    your gonna have your work cut out for you..its not a drop in situation here.
    you will have to address the motor mount situation. i would just go with a front motor plate and by pass this altogether,,,another problem with these cars is the clearance in the sub-frame cradle area...Causing header and oil pan clearance problems....while you have the small block or engine you now have in the car, you can address this situation in 1 of 2 ways..you can go back with tublar sub-frame or you can have the cradle cut and box plated to give you the extra clearance you will need.
    IF YOU ARE NOT handy with a Plasma cutter with Good welding skills, you may run into a cost effective decision...#1- hire someone to cut /box/plate the cradle, with front motor plate #2 buy the factory bolt in tublar kit.

    the tub kit would also saye you some serious weight...


    unless someone has taken a 1983 camaro and placed a bIG block in it ..you are most likley gonna have to trial and error this one on your own.

    by the way they do make a hooker header for this year body style car, small and big block.

    Good luck.

    Anything will fit anywhere, if you have a big enough shoehorn (i.e. torch and welder). Trust me, I put a 460intercepter out of a CrownVicky TN state patrol car into a 1974 GREMLIN X! Everything had to be hand fabricated.
    I don't want to arrive at the pearly gates in perfect shape, rather I want to come sliding in, all burnt up, screaming "WHAT A RIDE"!

    don't quote me on this Mike but i think your model is a little more forgiving when swaping a big block from small block..close to the same with a 1st gen camaro....keep in mind also when you take factory small block car and place a big block in the car you normally have to change the front springs to a stiffer "big block" spring or your front end will sag..

    Good luck

    On the 3rd gen, I think that you also must delete the AC box on the firewall. Some years ago, I knew some guys that had the BB in a 84 Camaro and they had gotten parts from Ed Quay for the installation and they ran the motor plate.

    As Brian said, a lot easier to put big blocks in 2nd gen camaros...mostly a bolt in.. I seem to remember early 701/2, maybe 71 or 72 you could order the camaro ss with a big block, 402 I think it was.
    I put a 427 in a 75 camaro years ago, motor mounts were the only thing you need to have the right ones. Front end went down a bit, but we did not change the springs. They were the original small block springs.
    And of course you can buy headers for these things off the shelf.
    The biggest problem you will have is that with a high rise intake, the carb will not fit under the hood, so a hood scoop will be needed.

    As far as the 3rd gen camaros, well these days you can put any motor in anything if you want to work at it a bit... I cannot seem to remember anyone around here that has done it, but I am sure there are many bigblocks hiding in 3rd gen camaros out there.
