One rule of thumb is any Edlebrock manifold that Chrysler used ( 69 440 6, late 70, etc)had Edlebrock and the casting number embossed on them in that time period. And they made stuff for all the manufacturers. I think the 396 Chevy had that manifold with the middle machined out that became legal and I think the 70 350 Chevy had a couple of alternate manifolds. Any know how that came about. That part number is definitely that time period. Being as NHRA has the Technical Service Bulletin number from 73 or 74 that allowed that piece, I am trying to find someone who has all those old TSB's. I think they (the intake) have been out there for some time. Anybody got one and where and when did you get it. Anybody got a factory cut manifold for the 396. There are a couple in my shop that belong to Helms. When did that happen. I know there is an NHRA letter saying it's ok. Anybody got that while we are talking. Just as soon get all the old stuff out of the system. Then we can start with the 80's and 90's crap and then we can move in the 2008 and later stuff. Somebody order pizza and we can watch the Super Bowl while we do this.
