If you want to stick with Lunati go for the 50132 for a N/A cam (317/330 @.020" 283/291 @.050" .680"/.632" 106°) or use the camshaft below

307/313 @.020"
278/284 @.050"
199/204 @.200"
.723"/.723"
106°

With the 300 shot, if your wanting max performance on spray, I would widen it up some and take a little intake duration off (~8°) or a different profile like cam below

For spray,,,
298/314 @.020"
268/276 @.050"
191/190 @.200"
.670"/.625" with 1.5's
.715"/.666" with 1.6's
108° lobe center

If this is going to be a heavy nos set up I would use a custom cam designed for you and not a off of the shelf grind, I mean it's only a few dollars more and well worth it imo. I would be more prone to saying a 270/282 @.050" cam on a 112+4 would be more along the lines of what you would need imo.

that lunatic is little big....and to really make your engine snort you'll need to slide some titanium in there.

How is this if I change the lobe to 112 or 114 ?


Dur Int-Exh: 310/322
Dur @ .050 Int-Exh: 275/286
Lift 1.5 - 1.5 Int/Exh: .652/.643
Lobe Center: 110°
Valve Lash: .030-.030
RPM Range: 4500-8000

And what would this be with a 1.6 rocker?

Second cam I posted, 110° to 113° lobe center would work well depending on a few things about the engine
