Couple things, Capt'n...

First of all, seein' as God is gonna get your voice better, He is expectin' some new material so...

...get busy!!!

Secondly, seein' as the Chev don't get much drivin' of late me thinks that part of yer timing problems is in a gummed up plate in the distributor that won't slide when the vacuum pulls in... That ain't gonna allow you enough advance and that means yer Chev is gonna run crummy... You know, kinda like you of late... lol... Spray the plate liberally with BrakeClean or CRC to free it up and then a little lithium (white) grease on the plate and a little points lube on the lobed part of the distributor shaft where the points go up-n-down... Yeah, you do that that yer Chevy will run almost as good as a Ford... lol...
