"It is half the upper plenum off of a stock 2.8L intake and half of the center section from a 350 TPI engine. I will be using the throttle body from the TPI setup. That is 2 throttle plates of 48 mm versus the single throttle plate of 48 mm that is on the car right now. The section of the 2.8L that is covered by the other piece has been completely cut out. The inside of that area has been bored to remove as much restriction as possible."

That's pretty cool, but wouldn't it have been easier if just swapped in a V8?

Jeff, I bought an engine this past weekend.  Hope to get it within the next few days.   :D

If I had a f-body V6 (I did have one), I wouldn't bother with it, V8 is the way to go.  Just wanted to post this guy's project.  Not sure if it's worth it for the gains, but interesting nonetheless.

I did a v6 --> v8 conversion, wasnt pretty but it ran...then i yanked the engine and parted the car out =)
drop me an email bout the 350 ya bought, we'll set up a date and get ya TA back on the road.
