I am now part of the Pontiac club. All of my family is from MI and a lot of my family worked for Pontiac years ago so it was fitting to get a Pontiac of my own.

I found a 1967 Firebird that the owner was advertising as a 6 cylinder car. I found out that he was decoding the VIN with a Camaro decoder and it was originally a 400 / manual transmission optioned Firebird. It had no engine or transmission so I began my hunt for a 400 to go back in it. To keep the car "pump gas" friendly, I found a factory 9799914 RAIII 4 bolt buildable shortblock and "15" casting heads with a highrise, single plane aluminum intake paired with an M21 transmission. The intake has no castings or brand on it but it looks very nice and well-made. Included in the deal was a set of .030 Silvolite pistons. What would be a good choice for a cam? I would be looking for driveability for long trips but a good sound at idle and a good match with the rest of the build. I will be running power brakes so vacuum will be important but the manual transmission can handle some higher lift.

I also picked up a posi 10 bolt rear for a 70 Firebird. I will move the leaf mounts in slightly to match with the 67 leafs but I noticed that I have 2 "links" that come down from the rear pan to the rear end. They are currently resting on the top of the rear end so I assume that the rear end has already been changed since there is nowhere to mount these. Can somebody please share some information on these? They almost look like trailing arms that, I assume, mount on the rear end.

Thank you for reading and any support is appreciated.
