Everybody heard of them? Good.


Anybody know what it means exactly?


You are about to find out.


Take a two barrel V8 intake manifold (factory).


It takes 720 degrees for each cylinder to get an intake pulse.



Each cylinder gets an intake pulse every 180 degrees.


Now you know.


From early 60's Hot Rod magazine 'Carburetion Systems' booklet.


Also says log manifolds are for all out competition.


Gotta go!
