Good stuff Smitty. I tell ya, I just got back from 6 months of training down in Texas for the USAF. Got in my truck and I really am impressed with how the 305 with a few mods runs. It's really plenty for I'd say a daily driver and I still have more simple mods to do. I could only imagine a 350.
As for the Holley TBI, I've heard it's a waste.... on relatively stock engines. The stock TBI will flow adequately with some of the simple mods (Ultimate TBI mods: shaving the ridges, the rivets on the butterflies, etc). But I guess the Holley has an adjustable TPS? which I guess is useful.
