one other thing to consider as well is the brake pedal,if you're running cast iron manifolds and using the stock brake pedal it could contact the manifold...mine did...I had a buddy step it over about 1 1/2" to clear...rams horns would not work on my truck due to having a pacer front end under it..I had to use rear dump manifolds..I ended up using what i was told were off a early chevelle...They happened to have a dip (that i'm assuming was for the steering box)which was perfect cause thats where my steering shaft needed to go as well.......dave
