Hello everyone, I wanted to introduce myself as a new member and long-time lurker of the site. I finally purchased my project car — a 1974 260z. The car came with a lot of extra parts from the previous owner, so I’m excited to start going through everything and planning the build.

I’m currently sorting through all the parts. My first plan is to get it running again. The previous owner said it was running before it was parked, although I can’t remember if he said it’s been sitting for 2 years or 2 months since it last ran. Either way, I’m looking forward to bringing it back to life.

The previous owner also stated the engine was rebuilt about 8 years ago and that he seldom drove it — probably around 500 miles after the rebuild. He mentioned it has a 4-barrel Holley carburetor. In his notes he wrote: 4776-2 650 CFM double pumper. From my research, that seems a little too big for the engine. I see a lot of recommendations for the SU round-top carburetors, but I haven’t decided what my long-term plans are yet. Since he was able to get it running with the Holley setup, my plan for now is to try getting it going as-is.

Does anyone have experience running a Holley setup like this on a 260z? Can it run properly with this carb?

I recently read beg3yrs’ post, and it was really motivating to see the progress and dedication. Looking forward to learning from everyone here and sharing updates on the project along the way.
