Can firing order determine engine block size? - 1st Bronco - 08-15-2013
I have a 1989 block (E9AE-8015-AA-82-D9) in a 1985 Bronco (VIN# 1fmdu15hxfla17630) I just acquired. The firing order is 13726548. In my Haynes is lists the 351 having the same firing order and the 302 having a firing order of 15426378. May sound like a foolish question but is it safe to assume I have a 351 and not a 302? I only ask because the seller of the Bronco said he was told that it was a Jasper 302 under the hood when he bought it. Very pleased with my first Bronco and drive it daily....just want to be able to talk intelligently when I walk into the parts store.
Thanks,

302HO's shared same firing order as 351's...standard 302's had diff firing order. did you look at cap and determine what firing order you have now? usually there is a #1 marked on the cap...and you have to go counter clockwise to check. 351's have a taller deck height and the intake should be a little wider than a 302. that block number you listed should tell you everything about the block. google ford engine block numbers to help break it down.
