    I am currently in the process of swapping a 73 Buick 455 into a 79 C3 Corvette, originally this started out with me buying a B.O.P. th350 transmission to tear into and look at, paid $175 for it and found out it was a fresh rebuid. And then you know.. i had to have a motor for the transmission. Then a car for the motor. I picked up a fair condition 455 from a 69 wildcat, turns out the motor is a 73 that was swapped into the wildcat. So i am doing a full rebuild of the motor to 10.5 to 1 compression.

    My "Performance" parts are listed below

    Speed pro Hypeeutectic pistons .30 over 23cc with valve notches.
    TA 288-94H Cam
    Stock rebuild on numbers matching heads.

    Rotating assembly currently being balanced waiting on the harmonic balancer ship date is the 10th of june

    Update on the build. Sunday afternoon me and a friend of mine slid up to the car with the welder and fabricated some mounts into the car. Set the carb and air cleaner on top and she just fits. I am thinking a filter top air cleaner might help with the airflow i will also be removing the insulation above the air cleaner so it does not fall down and get stuck in the filter.

    Cool! Considering that the Buick is about 75 lbs heavier than a SBC but 125 lbs lighter than a BBC, the car should really step out! Be interested to hear if the rear axle can stand up to the torque!

      With any luck and maybe some kind treatment it should.. but really who is going to treat it nice? I will keep pictures coming as progress comes along :)

    Hey Will,
    Love the swap into a Vette! Should be fun and fast when you get done.

    Did you ever get your sending unit situation straightened out?
    Cars with gauges used a different sending unit than dummy lights.
    I’m not sure of the part numbers or where to buy but if you post this question in th “Bench” you’ll get a lot of responses from many knowledgeable members.

    Good luck and make sure you post up some pictures
    and more info when you get the Vette done!!

      So I was able to find some brass fittings that allowed me to use Chevy Corvette sending units so everything should work pretty painlessly.
