Something in the 210-220intake/ 216-224exhaust would be good for a street driver, if it were me I would stay on the lower end of that spectrum if you are planning on running stock 4.8 heads...also if carbed (which I assume lol) you want like a 110-11lsa, with those durations and lsa you probably looking around .550-.570" of lift, again not tying to over cam the motor due to the stock heads...but you can def make some power with a small cube 4.8 that's for sure, the stock cam does t due it any favors due to the lower peak hp/tq rpm...

Like above mentioned, but what size converter?

Since your new at LS engines and looking for a cam, you'll need to make sure the cam will work with your engine. A gen III cam will work in a GENIV motor, but a GENIV only cam will not work in a GEN III motor. I learned this the hard way.

A gen III cam has a reluctor wheel at the back of the cam and the cam sensor is in the rear of the motor.

A genIV only cam will not have the reluctor wheel at the back of the cam.

The 4.8 is from a 03 gmc savana van, I'll be using a 2000 stall

More converter would be great, but the edelbrock 2215 cam would work great I think.

I have the same motor also in my setup i went for a custom cam.I told the gentle that worked at the custom cam place the type of cam i wanted and my power goal.which is around 350 - 370 hp from the little 4.8.well he told me that its possible,in my setup i will be using a s 2200 stall torque convertor.the spec for my setup is 228 in-224 ext at 0.50

275 in- 277 ext lope seperation 114 and 564 int 566 ex

hope this helps

Too much LSA.

Hey zone did you notice a difference in throttle response when using the lower lsa cam? That is assuming the carb is tuned up correct on both cams (stock 114-119, lower 109-112)

Oh yes, the tighter LSA was way more aggressive down low, the 114 was not nearly as rapid when you stabbed the throttle.
