Hooker Super comp D-ports and 4 speed?
I have a 77 Trans Am that I am installing a 4 speed from another 77 Trans Am into. I also wanted to install the headers that I have at the same time which are the 1 3/4" D-port Hooker super competition headers for a 70-81 Trans Am. Am I going to have any header issues with this 4 speed install?

I can't answer your question directly, but High Performance Pontiac magazines latest issue, March 2008 issue, had a excellent article dealing with just what you want to know. John.

Not sure if this helps you at all but I have Super Comps in my Ventura with a 4 speed and no issues.

Ran Super Comps for years on a 71, not problems. I know there's some generic notes that come with them that mention a few mods that 'may' be required, but I never had to do any.

I've run super comps in my 76 T/A w/455 and a ST-10 4 speed for 20 yrs. and several engine removals. No mods were required @ all. However, if you plan on running a scattershield (highly recommended on any powered up 455) then some minor "flange" mods are necessary( easier prior to eng. install). Larry

Ah, trim a blow-proof, that may be true, I usually trim mine off from like 4 o'clock to 8 o'clock. Maybe around where the clutch rod goes may need triming too. No biggie though...

In using a Lakewood Scattershield yes! Notch the clutch rod area. One also needs to trim the flange to fit a standard oil filter past the guilty header tube (or use a narrow filter like NAPA's #1522 instead). Larry

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
