hello surfing around and found this site and joined.

I have two vehicles a 58 mga with the 3.9 fuel injected v6 out of a late model firebird running the compllete fuel injection system.

Also have a 47 fargo 1/2 ton (same as a 47 dodge) it has the origonal engine in it a 251 cube flathead 6 cyl.

i made up all new intake and exhaust manifolds for it and used the complete throttle body fuel injection system from a 92 chevy pickup the 4.4 liter.

running the stock computer and all the sensors. it was easy and i dont have to worry about tuning fuel and timing.

it is like the rotissirie commercial on tv, just set it and forget it.

the beauty of this set up it can be bought at most junk yards for 100 to 200 dollars. and the parts are readsily available at any parts store.

Here is how i did it, bought the throttle body harness all sensors and computer at a junk yard for 100 bucks
had a buddy machine an adaptor to convert the carb mount to the throttle body ( 2bbl in to one)

machined the chevy diistributor to fit the chrysler

installed a different fuel pump, ran a return line for the fuel to the tank and mounted all the sensors.

cranked it up ( not even two turns of the flywheel and it burst in to life) the engine ran about 2500 rpms for 15 seconds then the computer started reading all the sensors and it settle down to 725 rpm.

by the way i am a 58 year old guy, and it was not hard to learn, and it is easier than changing jets, and because there is no fuel wash on the cyl walls, i now have the best of two worlds, the beauty of an old flathead and modern efi and elect ignition so i now have a motor that will easily run 200,000 miles or better between rebuilds.

If i am in the mountains the computer knows it and adjust the fuel and spark as necessary.

in fact i was so pleased with the out come of the project that i ripped off the old restritive intake and exhaust. and designed my own.

went backt toe the machinist and had him make a new intale- exhaust flange out ot 3/8 steel, and had him drill - machine it with 1/2 " holes for the intake and exhaust tubes.
next i mounted it to the engine, and ran over to the local exhaust shop.

I had them bend me a set of 90 degree bends and then trial fitted them to the flange, and when i had it set i just welded it up. then i took it back to the muffler shop and had them make a collector for it.

now it looks like a tunnel ram intake and is awsome in looks and performance. the exhaust and the intake are equal length.

if any one wants photos or info i will provide it.

also the reason i used the setup from a 1/2 ton chevy pickup, is to save money, that vehicle down not have an anti theft built in to the computer.

hope this is of help,

John
