[FUNFER2]

I've tried calling BT today, but they must be out of the office.

I would think their OEM and the Edelbrock would be the same as the originals head., and the high risers being the taller ones. I hope....anyway.

With my original 428 build I used the RPM manifold, when I change to the Vic Jr. intake, I had to mill down the carb. surface, either 1/4 or 3/8". (can't recall) I really don't know if that changed the TQ too much.

So, I'm concerned and will talk it over with Al at Blue Thunder.
