Last time I looked through a Mopar Performance catalog, there were lots more
mods available for pre magnum v6 motors than for magnums. Granted, my catalog
is now 3 years old, but I see a lot of parts for pre-magnum motors. Here's
what it lists.
Stage I Engine Package A
Hydraulic cam P4452806
Valve spring P4286813
4-BBL carb P4349229
Intake P4452114
Ignition package P4529402
Chrome valve covers P4452042
Estimated 30-40 hp gain over stock (1991 and earlier)
Stage II Engine Package B
Same a Package A except for the following items:
Hydraulic cam P4452808
Valve seal package P4452050
Centerline camshaft key package P4286500
Roller chain and sprockets P5429267
Low restriction exhaust
Estimated 15-25 hp gain over Stage I
Stage III Engine Package C
Same a Package A and B except for the following items:
HP cam P4452810
Valve springs P4120249
Chrome moly Retainers P4452033
Headers
Header gaskets P4452061
Backcut valves P4452051-052
Estimated 20-30 hp gain over Stage II
Stage IV Engine Package D
Same a Package A, B and C except for the following items:
HP cam P4452814
HD rocker arms P3690710-711
Ported Head P4452747
9.0:1 Pistons P4529419
V6 electronic distributor P4529401
Estimated 30-40 hp gain over Stage III
Building a stage IV would nearly double the HP of the motor. Mopar
Performance also had a 3.9 Commando crate motor that was 160+ hp. I would
still rather do a 360. Point is there are a few pre-magnum mods out there

Good luck finding mods for your pre-magnum V6. I bought an '89 new
and have had absolutely no luck finding any significant mods that were
cheap enough to install that would give any respectable gains. I've
got 150,000 plus miles on mine now. It has always been a DOG in the
performance bracket, but gets very good fuel economy and does
everything I expect it to except run down the Interstate at todays
legal speed limit and have anything left. It will do 75 in OD - will
eventually do 105 in 3rd (Automatic OD) and takes a mile to get to
the legal limit even floored from a dead stop. As reliable as anything
I've ever owned, but performance and pre-magnum V6 don't belong in the
same sentence.
I just last week purchased a '95 V8 CC loaded. Now thats a whole
'nuther' story. It will run.
Good luck.
