From my own experience with an '88 F150 with the 5-speed & 300 cid
engine, I would caution you when looking for performance mods, to
research aftermarket exhaust systems carefully. I replaced the stock
system on mine with a Flowmaster "Big Block" muffler and dual outlet
tailpipes, and felt that both performance and gas milage suffered
somewhat. Obviously gas milage is measureable - there certainly was no
improvement, and may have been a decrease. By a performance decrease, I
mean in acceleration "snap", and there was no noticeable improvement in
performance when towing a trailer, either.

In spite of what I've read in various posts here that you can't have TOO
much flow through the exhaust system, my conversations with the
technical support depts. at Flowmaster as well as Bassani dispute that
contention. I don't know the answer; my experience is my only reference.

Regarding other mods, since I had to rebuild the engine at 100K due to a
bad rod bearing (evidently a common problem in '88), I did look for
possible performance mods that could be done, but found very few readily
available (i.e. easy) mods for the injected engine, beyond headers. The
major problem is that the engine control system in '88 is Speed Density,
not Mass Air. Don't know if that was changed by '90 or not, but I'd be
suprised if it was. While it is possible to "cam up" the engine, modify
the head, upsize the injectors, throttle body, etc., you have a hard
time getting the EEC to deal with the changes, from what I've read.
Seems like the most logical mod for you would be rear gears.

From my experience, the more flow the better, PROVIDED all you're interested
in is constant high speed, racing or WOT performance. Reduced back pressure
tends to increase horsepower - but mostly at high rpm's. So, in a racing
application where you're maxing out your engine all the time, a tuned, wide
open, unmuffled exhaust system is usually best.

For more varied everyday street/strip applications, however, a little back
pressure can be a good thing. I remember a few years ago I was playing
around with my Harley FXLR's exhaust system (as us greasy old bikers are
prone to do). The stock system was, of course, too quiet and really
bottled up the engine's potential power. However, it produced great low end
torque. So, naturally, I went to the extreme and installed drag pipes
(open, no mufflers). Well, what resulted was a little too loud (even for
me) but gave great high end hp at the expense of much reduced low speed
torque. So, to find a happy medium, I cut off a length of the drag pipes
and installed a pair of high performance, low restriction "slip-on"
mufflers. This did the trick. Great sound and better than stock low end
torque and high end horsepower.

I guess this is why, a few years ago before there were so many aftermarket
exhaust choices, you would see lakes pipes and exhaust cutouts on all the
hotrods. You could open it up for racing and cap it off for the street.
Now, of course, the aftermarket possibilities to accomplish an acceptable
compromise are almost endless.

Mea Culpa.. never crossed my mind as I've never had the chance to work
on or drive one. :-( Heck my parents hadn't even MET in '53 and I came
along in '62.

I did say it was by no means a complete list.. Straight 8s deserve
mention as well, but I just popped off the first few engines that came
to mind. One engine I'd *like* to see meet an early demise would be the
asininely engineered Quad 4 GM power plant.

Been some talk on some of the lists about car shows, so .......

For any & all interested, the New Hope Pennsylvania 43'rd annual auto
show is this Saturday & Sunday.

It will be at the New Hope-Solebury High School on RT.202 in Solebury
Pennsylvania.

I'm going to have to e-mail or call him myself for directions, as I've
never been to this location for the show. It used to *actually* be more
*in* the town of New Hope itself.

I'll probably be going Saturday.
