whew....that was a read.

with the cast pistons, I would think that the tops you would want to do would be about 125. Above that is kinda risky unless it is efi.

with forged pistons I personally have gone as high as 250. (ARP rod bolts, ARP main bolts, GOOD head gaskets, and a quality fuel supply) once again it depends on the tune you have.

I wouldn't even worry about the crank unless you go over 200.

probably your worst enemy on this motor would be too many RPM's and the nitrous. as for the timing controls and nitrous controllers, you can get away without using them if it is mostly street driven. The main reason for them is to eleminate variables while you are trying to do bracket racing.

Simple and clean with the right supporting systems is the way to go no matter how much nitrous you use.

Just my .02
