i have a 59 apache with a bored out 350. I just put a 650 holley spread bore q-jet style replacement on my holley spreadbore manifold and it saves me alot of gas and has shown very noticable horsepower gains over the old edelbrock 600 performer i had. the model # is 4175 and they run about $300 brand new. oh and dont forget to ask from a 5/8 to 3/8 fuel inlet with it.
