I would say you came to a great group of knowledgeable
people that focus on all vettes..

g'day

Some here would say yours is not an old car.

Your best bet is to go to www.corvetteforum.com and view the C3
forum....unbelievable amounts of information there and you can ask questions
without worry.

With few exceptions, most on here talk when talking needs to be done. Hence,
you see a low number of posts.

On places like Corvette Forum, many talk to raise their post counts, so you
think that there is a lot being said but you really are seeing lots of
unnecessary posts.

If you want help, you have to ask here. There isn't much to search for.  So
if you need to know how to remove the rear end or what distributor works the
best, you have to ask. On CF, you can search and find 500 posts on the
subject, most of which are the same or TTT or "I agree" or other such waste
of bandwidth.

If you had asked for the AC recharge, ignition and exhaust system upgrades,
you would have gotten answers.

AC recharge. The R12 is the coldest, hands down. It depends on if you can
get someone local to charge it with R12. Otherwise, you have to convert. You
can get the kits, but really, in a 30 year old system, you need to replace
seals and hoses to get the R134 to work its best, which is still less than
the R12 will in the original R12 system.

Ignition. I'm a firm believer in the original GM HEI. You need to find a
local shop with a distributor machine and set it up for your best curve. I
suggest you go over to the NCRS technical discussion group (www.ncrs.org)
and request Duke's remapping scheme so you can get the best out of it for
your car on today's gas.

MSD is a great system for racing. It makes a poor system perform when
conditions are their worst.  However, on the street, if you simply make sure
your system is in good condition (new plugs, wires, etc.), then a stock
ignition will perform well enough. Usually the advances of the MSD is over a
points system. The HEI is already throwing such a hotter spark than the
points, you don't have that issue.

Accel and other drag-inspired parts. They are great on the drag strip. I
prefer to drive more than 1/4 mile at a time.

Exhaust. The ram horn is about as good as you get. The 2-1/2 inch manifolds
with 2-1/2 inch pipes in true dual will open it up as much as you can
without headers, and headers will only have an advantage under mostly WOT
situations. Or you talking for the street or racing? If street, the stock
ram horn, maybe the 2-1/2 inch if you have several hundred burning a hole in
your pocket, and true dual exhaust will do all you really want.
