87 33.5 ft Coachmen
460 ford 600 cfm Holley. This engine had severe vacume leaks. I fixed those then the carb began running really rich. Replaced the main jets went from 63s to 60s 16 inches of vac @ 5500 ft ele. 6.5 power valve. No power on hills still running really rich.
thinking about a new 750 Holley and a msd ign system.
any suggestions ?
thanks

I had a Holley on an 84' 460 Ford, constant problems, swapped it out for an Edelbrock (#1411,they have all the parts to adapt it, you may need a different model). All the problems gone, runs like a dream.
