I am using a modified 57 four barrel intake ( oval ports ect. ) and wondered what kind of spacer I should use open, or four port and how tall. Not sure of the carb yet, but leaning toward a 600 cfm holley.

Thanks in advance,

Richard

What vehicle?  Trucks and 55-56 cars have a lot of room under the hood.  'Birds and 57+ cars have clearance issues.  I run an open 1" phenolic spacer.

You gotta have the right tools and know how to use 'em.

Thanks for the fast reply, its a 54 Ford Ranch wagon, lots of room for a 1" spacer.

Phenolic four hole, up to 1" Don't use an open spacer for street use.
