Dig it! I love the attempt at a ram-air snorkel.
I spotted the orange and white plates; do you have any issues with dragging a car across 50th avenue? Do you have to do an out-of-Province inspection? I know that Lloyd has some special provisions, like elimination of PST, but I don't know how it works with cars. My question also applies with dragging cars westward across 50th.
If I were to do an engine swap, I might be inclined to use an old Rocket, just for nostalgia. Another attractive option is to find a wasted '99 Silverado and use the engine, trans, computer, etc to go LS. Even the 4.8 would stomp on a 305.
