    Cool wagon, my wife hates wagons, so I am SOL. Smart move going to a 4L80E, the 4L60E sucks behind any sort of power. I plan on 3.90 gears and 29 inch tall tires to make the deeper .75 OD more ideal in my 70S.

    Almost done... just need to plug the holes.

    The throttle body flange/inlet was opened to 92mm to match the Warr TB.

    One of my biggest concerns is with over porting the manifold (ie. shortening the runners may cause a reduction in low-end torque) so I approached it with caution. Effectively I only removed the NVH tube and smoothed the rail at the runner openings to be as close to even as possible.

    One thing I did leave in was a piece of the ramp at the halfway point, this might help kick the air up off the floor toward the rear runners (or it might not do a damn thing).

    The runner outlets were squared up to 1.05" wide and the gaskets opened to 1.07" (removed the silly ramps) to closer match the TSP heads (1.075") and allow for an easy transition and misalignment issues once bolted down (things are never perfect).

    Another reason I am not too vexed about going full out on this port job is pretty obvious: zippy juice.

    Epoxied the caps on the top and rear. Bucked out an aluminum decorative cap over an old bearing race... guess it really serves to keep the plug from getting sucked in if the epoxy fails.

    And then set it in place - there doesn't appear any major issues at this time. Other than the fact the F-body throttle/cruise cables are in no way compatible with the truck cable bracket.

    Somebody hand me my welder...
