specs- 242-248 lift .540-.562 lsa112 any comments would be great.

 

on 112 lsa your going to be blowing out the juice on the exhaust side. 114 would work better on the bottle. The 224/236 on 114 would work well with a power adder. I think there is now a cam the next step bigger. A 242-248 is a pretty big cam, what motor is it going into? What are your goals? How big of a shot of n20? Please give some more info on your setup.

 

It going into a complete forged 357 with stage 3 heads, 13.2 to 1 compression ratio. I want to run a mininum of a 175. I am plaining on a two stage system first stage 150 second stage another 150. this is a track only car so it ***** to wall on everything.

 

Your cam choice is fine. Nitrous doesn't have the same pressurization effect on the intake tract as a blower, so the 112 LSA should work with no problems. I assume you're gonna spin some RPMS given that size cam in a 357.
