1981 silver/blue: two tone
I have recently purchased a 1981. The plaque on the console states: Custom made for JEM Enterprises WA80BF; 330 hp; 350 cu, 360 torque, 9.01 ratio. What is this saying? The VIN has the standard engine number, but the engine is really at 330 hp.

jbonifas,
Hopefully someone will reply who is familar with the Custom Shop that you refer to. I will say this about your engine, it is easy to make horsepower from a small block Chevy with a few mods. One of the obvious on yours is the compression ratio. The L-81 engine from the factory had a 8.2:1 ratio. The 9:1 ratio is a result of modified design pistons and head modifications. Stay tuned, I'm sure someone has answers....

Vette-less for now
Jbonifas,

Hello!! Nice to see another L81 guy on the CAC. Have you registered on the L81VetteRegistry.com website? Pls do so if you haven't. DDL-81 is correct. Someone out there will have some insight into you mod.

Enjoy........ Nut
