Nitrous cam for carb'd LT1
Nitrous cam for carb'd LT1 I'm building an 85 Monte SS for drag racing and was wondering what's a good nitrous cam for 150-200 shot. It has ported iron heads, Holley 750DP, Turbo 350 with 3500 stall, 410 rear, 26x9 Hoosier slicks. I want to keep te lift below .600 since the springs are rated up that lift. Thinking about making a custom intake manifold since I can only find dual planes for the engine.
If you want to run a carb you will be better off starting with a gen 1 engine and not limiting yourself so severely with intake choices.
Also on a small shot like 150-200 a "nitrous" grind would be a mistake, you will lose NA power with no real payoff on the bottle. Maybe add a little exhaust duration but do not get carried away with wide LSA as is the usual mistake.

Why would a nitrous specific cam be of little use with 'only' 150-200 shot? I know these cams usually need more lift and duration toward the exhaust side. Its going to be a bracket car off the bottle, so power loss is no problem. I just want a cam with maximum efficiency for nitrous.
JPH thanks the tip!

Start talking a 300 shot then consider a true nitrous grind.
The "wisdom" of needing a nitrous grind for 150-200 shot is comparable to the "wisdom" that the computer needs a 112+LSA, not atall the case.
The standar 112 is already so far spread from optimal anyway that you could call the off the shelf NA grinds nitrous grinds.

If just buying a "custom" Comp or Crane then the price is usually about the same. Price only goes up if you enlist a third party to help you spec the cam.
If you are putting some carbed crap intake on the motor you need to visit a carbed site to talk about cams anyway because the LT1 intake changes the way the engine responds to a cam, particularly the rpm range it will need to turn.
Like I said though if going carbed just put a gen 1 in it and make life a little easier. The LT1 without it's injection is just a smallblock with limited intake and waterpump choices.
