Hello everyone. This is my first time to ask for help. Ihave a 73 caddy and it had a 500 in it but I bought it with a blown 500, These people were gonna crush it, OMG. so I saved it and I went to a local salvage yard and I thought I got another 500 but turned out after I got in it the car that it was a 425.Had to switch some parts to make it work, I wasn't about to take it out after I put all new gasket on it, heads, intake, oil pan, new oil pump, etc. so anyway I got it in , then I had the wrong heads on , note: 500 heads DO NOT work on a 425 block, next I had to have to carb, rebuilt and finally it runs, but I can not figure out where all the vacuum lines go. some are missing, etc. where is all the wiring go. I have the altern. wired I think. any suggestions

Yes, just chill out and someone that knows about the swap will chime in.

When I swapped a '68 472 intake manifold on my '79 425, it was pretty painless, only 1 or 2 holes on the intake had to be plugged... and the engine lost EGR.

BTW It is a 500 CID engine... not 501..... 501 is a sticker

I just went through what you did, I kept the old 500 intake though, maybe put the 500 intake back on, I also took off all the smog hoses, and plugged some carb stuff, but all I had to hook up is the brake vac, vac adv, trans downshift, and air cleaner. Hopefully this helps. Thanks
