It will fit. I promise. All 302/351 cams will interchange, you just have to pay attention to firing orders and this one is ok.

Also trust me on this, with 392, this cam will peak at around 5800. If you go to a bigger cam (which BTW, an XE274 is not a bigger cam) you'll be pushing a hydraulic roller a little higher than what I'm comfortable with.

Why do you say the lift is too much? Because of coil bind clearance or piston/valve clearance?
