It could be lots of things. Retorque your valve covers and intake manifold bolts (in sequence) wipe everything down and run it. If you still can't pinpoint it put in some dye tracer and use a UV light to pinpoint the origin. Autozone sells those little Uv lights for a few bucks.

Those are the four hot spots for small blocks to leak, check them all. Might have to get in the tighter areas with a small mirror and light. Also see Viles advice.

I second everything everyone here has said..my motor leaks an obscene amount..I've confirmed leaks in the rear main, pan gasket front and rear, V/C gaskets (even retorqued), and intake manifold gaskets (also retorqued, still leaks there)..My transmission also leaks fluid from the rear seal (and the fluid slowly runs down the drive shaft and scatters on the undercarriage)... I've got so much petroleum based liquid on the undercarriage of my truck I shouldn't have to worry about floorpan or bed floor rust for the next decade, or until I swap motors and degrease everything.  ::)

You forgot to mention whether your power steering pump/lines leak---why stop with oil and tranny fluid?  ;D

Actually, my PS lines are wet around the clamps, but I check the fluid every time I change the oil..well..every time I change the filter and refill the oil anyway..the oil leaks fast enough to change itself atleast once before the next scheduled oil change..and I've never had to add any fluid  ;D
