Suppose to measure as 1.5 to 1.

They vary a lot though, usually in the 1.40 - 1.45 to 1 range.
1971 Charger R/T, 440 H.P., Auto, A/C Daily Driven (till gas went nuts).  NOW IN CARS FOR SALE SECTION: http://www.dodgecharger.com/forum/index.php/topic,48709.0.html

*Speed costs money son, how fast do you want to go, and for how long?"
*"Build the biggest engine you can afford the first time."
*"We normally wouldn't use a 383 for this build, parts and labor for a 440 cost the same."
