Now for that class, what other engine limits do you have? Obviously not the intake....
Cast iron heads with factory minimum volumes and stock valve size, Factory rod length, +.015 stroke max, any cam and valvetrain, any intake as long as it fits underhood, and carbs must be inline as street hemi, 625 afb's, 10.25 compression.
Very similar to a SS/AH motor, except for the compression(12.5 to 1 pistons) and carbs. AH has to run an minimum offset on their 770 holleys to simulate a cross ram.
