I can't answer for the crank gear, but I changed my cam gear in about an hour without removing the radiator.

typically the crank gear is just fine - the cam gear gets chewed up. Its not like a modern engine where you must change both - put a new good cam gear on and go.

To answer your original question: With removing the light bar and radiator to provide good access with a gear puller on the crank pulley, I would estimate about 7 hours from start to finish. This assumes a very nice car where the finishes are of utmost importance to protect. It would include new front seal and pan gaskets.
This time estimate includes a cup of coffee at about 9:30 and 2:00...maybe more. I like my coffee!
Good Day!

2 to 3 hours is my estimate. The key is getting the camshaft timing gear lock nut off. If the shop has the right tool, then 2 to 3 hours is reasonable. This does not include changing the crankshaft gear. You should change the motor oil too as there is likely pieces of timing gear in it.

AS Seaslugs said I would not change the crank gear unless it is really pitted up from moisture. I have had them come easy and I've also had them be so incredibly tight on the key that I had to relieve the key pressure to get the off. There is a KRW puller I believe it's 6306 that was issued for V8 years ( you won't find the "A" one that does the job but you have to of course have the radiator off and front spring hand crank bearing ( spring U bolts removed) to use and the rear engine mount bolts removed and take the front of the engine up some. There's also an installer as the last thing you want to do is to beat it or hammer it on with the rear main thrust. It must be pressed on.

Just replace the cam gear and you will be fine. I;ve done them in 25 minutes and some that were stubborn a couple of hours. I would just say if you are a paying shop it's T&M and it is what it is. I use to flat rate them but don't anymore as the pan may need to come down for cleaning, etc....

When the car was new the flat rate time was about 4 hours, included removing the pan and radiator-- from chitons labor guide 1932
