440 Need help figuring out what cam is installed

Mine had Schumacher tri y on there when I bought it. For the engine that is in the car they would have been fine.
I went with 2 " tti and they are in the car now. Overkill for this motor but I have one being built that can use them.
Header fitment depends on whether you are running power steering also. Tri y will fit with power steering,Tti will not with factory p.s.
Your motor would do well with the 1 3/4 Tti or the tri y's.
