Engine setback discussion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi,

I am working on a 70 SWB with a L83 swap. I have the engine sitting in the frame and it is sitting nicely. I am using a LT4 oil pan to clear the front cross member. Everything is fitting nicely, but I have the engine about 1.5" back from stock and the pan sits ~ 0.5" below the cross member. I plan on fabricating a skid plate for the pan so that is not a worry but I wanted to hear about the pro/con (yes I asked for it) on this install. Don't know how to attach pics to these posts, but there are a few in my members area.

Cheers!

Im going to move this to the Ls section for you. Your way more likely to get some much more specific answers in there.

Why not just swap to a shorter oil pan?

I looked for a different oil pan for the new Gen V engines. The LT4 pan has a much lower profile over the cross member than the L83/L86 oil pan. Moroso is building one for these swaps, but did not have a release date. As I understood it, their pan will be similar to the LT4 pan. So at the time the LT4 seemed to be the best option.

I wouldn't sweat it being only an inch and a half back from stock, that sounds pretty good in my opinion. Also, if the pan is only half an inch below the crossmember, then unless you plan on laying frame, I would be fine with that too.
