<VV> DIFFERENTIAL RATIO COMMENTS

[Dennis Pleau]

I've heard a lot of recommendations years on the VVs to install a 3.27:1
with a four speed and then use third gear as "drive" and forth gear as
"overdrive", which is not technically true.  

I can't imagine that a PG which doesn't have as low of a low gear as we
would wish even with a 3.55:1 and then shifts to "overdrive" would be a good
choice in a FC with the ballistics of a brick and the capability of carrying
3/4 of a ton.

Hi Tim, I am getting ready to install a 3.27 PG into my Rampside. I
currently have a 3.55 PG with a 95HP 1965 car engine (that recently
shattered a valve seat). WHAT A MESS! I'll keep you posted.
