Well, ****! Despite decent planning, I've gotten myself into a spot where I'm getting indecisive. Supposedly, my 357W has a flat tappet XE284H with hydraulic lifters in a '70 block (oddball I know). I think that cam is just too big for a street driven car. I don't want to pull the engine, because if I did I'd probably be better off rebuilding it to a 408. I want to try the Sniper with what I have, as is. I also swapped my heads for a set of AFR185s, and bought some Doug's longtubes (that don't fit even though I called to confirm they would). My mechanic recommends sending the headers back because I already have mid length headers. I was hoping to drop temps (jet-hot) more than pick up HP, but he thought I'd be fine with what I have and said the jet hot shouldn't make as big a difference as everything I've read online.
So, I'm looking for opinions, mostly on the cam. Do I go forward with it (it was in the car before) and hope the Sniper can manage, or bite the bullet and order a better match for my combo?
