Hi guys,
New to this forum, need some advice on cam sizes for my ls3
My 2012 e3 clubsport originally had a lumpy cam installed by active automotive in WA, went well had 370rwkw, until it snapped a valve spring, they used single bee stings springs in it, which my mechanic now says they should have used doubles. My mechanic pulled out the cam the only numbers on it were "055" does anyone know what size it is? It's a custom grind cam
So now I'm up for a rebuild and have desided to stroke it to 418ci, I need to decide how lumpy I should go, what power have you guys got with the 418ci with what size cam? my car was lumpy before so im not afraid of the pig rooting
Also should I get the 102mm fast manifold and fuel rails, and throttle body? my mechanic says the stock ls3 manifold will start to restrict it for air once I get upto 390rwkw
Thanks!
