When you call Edelbrock up and give them the specifications of your
motor they will suggest the correct carbeurator for the application.

The ECM will no longer function when you remove the stock Quadrajet.
The ignition is computer controlled so you'll have to replace the
distributor with a mechanical vacuum advance unit. The new carb will
need to be set up carefully to avoid melting down the catalytic
converter. And it'll never be smog legal again. Some future owner
will decide to part it out and junk it because all the original
emission control parts are missing and all the wiring cut out.
You bring up a good point. I woder if you drop in an LS1,6,2,7 etc
(which qualify as low emmisions vehicles and probalbly burn cleaner with
the stock ECM than even a low mileage 86 IROC) would it be emmisons
legal? Or are the laws written so poorly that it would never qualify,
even if the engine emitted pure CO2 + water as exhaust gasses.
Most states follow CA law on this (CA has long been a leader in this
area) and there is a rule that must be followed to have it be smog legal
after an engine change. If you want to put an LS1 in, you can do so and
keep it smog legal as long as you put all of the stuff for the newer
engine (smog wise) into the car. The basic rule of thumb is, you must
have the smog equipment for the year of the body, or the year of the
engine, whichever is newer. If the replacement engine is one that was
offered in the vehicle for the year it was built, it's classed as a
replacement rather than a swap as long as all the emmisions equipment
that would have been there is in place. For the new engine, you can
often get a kit from a local junkyard that includes all the emmisions
and computer stuff (with the exception of the cat which must be bought
new according to federal law).
So, if you want to kick it up a notch, the best bet would probably be to
get either an upgrade kit from the junkyard, or get a doner car that has
been wrecked from behind to get all the engine related parts for your
car. If it's an auto, you would also need the auto trans to go with the
newer engine, as that is usually part of the emmisions certification.
Now, if you do this, in CA (and most other states as most follow CA
procedures) once you get it done you take it down and get it inspected
by the state smog agency and they replace the underhood smog sticker
with one specifying the standards the car must now meet. BTW, the hard
and fast rule is that the car must always meet at LEAST the same level
standard (for the body style) as was shipped. In other words, you can't
go to the truck type engine (pollution amounts are higher for them) but
you can go the other way. One deal would be that generally you could
not go to diesel from gas, but often you can go the other way. This of
course would not apply in your situation.
It would absolutely be legal. Anything same year or newer, swapped in
with all the original emissions related parts, is 49 state legal.
California would require approval by the air resources board but that
wouldn't be any problem. 330+ HP, better driveability, more reliable,
better gas mileage, lower emissions, and increased resale value.
Actually the 49 states all follow CA rules. It's actually quite simple,
you do the swap, get everything properly, and then make an appointment
at the referree station who will put a new sticker under the hood so you
can go get a regular smog test after that.
Not Virginia. Here the only requirement is that the replacement engine
is same year or newer with all emission related parts still attached.
No truck engines in cars, of course. Basically just the federal EPA
rules. The car must pass an exhaust gas test only in areas that
I put a '92 TPI engine in an '84 Firebird. No referee, no air
resourced board, no inspections, no approvals, no stickers. I feel
sorry for Californians.
That's basically what the CA requirements are. The only difference is
that in CA, you go to a state station the first time after the swap and
they replace your factory sticker (the one that says what emmision specs
the car meets, which is what the smog place checks it against) with one
that reflects the engine you put in. Nothing extaordinary really, just
a smog check at a special station so they can verify that you did it
correctly. As I understand it, that is done just because the state
doesn't trust the private smog stations. But basically what you
described is the CA process except for the referee station. We have
those in case you can't pass, and it costs more than a certain amount,
in which case after you show you have done at least that much work on it
to fix the problem, they give you a one year certificate so you can
operate it one more year while you fix the problem (the second year you
must either pass the test or junk the car). I seem to remember you had
to have spent 650 or more trying to fix it (parts cost I believe, but it
may be both parts and labor) and you can get by without passing for one
year. I actually had to go through this process once because I had
changed engines. It was relatively painless, even though I had not done
it completely correctly. The tech told me exactly what I needed to do,
and then set up another appt for the future and gave me a temp operating
sticker while I got the parts I needed and then came back and got the
inspection. Frankly it was cheaper than the normal process, since I
only had to pay for the cert, the inspection was free. From a money
standpoint, I would rather have to referee every time, as it would cost
me less in inspection fees. <grin>
I'm In Canada so some things don't apply. I just wanted to put a better carb
in, As my IROC is on year 20. But you guys sure brought up some good points.
Maybe I'll just do the carb kit ? & clean it up. I'd love to have it all
original but the guy who had it before me did some mods on her.
They are but when you hit the 20 mark. They cut some slack but not much to
say the least.
I'm glad they do but at times it sure draws back on what you would like to
do to your engine. LOL
All in all I think I'll just do the rebuild kit & se what happens or maybe
get my poor IROC on that show Overhauling LOL. Or win the Lotto ( I guess
I'm stuck with the rebuild.)
