I've been thinking of getting a cam and thought about a custom grind. 230/230 .595/.595 at 112 lsa with 1.5rr

Any ideas on what that would give me? Is this the right path for a mostly NA motor with possibly some n20.

The heads will eventually be ported/polished but for now it'll be on a upgraded valvetrain only.

 

Looks like a Solid Roller Lobe with that kind of lift and a 1.5RR, Seems odd to have that duration even and the LSA that high together.

You want a split duration cam for nitrous.

 

im running a 240/240 .595/.595 112 with 1.6's....Yes you want at least 6 degrees more on the exhaust side for n20..

 

the split is more dependant on flows, curtain sizes and lobe areas.... that can get a little bit more in math than you need to get. A N2O cam usually likes a lot more exhaust duration than even a NA motor, and based on calcs like that a typical SBC likes more duration on the exhaust.
