>>Here is three things you can do without gittin "inside". First,

Late models came with a weird factory header, almost like a tri-Y except
with the obvious difference. Are these adaptable to earlier trucks? Are
they worth retaining on late model trucks?

turbo's, the

Has anyone tried the Edelbrock Performer RPM mufflers? They look like
Turbos, but on the inside they're more like glasspacks. They are also
stainless, which is good because if I have to do exhaust work I only want
to have to do it once.

a 350

put a

I assume the chip is necessary to convince a speed density truck that it
is now SUPPOSED to be non-stock...

Is there enough clearance to do this? I'd be extremely leery about
changing the valvetrain geometry without doing the "clay on the piston"
test first, though this does sound like a fairly mild upgrade. Where
does one find this sort of rockers for the Big Six?

> I guess I don't understand your references to "true" gauge and "idiot
light" gauge
>... I've heard the new oil pressure gauges referred to as idiot gauges

My understanding is that the late model gauges are not linear. They are
built this way so that they stay in the "middle" of the gauge over a wider
range of operating conditions. That way the dealers get fewer complaints
over conditions that are not really serious problems. The downside is, for
people like us who really want to know what's going on in the engine, we
get less useful information. So even though you may have gauges on your
late model really don't know much more than what you learned
from the old idiot lites.

>boots I kinda swore off (and AT!) mechanical gauges. :-)

I hate it when that happens!
