Keith-
I'm looking at either the Backdraft or Superformance Cobra. I'm leaning toward the Backdraft basically from a cost perspective. However, I'm unsure which is the better of the two. I plan to race the car on a track once in a while to see what it can and bring it to the quarter mile strip, as well as doing some street driving and car shows. With respect to the engine I know I want a big block there is no other. However, I was thinking of going with the F460 with about 550hp (and you get the most bang for your buck). Any thoughts on this? I know its a heavy block for this little car and there could be a weight distribution although I'm not that concerned. I am not expecting this car to handle like a Ferrari.
Lastly, I was dirving my car the other day and when I stopped at a light there was a 66 Box Nova with a big Block. It had a very strange thumping cam sound. The best way I can explain it had a very slow cam strock. The sound was from the engine not an exhaust sound. And when he got on the gas it took off like a bullet. I know this is very brief but what in you opinion would give a big block this sound.
