351?

look at the sticker under the hood 5.0 is the 302 and 5.8 is the 351.. your truck is injected right look at the top of the upper intake (where your throttle body is) it will say 5.0 or 5.8.......

Look at your VIN number, N is 302, and I believe U is a 351.
BTW, up until the 89 model year, the upper intake manifold said Electronic Fuel Injection, and didn't have the distiction.

351 inside is right, they did come carbureted. The 302’s in 87 were all fuel injected.
The engine id/vin for the 302 is N
And for the 351 it’s H
302 firing order is 1-5-4-2-6-3-7-8
351 firing order is 1-3-7-2-6-5-4-8
Hope this clarifies something.

only mass air 302's have the 351 firing order. The old speed density 302s and 460's have the same order. The 302 was fuel injected starting in 1985. The 351 and 460 were fuel injected starting in 1988.
BTW, Orange Peel, the original carb on the 5.8L HO was a Holley 4180 with a 17" carb lid. Find out what carb you have and you can tell whether you have the 351 or not.

well, the firing order was the 302 order. but i didnt have time to look at the carb. ill get to that tomorrow. but it does kinda strike me odd as why its carburated. my dad said that he would take me to the guy that rebuilt it, so i will find out the story behind my engine soon. thanks
