My niece has a 95 Caprice, the motor was swapped but she has no idea what it is. The vehicle vin says 4.3 but I know enough that it's not that. It has the look of a ram jet style small block. It's not a TPI. No individual coil packs.
Questions I have are - where are the casting codes located on these newer blocks? (at least new to me) and Is there a site for casting codes ?
Thanks

GM put a 4.3 GEN II V8 in the caprices It looked just like the LT1
I remember seeing an article about hopping it up in a magazine

TPIs had a regular distributor like the rest of the Gen Is... Maybe I just read it wrong? But yes, the 4.3 "Baby" LT1 came in the later B-Bodies, and I believe those had a single coil as well. Also, the LT1 intake doesn't have the large curved runners like the TPIs do.

Does it look like this?
