    Good to see this thread, not a lot in it, but worth keeping alive.

    Working on my brothers 79 Caddy with a 507 from MTS. Told its 8.3:1 compression build. Big lumpy cam. Figure my brother

    intended to supercharge it.

    Looking to see if off the shelf turbo cams available, and good blow through carb setup.

    MTS said motor is good for 380HP / 500TQ as is.

    Being E85 is around here a lot, that can be a turbo + low compression's best friend. And E85 carbs are out there now.

    I figure if this is 8.3:1 , I could run a pretty good sized turbo with a good exhaust A/R to give it a good street/track response.

    Would need to figure out fuel supply upgrades (remove mechanical pump?) and few other odds and ends as new to the 500 world...

    In my sig, is my turbo 3800 v6 (200k mile stock bottom end, turbo cam, very mild head work) on E85. Runs like a champ. Ditched the old stock

    M90 blower in favor of the turbo. Couldn't be happier with the results.

    Check out this turbo. Borg Warner S400-75:

    I've run a BW S200 on my Ford 2.3 for a few years now and it's an absolute beast. Or at least it was, until the #2 rod exited stage left through a baseball sized hole in the engine block. :worried: I love BW turbos. :yes:

    11855BF1-58F8-4A50-AB15-51255CC4A51C.png Here are the mirror image turbo units.... These could make some boost on a 500 Caddy?
