Anyone been using a Offenhauser 360 on a chevy smallblock ! Changing to a offy intake now ! engine is a 283 0,30 bore ported powerpack heads. I want to match the intake with the heads but dont wanna remove the heads ! Cheers from the swede with ****py enlish !
I prefer a (any) dual plane intake for street usage, especially on a small displacement engine. Tried a single plane (open plenum) long ago on a 351W Ford and it was very sluggish in the bottom end. Stick with under 600CFM (390-500) vac. secondary carb also.
