I have a iron-block 5.3 bored to a 5.7 (3.905). It has Lunati forged rods w/ Diamond 10cc pistons. Crank is stock but the bottom end has been real balanced. Head wise I got a set of p/p 241's for now. Its gonna be on the juice 150/200 shot but Im trying to decide a cam size... MS3/4 or close or a custom grind...

 

If you're choosing a cam for best nitrous performance, you'll want a bigger split than that. So out of your options, do a custom grind.

 

Get a custom grind if your looking for the best response to nitrous.

 

I talked w/ TSP and they recommended the MS3... Said it responds very well to the juice. I guess I will make a few more calls tomorrow...
