Default Re: 302 HO vs. 302

Well, the 302HO or 5.0HO's go back to 1982. If you're talking about EFI versions of the engines, there are some differences.

#1 Firing order
#2 87-92 5.0HO's had forged pistons. '93s got the hypers.
#3 Camshafts
#4 '86 5.0HO and the 87+ non 5.0HO got E6SE heads (suck)

Yes, you can make a 302 into a 347. You'll just need a conversion kit (not a simple swap) and unless you're planning on adding heads/cam/intake, it's absolutely a waste of money. The stock parts will restrict your power production.
