. But with a whole different head. Separeted runners on all cilinders, they do not merge after the bolt.
Greybeard, this procedure helps in high rpm, hurts a lot the low end grunt. And we can have for sure that to keep it going must run a li'l rich in lower rpms, so fuel consuption suffers a lot.
For a long time the tunners here used to do it, remove the center of the port, but it's results are not clear, some like, some dislike, but listening to the results of a 12 port wayne on a stovebolt, I'd say that I'd rather have a full divider in a head port than running an engine with a common runner for 2 cilinders.
Just my 0.02.

Wow! you guys are too technical for me! frown Back until 99 models in truck plant here, we made Mexican sixes and trucks that were mostly the same as the old 250's. They had a fuel injection body in place of carb on them the last few years. don't know if you can go to Chevy dealer and get #'s of parts or not. Maybe the last poster is talking about this engine as it was made in Brazil I believe. It's just a stock set-up, not racer, but may be better than a carbed one. wink
