Project LS NOVA

Hi Everyone,


I've read through a lot of posts here and there is some amazing information.


I'm hoping to get some direction/input on where I'm at on my build.


I have a 1971 Nova that I have the Speedtech Performance Pro Touring complete kit. I also have a a Chevy Performance connect and cruise LS376/525 with a T 56 Magnum transmission. The Nova has a 1969 Camaro dash assembly installed and I'm working on planning out the dash bezel and gauges. I've seen a lot of people use the Nova dash pad on the Camaro dash assembly and that is my goal.


My hiccup is figuring out what dash bezel to use. I was thinking of using the Dakota Digital HDX (or RTX) gauge kit with the console but I would have to purchase the dash bezel that either has the Camaro badging or put in the clock in the middle of the speedo and tach. I didn't really consider the Holley 12.3 dash since the whole connect and cruise kit was complete but I like the way options for the 12.3 dash bezel, which would remove the concern regarding the clock/Camaro badging.


If I go with the Holley 12.3 dash, will I have any issues with the connect and cruise? Am I replacing parts on the connect and cruise or will the Holley work with the system? I'm mechanically inclined but tuning is an area that I haven't adventured into at this point.


I see a lot of posts about the pros of the Holley if I want to add a supercharger in the future but I'm trying to figure out compatibility issues/concerns with using the Holley system?


Anyone done anything like this before that can help point me in the right direction or have any suggestions?
