Currently am gathering parts for an Ls7 swap into my Firebird. Staying dry sump, utilizing the factory style Ls9 oil pump and a longer snout crankshaft. Similar to what was done in the GMPP test car:

According to the article, the only changes that were made in the accessory drive was that a C6 Z06 AC compressor was used, along with an ATI harmonic balancer.

I am assuming that a factory (Fbody) power steering pump and bracket, water pump, alternator and bracket, idler pulley, and tensioner assembly are (or, can be) used on this car for proper configuration and fitment...Please correct me if I’m wrong.

Also, since they used an Ls7 Corvette compressor, this leads me to believe that the ATI balancer is specific to the C6Z, rather than an Fbody. Agree/Disagree?

Lastly, I wasn’t entirely sure if I would need a C6Z compressor bracket, or an Ls1 Fbody one. I am assuming Fbody.

Has anyone made this swap with an Ls7/Ls9 dry sump oiling system?

TIA!

 

 

 

Did you ever figure this out for sure?

 

I didn’t. Ended up just keeping it simple with a wet sump 6.2..

 

Is it possible to add a dry sump oil system from a LS 7 to a 5.7 LS1? at least using all factory parts.

 

Yeah if your going to use the LS7 crank or an LS3 dry sump crank. GM installed an LS7 with dry sump in a 4th Gen car before so yes.

 

The oil pump is thicker front to back and this causes everything to get spaced out further in front of the engine. The extra thickness of parts stack-up requires a longer crank snout.

You will need to look at aftermarket belt driven dry sump if you want to retrofit to an LS1. Or if you're building the engine from scratch then I suppose you could wrangle up a LS7, LS9, LS3 dry sump crank, but I'm not sure if journal sizes are the same between all LS engines And the LS9 will have an 8 bolt flywheel.

The LS7 dampers are unique to the dry sump engines. Everything else is standard Corvette with Corvette pulley spacing. If you want to use f-body accessories with a LS7 Corvette dry sump, then you will have to order a custom damper from ATI for everything to line up properly.
