Re: doing an ls swap in my 69 c20
It was my understanding that the truck pan would work. It does depend on your motor setback /placement. However, it hangs down several inches below the front cross-member. If you are running stock height or a 4X4 it will not likely be an issue. If you are going low, I wouldn't recommend the lowest part on the underside of your truck be the oil pan.
I used the GM pan sold just for conversions. Comes with the dipstick and windage tray. It's a nice piece. This pan will be close to even or sightly above the lowest part of the cross-member. I will get you a picture later today. |

It worked for me. I modified my own motor mount saddles which brought my engine up about 1" and that made the stock oil pan at the line with crossmember. I have pictures on my build thread.

Many thanks to you both- I'll check ebay. I'm not lowering it- like the high ride.

Re: doing an ls swap in my 69 c20
if your not lowering it, you should be ok with the stock pan if its from a truck. the only issue is it hangs below the front crossmember, which shouldnt be an issue if its not lowered
