Anybody have tips on how to do this. Are the exhaust and intake manifold one unit? Can I just remove the carb and the four bolts attaching the exhaust pipe and then the bolts to the manifold, or is there more to it than that?
I'm trying to decide if it's something I can realistically do myself, or should I bring to a shop? Thanks.

Yes they are one unit. Remove the carb, exhaust and various lines. Remove the nuts that secure it to the block. Pull the manifold assy about 1 1/2" away from the block, then up till it hits the bottom of the heater box, then forward and out.

Thanks.

I would suggest that you use an engine hoist or two strong friends, also put all kinds of padding on the fender. IT IS HEAVY !

Thanks for the tips. I ended up keeping the carb on, disconnecting the throttle linkage, fuel and vacuum tubing to the carb, the big vacuum tube to the electromatic clutch, the shroud over the fuel pump and the tubing to the fuel pump, and removing the drain tube on the bottom of the intake manifold. Then you can remove the eight or so nuts that hold the whole unit on the block. It's possible to get a 9/16 box wrench on all of them, although it's a time consuming job. I was able to lift it out myself, but if I had to do it again I'd get somebody to help me. I had my son help me re-install it. All in all it wasn't that difficult, I don't think I swore once (really). And the good thing was that it fixed the problem of a funny tappet-like noise the engine had been making.
