I run a Holley red pump on the 440 in my 63 and its the one with built in regulation so no seperate regulator is needed. It holds about 7 psi and supplies more then enough fuel for my mid 11 car. It would work fine on a 318 also but some people say they are to noisey for them. Holley does have a new quiet pump also but I am used to being able to hear my pump so I know its working. Ron
