Gents,

I am getting ready to pull out my worn and tired 440 in my 72 Duster for a newly built motor. I am currently running 1 3/4 TTI headers with the factory power steering mounted to a Spool type K-Frame. I would note that I feel this set up mounts the engine a little higher than my previous set up which utilized the biscuit style mounts. I very much want to run TTI 2" headers as this engine dynos 547hp and the 1 3/4 headers are likely gonna be restrictive. I know fully that the 2" headers will not work with the factory PS box but I have not found much information whether or not they headers will clear the more compact Borgenson box. I do not expect any header to be a drop in procedure but I dont want to hammer a tube to 50% of its size to make it work either.

Has anyone had success with mounting 2 in TTI headers with the Borgenson box in an A body without cutting and relocating tubes?

Thank yo5
