Friend of my father inlaw has one and wants me to swap it to carb and put a cam in it.

Simple enough,.. how ever I have an E-303 cam I want to use.
87 302 Crown Vic used 1-5-4-2-6-3-7-8 firing order. E-303 is an HO cam that uses the 351/HO 302 firing order of 1-3-7-2-6-5-4-8.

Can I simply use the E-303 and wire the distributor as an HO? I dont see why it wouldnt work, but this is a grey area for me because I've never done it, so I am asking anyone else who has or tried. Will the HO cam work in a non HO motor?

Edit:
Also forgot to mention. 87 LTD Crown Vic have flat tops with no valve reliefs. Basically same as an 86 HO Mustang would have. So assuming we're talking about an 86, whats the max lift cam they will take before PTV issues? E-303 IIRC is .498 lift with 1.6 rockers.
