Cool info Rob. There's also a pretty cool link......I believe it's on lt4.com but not sure exactly. Anyway, it shows two bone stock cars racing in the quarter mile. A black LT-4 compared to a red LT-1. I'm not sure where it is so I guess I'm not really helping any now am I??:D

Cool Page Rob!

Hey, They both have "short skirts" :D
You gotta see this page to know what I'm talking about!

Looking at those spec's, I gotta wonder if 1.6 ratio roller rockers would make a HUGE differnce on an LT1?
Add some head clean up and minor port-matching,new stronger valve springs..........probably $1,000 bill and you would be rockin' and rollin' up to 6,100 rpm's anyway.

Makes me VERY interested in them 1.6 ratio roller rockers :TALK
