Help me pick a cam
Im trying to decide between 2 cams right now
402 CI LS2
225cc Trickflow heads WITH 58cc combustion chamber
FAST 92
-10cc pistons so PTV shouldnt be an issue
current cam specs (240/242(.612/.612)112LSA)
Im looking at these 2 comp LSR cams
1. (251/259(.624/.624)115LSA)
2. (247/255(.624/.624)114LSA)
Which is a better fit for my engine? I would like something I could drive on the street, but it doesnt need to be easy to drive on the street. Is the first one too much for the engine? and of course, if you have used them, feel free to post your opinion.
Im also open to suggestions on other cams.

Keep changing the valve lift until you achieve a Mach Index Number of .50. That will be the valve lift you should have your camshaft made to deliver.
If you want street manners, your LSA should be in the 116 to 118 range.
Good luck with your new cam.

There is also a guy named Brian Tooley and he also sells spring kits that are incredibly reasonable. He is a great guy and will talk with you and absolutely tell you what cam you need and what lobe is best for your application. His number is 888-959-865 and his site is Brian Tooley Racing.
By the way he also has one of the quickest NA corvettes around. Super awesome guy. Literally spent an hour talking with me as I described everything that was on the engine and the weight of the car. Top Customer Service...
And awesome quick shipping...
