if you are going to go the V8 route, keep in mind that you'll need to
upgrade the transmission. on a 360, you'll have to install a 46RE, and all
the required parts. while you're at it, make sure you install something
stout, or you might be pulling it to rebuild.
if you are just going to use this to putz around and have fun, you might
just want to stick to the V6. however, the V8 is tempting.

Subject: DML: 3.9'er Needs performance advice
Hi folks,
I've thought hard about it, and have decided NOT to buy a new car, mostly
for
long term financial reasons. long post.....
ANYWAYS,
I've been discussing my options with my 1999 3.9L Auto V6 R.C., and a close
friend of mine who has done some engine rebuilds as a hobby has thrown a lot
of
ideas at me. I'd really like to stay naturally aspirated.
1. Rebuild the V6 either inside the truck or grab a junked one and build it
from scratch. this would include a set of original heads ported/polished,
new
cam, the standard bolt ons (elec fan, headers, new exhaust, modded intake
manifold, new injectors, throttle body, intake) and a new valvetrain.
My calculations working on the engine inside the truck would be 2700-3200$
(rebuilding an old engine $3200+). According to him with this option, "I'm
wont
be very happy". I'm guessing its going to be 250-280 h.p. at the flywheel
going
this route? And 300+hp just isnt possible without a terrible idle? (or
forced
induction?)
2. 360 short block kit, possibly from summitracing. I think those are MPI
360's, and I've read on the list in the past the trouble with getting an MPI
setup to work. Im guessing this would be more money: new front springs
(shocks?), harness, computer, heads, intake manifold, oil pump, oil pan,
water
pump, ect.ect. I calculated around 4000$ for this one.
How much trouble would it be to make the engine and computer play nice?
assuming i could get a computer and harness?
3. Same as #2, but used the one set up for carbbed applications.
I know some folks have done this in the past, and was hoping for some of
that
20/20 hindsight :) As for what I'm looking for, I'd really like for this to
be
worthwhile, I dont really have a target h.p. or E/T. I really would like to
stay below $4000 whichever route i go. And yes, i know the tranny is gonna
need
work :)
