I was wondering what were the mods I would need for a 75hp dry shot of Nos. You can look at all my modsin my signature. Can you make it so when you hit a certain rpms it will inject it? Can you also put a toggle switch to turn that feauture on and off? How much is install, or could I do this myself? I rebuilt two engines before. My Lt1 and a 400 small block. So I am resonably skilled. Is tuning required? Is there a good chance of blowing up my engine? I just rebuilt it so it doesn't have any miles on it. And I wont use it till its broken in. Thanks.

The engine should handle a 75 shot with no problem, as long as you follow all instructions that come with the NOS kit, everything is installed correctly, and the kit is for your engine. If you are not using a kit, then you are on your own, and better know what you are doing.

Yes, I would be using a kit. But its probably a mod for the summer, not now. Thanks Pete.

tune would be a good...tune is always a good bet tho...
