I agree with rusty.i have had both and I didn't have any problem steering my 73 big block dart and the 73 with tti headers were no harder to work on/around than when I had the 318 in it.wirh the tti headers drill a hole in the inner fender for number 6 plug.makes it a lot easer to change the plug. Op I would like to see some pics of your car. I have a 73 duster I am building
