You will find a long piece of wood and 3lb mallett in most mechanics toolkits. GM harmonic balancers of our vintage are either iron or mild steel and wood is not going to harm it.

No need to remove the engine to do a cam swap. I did mine in an afternoon with the engine in place. You have to take at least one engine mount bolt out to lift the engine slightly so the cam will clear the crossmember above the steering rack.

I used a long bolt and a lot of washers. Tighten bolt to pull the balancer on a little way. Take out bolt. Add washers. Tighten bolt. Add washers...
When I had a '78 Corvette I used a hammer to tap it on, but there is no room for that on a C4.
I just found out that washers are arandelas...

I'm doing a cam change right now and I did my balancer removing the exact same way Agent 86 did. In fact I'm almost convinced that is why that hard line has that bend in it like it does. I was even able to use my impact wrench to remove the balancer but my radiator was not in the way.

Another case of our cars being the same but different, my cam came right out with no interferance from that crossmember, It almost came completely out of the block before I had to move the condenser.
