New Backdraft Cobra help!

[stevek]

This is my first post so I hope I don't bore you with questions that might have been answered before.

I am in the process of buy a Backdraft Cobra and need some good advice.

1. My engine of choice as of now is the Roush 402R as I want to stay around the 500HP range. My main use will be mostly around town driving with some highway driving with an occasional track day and would like to know how streetable this engine is. I'm coming from a supercharged C6 Corvette which originally started out with a pretty wild cam which I changed to a ZR1 cam as it couldn't even go around 35-40 MPH without the car bucking and surging. Will the 402R Roush give me a fairly smooth ride at the 30-40 MPh range?

2. I also like the new Coyote engine but it's only 414 HP (certainly not bad at all) but to me it just doesn't look right sitting in the engine bay. Not nostalgic enough but that's just my opinion.

3. If I do go with the 402R what rear gear ratio might be the best choice for the kind of driving I mentioned above?

Any help would certainly be appreciated. Thanks in advance.
