Will this handle a 150 shot?
Eagle ESP Cast/Steel 3.750" Stroke Crankshaft
6.0" 5140 steel SIR full float rods with ARP bolts
SRP Forged Dished Pistons
Speed Pro Premium Plasma Moly Rings
Clevite 77 MS909P Main & CB663P Rod bearings
I want to throw nitro on but I don't wanna break my new build. What is the largest shot you guys would go without having a forged crank and using p series bearings? Ofcourse I would have the timing retarded and such...

You might want to do some research on the ring end gap. Pretty much all the piston manufacturers have you open up the gap by around .004" or so for light/moderate nitrous use. If your ring end gap is too tight and the ends butt together as the ring heats up when you're spraying it generally tears the top edge of the piston right off.
Other than that a 150 shot with those parts sounds reasonable to me. As long as you don't lean it out
Make sure you have ample fuel pump capacity to maintain pressure at wide open throttle.
Later, Michael

I have an awesome inline fuel pump and 42# injectors. I will buy a mallory unit or something like that.
The engine is already assembled but not in the car, how hard is it to adjust the ring gap?

you can pull one piston at a time or tear down the whole block. It would much earier to do it this way. you have to file and fit each ring to each cylinder and there are 2 per cylinder.

It was my idiot builder chose them. I didn't want dished, he seemed to think the CR woulda been too high with flat-top. I bought this engine already assembled at a good price. He says the CR is 10.6:1

Don't forget to go with colder plugs.
