Absolutely! But in general, an LT1 blower cam should have at least 10 degress more exhaust than intake duration. IF you are dealing with stock heads (not ported) there is no point in going beyond 220 degrees intake duration with lift in the low to mid 0.5" range. Way back when I was running an S-trim with stock heads I tried a couple of cams and found that the one which worked best had ~215 degrees on the intake. If you want details, send me an email or a PM.
In my earlier post I alluded to headers. A good exhaust makes a huge difference on a blower car. In my case, I saw a gain of 40rwhp going from stock manifolds+stock cat+Borla to mid length headers with dual high-flow cats and a a cat-back system back when I was running stock heads.
