Blew the 5.2, building a 5.9
So I blew the 5.2 up at a mud bog last weekend. It was having that stutter problem most of the day but she still ripped up the mud. What I want to know is, will I need a 5.9 PCM if I put the 5.9 into the truck? Stock it came with the 5.2.
will I need to change anything else with the new motor?
thank you

Keep in mind, the 318 and 360 (I'm old and not metric) are balanced differently. One is internally balanced and the other externally.

98, what would I need todo different for the 360 then? I see the PCM isn’t needed but I’ll probably swap that anyway because it might’ve been a problem before with the 318

On that year, the balance weights for the 360 were on the flexplate. Just use the correct flexplate, and you are all set.
Also, being you use your truck in the mud...... you REALLY want the correct programming for the larger motor. (as you probably spend a fair bit of time in open loop, and running lean while under load is just bad. Tends to blow holes in pistons. ) So, PCM flashed to the correct VIN, and the correct programming for the engine/trans.

do I NEED to reflash this PCM or can I just swap in a pcm off of a 5.9 truck?
