Nitrous help
The first time I used nitrous, it was on a bone stock 74 Dart with a 318/904/2.93 pegleg 7 1/4. Just added a LD4B intake with a Holley 4bbl from a 440 engine. and the 125 nitrous plate. Just "T"ed the fuel from the stock mechanical pump. Car was a daily driver. Drive to the track, open the single exhaust pipe before the muffler, put on a 22.5 inch slick, and run high 13's. Ran it for 4 years, then removed the nitrous, and sold the car. Never had a problem or broke anything. At 100-125 hp on a V-8 you don't need fancy. Just make sure everything is in good condition, and don't run too much advance.
With my 318 I was only adding .39 hp per cube
On my 170 slant I am adding 1.32 hp per cube (225 shot), which needs fancy.
On your 360 you are only adding .28 hp per cube.
