How much total timing did you run?

How much did your lash grow from cold to hot?

Only 36 degrees timing, lash cold .16 hot .024
@33 degrees made about 27 less HP
This engine will only idle in & out of the trailer

Kind of shame that...but understandable.

Yes, that's what I was thinking too, but again, a car that is as valuable as this one would be hard to abuse. I'd like to put that in my Camaro for a little while and see what it would do.

I don't think this engine is in any car from what I gathered so far. But, I am curious if it is from one of the original '69 ZL1 cars - I believe that was inferred in previous thread or maybe I misunderstood....
