1970 buick electra engine miss firing

after years of storage i started up my 1970 electra 455 without too much trouble, but the engine definitely misses fires and is sluggish under load. i have replace the plugs, spark plug lead, the dist cap, coil, condenser (dont think i needed to) points and rotor. its better, but still missing at idle. whats my next step?

Feed it. It's hungry. Clean the entire fuel system.

Hopefully, you aren't running it old gasoline.

i think i'd replace all rubber fuel lines while you're at this. 45 year old rubber is getting kind of sketchy by now.

and you definitely do NOT want to have a fuel leak.
