Cam specs are TSP 220/581/112. Its a little big for a 4.8 even with a 3200 stall it could use a 3600 or a 4000 stall because it starts to really shine at about 3800 rpm.

Do you have any driving vids with muffler on it?

Not a fan of the XL models. They are not true straight thru flow.

I bought it for $30, brand new so no worries. This one is straight through, ill take a pic tomarrow but its just the round one.
