1992 Dodge Dakota 5.2 Magnum advice

You have any pics of the truck? I have had three R/T trucks over the years but my 95 is by far my favorite. With what it sounds like you want to do the OBD1 can be made to work. Mine is pushed to the ragged edge of what it can manage but it does it fine. I will be going to aftermarket EFI setup in the future because it will be a must with the next motor but.....I am running a mild 5.9, (mild cam, Mopar perf. M1, 24lbs injectors, Gibson shorties, and fastman throttle body, this is run on a Mopar performance 5.2 module. I went from the stock 3.21 to a 3.91 and hated it. Granted my truck is a five speed and first in the NV3500 is to deep for the 3.91. My truck is actually faster with the taller gear for this reason. You shouldn't have that problem. Use the gear you ordered, buy some decent heads for the 5.9, stay mild with the camshaft, and buy the MP module. The truck will be plenty fast and great to drive.
