I installed the "muscle car" oil pan last night and 2 bolts do not line up. In the picture you can see the hole without a bolt.
The oil pan is this one.http://m.summitracing.com/parts/nal-...FYVAaQodi_YDVA

How far off is it? Did you try loosening all of the other bolts and put a punch or drift in the hole and gently prying it over?

I put the same pan on my LS1.......Not sure why that hole is in the pan, but there is no matching tapped hole in the block at that location....

Yeah, no hole even close.
So, A1971blazer, you had the same thing but no problems with leaks?

It's the same when installing an LS1 pan on a truck block. I had no leak issues.

No leaks.....the LS design cast aluminum pan and gasket is far and away a better seal for the pan than the old school pans ever were.
