Fitting TTi headers on a 273
I had them up for sale a couple of times and should follow up with the guy who bought them as far as fit and performance since they were going into an A-body. I had them coated with zirconium dioxide so curious about that as well. People have been able to fit the TTI shorties into A-bodies, I just couldn't do it on my car without a bunch of mods. Maybe certain combinations don't work out as well. Maybe changes have been made since then - the headpipes certainly have been.
It's been a while but I think TTI always intended these for cars. They do not fit '66 and earlier. TTI had made them to fit them in a late 60s or early 70s A-body so I wasn't expecting complications. After tying Rob's lift for 3 days I made the decision to cut both our losses. There were at least 3 more modifications it looked to be needed to make them work. My car may just be on the tight side of certain production tolerances. The 340 headpipes made by Accurate hung low, and the distance from distributor cap to wiper motor is pretty tight. Not complaining - its good to have the engine as far back and low as possible.
