So I was trying to figure out H.P. on my 1967 Cutlass Convertible.330 engine.
The code on the Block says 330001 LH
A website said that "L" means Low compression and "H" means 4 barrel.
I thought that all 67 Supreme's were High or Ultra high compression.I believe that would be a "G". Doe's anyone have a clue what the main difference is and is there a H.P. difference.I'm still trying to figure out what the horses are on this model.Would the vin no. give a clue? It's all original and has gold valve covers with Jetfire on them.It's a 2 speed Tranny.Also I think that's a 1 on the 6th digit.I'm sure "330" represents the engine size.I'm not sure about the "001"

Thanks from Chattanooga Tn.

 

What code is that you are referring to? Where is it? That is not an engine block id code. Nor does it seem to be an engine unit number that would be located on the front of the passenger side head. Only the engine unit number *would* identify what engine it is.

 

AAAAAAAARRRRRRGGHHHHHHH!!!

Not the dreaded parallel thread phenomenon again!
