Question 1990 318 engine

I found a dodge engine and tranny for a good price out of a 1-ton van. i need an engine for my '47 plymouth and was thinking of using the 318. What i would like to know is how hard would it be to take off all the techy sensors and crap from the '90 engine and convert it to carburetor? I would like to take off the emissions stuff and catalytics. Also, with the 1-ton tranny would it be hard to find a console shift that would work with the linkage? and lastly should i use an older wiring harness?

Any help would be appreciated.

Thanks,

JB

Cool

Converting it to carb is fine, but most of those dodge fi motors had an electronic overdrive, necessitating using the ecm. If the tranny is all mechanical, no problemo-look for wires from tranny-if there are any, you'll need to deal with it.

Which motor is this - is it a magnum or an A engine - there is a difference in heads and intake and the switch over happened around this time, so make sure you get the right thing. Converting the motor to a carb is no problem. Multiple suppliers carry cams, intakes, carbs and distributors for the motor. Many of the old A engine parts work on the newer magnum blocks. Just make sure you get the right intake - the bolt angle on the magnum is different from the older A engines.

As for the tranny, I have a 5.9 in my 2001 Dakota with the electronic tranny. Mine had an electronic valve body that I replace with a hydraulic one. I still have the lock up converter and OD, and run them off of one push button on the shifter. Around town, I run it like a 3 speed. On the highway, I shift it into OD and it locks the converter and puts it into OD. I have seen people put a series of pressure switches to do it more eloquently, but mine has worked like this for around 5 years. The folks at SMR transmissions in Canada helped me get everything working, and rebuilt my overdrive to take the extra torque of my new motor - this is a weak link on the Mopar tranny. Based on your year, I think yours should be a little easier as I don't believe they had the electronic valve body in 1990.

The 1990 318 is still a LA engine and it is easy to covert to carburetor.
You will need a distributor, intake manifold, carb and a electric fuelpump.
I have done this on my 1990 360 that is sitting in 1948 Dodge.
The transmission is in my case a TF-518 = TF-727 + overdrive. The overdrive is easy operatded with a simple switch connected to the transmission harness.
There was also the TF-500 available at this time = TF-904 + overdrive + Lockup
I'm not sure if the TF-500 is as easy as the 518 to operate.

I hope both of you will get Mopar power in your Mopars.
