Boosted,
I have about $160 to spend (approx £100) which is why the LS2 swap seemed favourable. Have looked for LS6 cams, only one I have found so far is $199 so out of budget, but will continue to look.
Understand what you mean about 'plug and play' but with a front cover at $49 (made a mistake earlier on the price) an LS2 cam and yellow springs for $100 and the correct sprocket at $20 I am about where i want to be.
Really appreciate the advice, feel like I have learned something today.
P.
