I'm probably over thinking this but I have my cam selection narrowed to two.
maybe their completely wrong for my application but they are budget friendly and seem like the specs are decent for a single turbo 4.8.
the first on is a 216/220 with .560/.560 with 114 lsa
second 220/224 .575/.575 112 lsa.
I'm obviously looking for good power and a good idle quality without being too aggressive. i just dont know enough about cam specs in relation to boost and what equates more power while also effecting driveability on the street since this is mainly a street car.
thanks for your input

Although details are rather sparse....either stock or the first one.

First thing that needs to be known is what turbo, compressor wheel, turbine, and turbine housing is being used? Intake manifold and heads? Trans, converter(if used), rear gear, tire size and race weight? I take it that it is a stock bottom end 4.8 as well?

Those are the basic questions that will help you decide what camshaft is best for your application, although the first cam tends to trend more towards what is seen normally in this kind of application.

the turbo is a 67mm ball bearing on 3 turbo. i realize its small but it was free.
stock heads with pac1218 springs. stock intake and yes stock bottom end.
gear ration right now is 4.56, through a 4l80 stock converter for now, car is a 1983 camaro, so weight is 32-3400 lbs if i had to guess

I would personally recommend a 216/220 .578/.569 114+2. So it looks like your 216/220 114 cam is right on the money.

That's awesome. Thanks so much.
any idea as to what kind of power I can expect with that combo (ballpark) with the right tune and fuel system obviously

I would expect that turbo to max out around 600hp on a SBE 4.8.
