Mike kZ Posted June 20, 2006 Share Posted June 20, 2006 Welcome! I think you're on your own with it. As far as I know nobody has done this swap. If you do it, take lots of pics and post here!! Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted June 20, 2006 Share Posted June 20, 2006 That will be a very cool swap I think. Do you know if you have to clearance the transmission tunnel for the th400? Regards, Justin Quote Link to comment Share on other sites More sharing options...

randy 77zt Posted June 21, 2006 Share Posted June 21, 2006 this is what the mig welder,chop saw and scrap box are for.plus blocks of wood .caddy is probably a very overlooked engine and there is nothing more satisfying then a boatload of torque.now for that rare 3.31 r200 ring & pinion.

But it's not like I know anything about caddies. The engine blocks are virtually the same, so the engine mounting position or location is the same.

Guest Mike Posted September 9, 2006 Share Posted September 9, 2006 Are you going for it? I'm considering the same swap. My SBC 350 may be toast... don't know yet. If so, the Caddy 500 may be the way I want to go. My SBC currently has the Scarab style mounting kit but I just bought a JTR kit. Any idea how much of this I can use? Am I starting from scratch?

grumpyvette Posted September 10, 2006 Share Posted September 10, 2006 -------------------------------------------------------------------------------- http://forums.hybridz.org/showthread.php?t=101463 you should read thru this thread first, and Id sure try to find a donor 1970-73 eldorado or similar car with with a 500 caddy if you can (preferably with rear drive) btw the 472 and 500 caddys have the same outside dimensions only the stroke, heads, and internals differ __________________ Quote Link to comment Share on other sites More sharing options...
Challenger Posted September 10, 2006 Share Posted September 10, 2006 Wouldnt a 500 caddy be way to heavy to put in a Z? I'm guessing your not going for autocross more a drag car? From what I know does a front heavy car make it understeer in the corners? Might not be a good autoX car but I bet itll fly in the quarter mile!! Good luck Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 10, 2006 Share Posted September 10, 2006 500 caddy Cadillac V8 472-500 625lb with aluminum intake your down to about 605lbs 350 chevy Chevy small block V8 575 (generic for '60s-'70s motors) Chevy small block V8 535 (1) ('59 Corvette 283 w/alum. intake) Chevy big block V8 685 Mark IV (all iron) you can drop 80 lbs to about 605 lbs with aluminum heads,intake and water pump theres not enought differance to worry about at about 30-100 lbs (depends on config) the distributor on the caddys in the front so it can be seated several inches more to the rear in the engine compartment, weight distribution might even be better Quote Link to comment Share on other sites More sharing options...
