Everything in the system will except for the exhaust systems, which would take some modifications to account for the longer wheelbase.

Do you plan on making a exhaust system for the lwb and suburban chassis ? The only diffirence is 12" under the cab and 8" behind the wheels. I am glad this was mentioned as the part number does not specify lwb or swb simply c 10 trucks.

Thanks for pointing out the lack of clarity on the product descriptions; I’ll notify the product manager and get it taken care of. As far as for bolt-on coverage of the long wheelbase trucks themselves, I don’t see anything happening in that regard as they were ignored in the Squarebody C10 application, so I see the same thing happening here. I adapted one of those systems to my 1979 C20 rather easily and I’m sure others will do the same with long beds in this application.

Just to confirm this is the correct part number for installing a 6L80E in my 69 C10? The website indicated it was only for the T56 transmission.

I just recently purchased a 2010 Camaro SS and going to start the process of stripping it down to be the donor car for my '69 Step-side. I want to reuse as much of this car as possible and it looks like this LS swap system is the direction I want to go to bolt it in. Just not sure if I can keep the Camaro oil pan or if I need to buy the Holley 302-2 or 302-3 while I'm at it.

Thanks,
Trent

Trent, the base crossmember is the same for all the transmissions with their specific geometries addressed by the use of spacer blocks, as needed. The T56 mounts directly on the center beam as its mount pad elevation is the lowest of all the transmissions. I believe there will be more crossmember part numbers being released over the next few weeks to cover the other transmissions. I can’t say one way or the other if the stock oil pan on your engine will be compatible with the Hooker Blackheart engine mounting brackets, but my guess is it won’t be based on my experience.

Hey Trent. The stock oil pan on the 2014 and up truck L83 will not work without modifications to either the cross member or the oil pan. It's about 4 or 5 inches taller than the swap pan from Holley. I tried to make my L83 fit in my 72 C10 and quickly came to that realization. The motor would be too far back in the chassis if I allowed a safe oil pan ground clearance and wouldn't fit under the hood if I placed it over the cross member. The only solution my pea brain could muster was to clearance the cross member. It was quite the hack so I added all kinds of structure to the inside of the cross member before I closed it up. If I had waited longer it sure would have made it a lot easier.

Thanks for the responses guys. I think i'll just order the Holley pan while i'm ordering the swap brackets. I'd like to use the camaro pan so I can keep the factory engine sealed up but guess its not in the cards. Guess the benefit will be not having to buy 8 quarts of oil to fill the new pan up, like the stock camaro pan.

Looks like Holley has some trans spacers for other kits for the 6L80E so I may just buy a one of the others and some shims to temporary get to 11/16" in height. I'm sure the actual spacer will be released before I get all the wiring and plumbing done and ready for a test drive again.
