    I thought you guys might want to see whats been sucking my wallet dry for the
    last couple years. I just ordered a Magnaflow CAT back for it, good thing too, it
    is WAY restricted over 2500 rpm with the stock setup.

    Thanks. Funny though, I didnt actually drive it. Its the wifes car so she was
    behind the wheel. I was sitting in the rear seat passenger side with the data
    scanner watching everything. It passed each test, converter unlocks when it
    sees a brake tap, locks at around 49 mph, temp stays around 208 degrees, it
    goes into gear softly (no surge/clunk). IROC steering box is doing its job and
    the fuel gauge works (though isnt accurate below 3 gallons).

    It was amazing how it dogged out attempting to go into passing gear. For a
    300 hp engine it was terrible. GM really put together a restrictive exhaust in
    1978 and all along I thought it was the 305! I think a stock 305 could benefit
    from a modern CAT and an aftermarket CAT back.

    She DID say the ride was kind of harsh - this was the first drive with the PTFB
    upper control arms. Not sure if they are going to stay, I might be forced to go
    with Hotchkis and sell these on the forum. We shall see.

    With stiffer suspension components it will seem harsher ( see my sig), but I would rather have one that will respond to my inputs than the other way around.

    As far as your passing gear, it would depend on what speed you are at. My Camaro and my truck for that matter, if you are going around 25-35 mph and nail it, it will take off like a scalded dog. Around 40 and above, it will kick down and take off, but not with the surge of torque you expect.
    However, I have not messed with the transmission parameters and I'm sure yours will be the same way.

    Another point to ponder, try not letting the tank get less than 1/4 full, it is hard on the pump.

    The engine is from a 94 Firebird, and the speedo was off, so some of it might
    be the pressures in the trans being lower than needed. It didnt put your head
    back the way our 1995 Z28 or 1993 Z28 did. Both those cars had 2.73 ratios
    in the rear ends. The '78 Camaro we "guess" has a 3.08. Speedo was reading
    lower than we were going (this is based on feel vs data reader).

    The single exhaust factory pipe looks 2.5 inch. Bends over the axle have the
    awful crush and bend you would expect from a corner gas station.

    If your camaro originally had a 305 2 bbl, more than likely it will have the 2.41 gears, there is a two letter code on the passenger side drive axle towards the front that will tell you the gears that are in it. if you have the code I can tell you what it originally came with.

    Seeing it move again was a big relief, there was a few times in the last year I
    started to think I bit off more than I could chew. I tried not to let the wife in
    on that as much as possible.;)

    Number in the forward edge of the pass side axle tube : 2 PJ G8 1002
