If you have 8 spark plugs, you either have a Z22 engine or a Z24 engine. It should say on the side of the block in the front driver-side corner. The Z22 was in trucks from 81-82 I believe, and from 83-86 is the Z24 stock. I might be a year off in there, too. the Z22 is a 2.2 liter, the Z24 is a 2.4 liter.

The 2.0 liter L20B only has four spark plugs.

engine cover shouts Z24.... and so does the year of your truck

Z24

The year screams Z24. Captainzeros, there are Z18s and Z20 also that carry 8 plugs, yes there are the L20Bs in some trucks but the year doesn't correspond. I believe some up to 82 carried the Z20 or L20B but I can't be sure of the year.

well i put it back together and i think the head is cracked so i yanked thhe motor and im tryin to find a z24 now.

[captainzeros]

I believe 81-82 were the Z22 and 1980 was the L20B.8 plug L motors are news to me, learn something new every day.

As far as years corresponding, I learned long ago to never assume something is going to be stock, be it cars or anything else. I'm about the fourth or fifth owner of my 720.

L motors and Z motors use the same block but the L motor uses 4 plugs, whilst the Z uses 8 plugs. There are some CA engines that use 8 plugs as well but these are not for emission but for added power as they fire together.
