Nitrous cams ?
Talking small blocks here...

What is the main difference that seperates them from others... n/a cams vs nitrous cams. Valve events, lsa, ivc/evc, lift etc...

Are there any off the shelf cams that can be used ase nitrous cams by altering timing events (advance/retard)
Is there a possibility to use single pattern camshaft in a spray application ?

At what point (big shot) it should become necessary to use a nitrous camshaft instead of lets say Comp Cams Xtreme Energy camshaft or similar ground on 110 LSA ?

If you use anymore that 150 horse NO2,you need more than a nitrous cam...pistons,new rings,special gap,excellent ignition system..

And if all those things are given, forged pistons, correct ring gap, good rod bolts and a bullet proof ignition system. What kind of cams are we looking at, and can off the shelf cam be used if it's advanced some ?
Talking about 150-250 hp single shot on 350 sbc here.

Sorry to chime in but would this particular camshaft be ok on the spray if advanced ?
And do i understand that if the camshaft is advanced 4 degrees. Does that alter all valve events by 4 degrees ? There for open the exhaust valve sooner ?

I have before used Crane Powermax 272/284 hydraulic camshaft with good result, but that was not with nitrous, only n/a. They all seem to have much split duration at 0.050" lift and adv. duration, they also seem to have more lift at exhaust valve for better scavenging right ? Then i assume nitrous likes big tube headers also.

Thank you sir.
How big of a shot you think it would tolerate ?
How much tighter should i run the valve lash ?

I have this thread here -
Hope you can give your self a time and read through it and tell me your oppinion as i don't want to steal this thread here. First it was about finding the right piston and rods for my strip car, but since i have that figured out i am looking for camshaft recommendation.

is it better to go hyd with nos or solid? or really does it matter with lifter type?
