Re: Edlebrock 60917 NHRA head
From the Edelbrock technical instructions:
Exhaust flange has been extended out .125” in order to provide dry exhaust bolt/stud holes. From NHRA classification, they carry a penalty (weight/ratio HP) for using those heads. https://edelbrock-instructions-v1.s3...rock/60917.pdf Last edited by Charles Stewart; 06-13-2022 at 10:31 AM. |
