    Additional power changing to 4 barrel carb

    Thank you, so basically going from the stock rochester 2bbl to a 4bbl holly would add about 15hp, so to get best results I would have to try to find a intake from a 350 to go with it.

    Additional power changing to 4 barrel carb

    So i take that changing carb will add very little extra power maybe 5-10 horses max? Due to this being bought by my dad new in 1978 I would like to keep as much of this original. Besides some modifications to get some more power out of it. Would like to get at least 200+ horses if I can...

    Additional power changing to 4 barrel carb

    Does anyone know if a stop 78 305 would gain any power if I upgraded from 2 barrel to a 4 barrel carb? if so would it be noticable? Also how about if I converted to fuel injection? would that add a decent amount of horses? if so how much estimated do you think? Trying to see what options I have...

    Blower motor running anytime key is turned

    I dont think this is how its supposed ot be, but anytime key is turned you can hear the blower motor turn on very low. When you turn hvac controls on it goes higher. But if I leave at low it stays same. Any ideas on what could be the issue here?

    Stock 78 LT with 305

    My dad bought new in 78 said it used to light tires up no problem. Even before it was parked in 2015 it could spin tires, thats why I ask.

    Power windows very slow

    Another issue I am having. The power windows are stock factory option in my 78. They rollup very slow after getting about a 1/4 way up. I have tried adjusting the retainers on the door with no change. Could it be possible both motors are going bad? They will go all the way down and up but are...
