Help on engine "suffix" code.
I got a 350 engine block casting numbers 14093638. Now its supposily from a 89 Iroc, But Idk the casting numbers just tell me 87-94. (could be truck car etc) but i herd the "suffix" code will tell him exacly what its from and exacly what year. Can some help me to where it is at? or how i can tell what this engine is from? Thanks

There should be a bunch of numbers stamped on a pad in front of the passenger side head. They're usually hard to read because of dirt, paint etc. Get all those numbers.

You can cross reference the numbers on the pass front of the engine block at nastyz28.com

Nasty28 doesn't have a lot of the newer suffix codes since he deals mostly with second gens. It may be there but probably isn't.

V0303SNA in the number on the pad. I thought the s was a 5 and it confused the hell out of me, and I thought the engine was a 89, so i was looking for a z because 89 suffix starts with a z, But its SNA, And It say its a 1987 350 TPI. So I guess its from a 87 Iroc 350 car.

SNA 1987 350 225hp TPI L98, a/t
That's what my car had under the hood 10 years ago
The engine is in a 66 Chev pickup now that belongs to the guy I bought the car from.
