Pop the hood and count the valve cover bolts
5 per side is and LA, 10 is a magnum
And 4 bolts right down the middle means some dummy dropped in an LS1 :poke:
:) 5 Per side so it's an LA. Cool. I ordered up the felpro gasket kit, looking at the old pan looks like the 1 piece had shifted all around some parts of it were way in the pan. I also have the cork so can decide which one to use. I like that PCV valve that looks cool.
