Selection of Replacement Distributor 1975 truck 350 sbc

[Fredthecat]

I need shopping / install tips for overhaul/update/ replacement of stock points distributor for 1975 Chevrolet truck 350 V8.

Installed in 1964 C10 LB pickup with truck 4 speed, Holley 4160, headers.

As purchased: Runs rich, rough. #5 cylinder wire misfires, found cap terminal green. New plugs/wires.

Thinkin pull / rebuild/ or junk distributor, appears stock with points /condenser Axcell cap.

R&R Holley 4160 too.

Distributor looks tight against firewall for install in 64 C10

Are there good (NAPA) better (SUMMIT) $$ best (Unknown racing) ways to go for new distributor? Get rid of points? Replace with what? Don’t see entire MSD system in future.

$200 budget.

Need regular reliability and low end torque more than performance for general old driver pickup truck.

Sources? What works well? Whats in your SBC?
Thanks
