Its me again lol

The cam is a XE256H Comp cam, yes the pump is in the right hole and centered. I'm going to pull the carb tomorrow just to make sure the transfer slots are correct. Wont take but a minute. Afterwards I'll bump up the timing slowly, as it's a Summit Distributor and adds 20* of mechanical timing. This 8,900 lb truck likes to make the engine rattle at higher * of timing.4.10 gearing on 35s So ill take it slow. Until I can figure out how to limit the mechanical timing I may have to keep the timing low. How do yall feel about mechanical timing kits from box stores? Should I not even bother with them?
