I'm currently in the process of building my new motor. 383 similar to Car Crafts (http://www.carcraft.com/techarticles/84459/), hoping to get similar results.

I am going to be using an Eagle Forged Crank, Forged Eagle H Beam rods, and Forged Wiesco Pistons with ARP Fasteners.

The question is, how long do you think the bottom end will last on a good shot of Nitrous (probably around 300)?

I was told by a friend using the same bottom end for an all out race car that he gets around 75 passes on a 600 shot. Since this is a street car I would like it to last a bit more than 19 miles but I think I would like to run a 300 shot.
