Black J,
I have a Richmond with 3.07.
Pulls in all 5 gears. Car did complain a little bit when I mistakenly tried to start it in 4th gear going up a hill. At the time I could not figure out what the heck was happening. Gave a bit more gas and chirped the tires and thought - good - problem solved. SHifted into what I thought was 3rd and it pulled like a champ even though it was in 5th. I caught on when I tried to put it into 6th
5th gear provides a nice cruising gear. To the point where you can have a very good conversation with the passenger without raising the decibel level in your voice. Dropping back into 4th provides you all the fun stuff straightaway again.
I claim no technical capabilities, but it is my understanding that the Richmond can handle the higher horsepower more effectively than the Tremac. (please don't shoot me Tremac fans
)
