Looks great! I keep trying to find a way to justify buying one.

(1) Mike, would like to know "How many Ponies will I get over my current HP level?

(2) Is It required to Port match my "D"- Port Heads to the Bath Tube Manifold from the start?

(3) Here is a better description of my existing set up: Since I have a 1979 TA Scoop, open toward the Windshield, over the existing Tri-Powers on top of my 1976 Formula Hood and the "Poor designer" before me, "did not" account for the forward most Carb. height (the Scoop should have been installed more forward to fit correctly) I use a small Filter on top of the forward Carb. The Center and Rear Carb. clear well. That being said, I run a 1979 Pontiac TA with the 428 HO. "Will I have any issues fitting the Air Filters, if I go with the 409 carbs"? What is the 409 Carb? "Is it an exclusive type, just for the Chevy 409"? Do I have a second practical choice to Carburation?

LOL! True!

I have a long list of reason not to. Like I have a big pile of parts to buy to get my car back together.

Don't feel bad, I have to rebuild the TH400 on my Vehicle and I am reading all my saved files in order to accomplish this task. My roommate is doing the same thing. Soon we will watch some Videos and build our confidence up. I have the parts to rebuild it, but I am sure we will find some hard parts inside to replace. This is first in my priorities and foremost.
