Figure out what your compression is now or at least where the piston sits in the bore. Know for sure where everything is at. Know for sure if it is the 12-1 domed piston or not.
I don’t think Edelbrock has it as a Reggie trade mark.
For an example, ALL a Chrysler big block intakes are of this design from the day they were born.
