I have a NOS ls1 kit dry shot sitting in the garage right now.....Im going to do a 75 shot......would a 75 dry shot be safe even with the stock intake manifold....Someone told me that i would need an ls6 manifold before i did this....but im not to sure....anyone know???? thanks

 

You should be fine with a stock manifold. I'd still upgrade to an ls6 manifold though sometime down the road.

 

I ran a 115 shot on a cat back only 99 Z28 and it ran great.
11 MPH pick up in the 1/4.

Don't worry about the intake, worry about your fuel system.
