Chevy 366 problems

We've got a mid 70s C with a engine in our sprayer tender truck that we can't get to run right. It ran fine last summer when we were spraying but then dad used it to haul water to cattle through late summer and now it won't run right.

When you crank it over with the starter most of the time it won't start, it will sputter but only at a flat idle, if you give it any gas or choke it won't fire at all, if you pull start it it will start in the first '. I tried putting a timing light on it but the front engine mount makes it impossible to get to the dampner to time it unless it can be timed off the flywheel too?
