Years ago I had a 68 Charger with 400/451 stroker and Indy heads and intake, with a dominator under the stock hood. I would think the Indy intake is at least as tall as TF intake, if not taller. Mine was more of a race car and I did not have an air cleaner on it, but everything did fit under the hood. Not too much clearance though. If you're using a 4150 carb and the TF intake is a little shorter than Indy's, it just might fit w an aircleaner. You might also try the shorter filter element with a drop base and also k and n flow top.
