I just posted a similar ? A few days ago. I am switching to the Holley 4 bbl. The responses I got were that it's a bad idea and you need a fuel pump psi rated for carbs. My thought is that I don't want to take the chance. 100$ isn't a bad insurance policy for a 500$ carb. I think it would work just fine with the bypass regulator I bought but if it does fail you would be sending enough pressure into the carbs to warrant a rebuild x 3. My carb needs 7psi, plan on the 14psi Holley so the regulator does its job and fuel bypasses often to keep the pump cool

The story is the that the po had several cars in various stages of restoration included a pair of 280zs. No progress had been made on any of them in the 2 years I knew him. We made the deal that if I finished his red z I could have the blue one along with whatever parts he had in storage. The red on needed bumpers installed, trim stuff, windshield installed and an efi relay. So for a cpl weeks of after work and weekends putting the red one together and a lot of digging thru various storage areas I got the blue one and a lot of parts including the Toyota 4x4 front brake and 240sx rear brake upgrade and bigger master cylinder

There's a few, works been done since then, hatch glass and windshield in door handles trim etc

I ordered an adjustable regulator advertised from 0 to 60psi w a gauge port, everything else has been ordered except that pump so I'll add it to the list and be sure to install before trying to run anything, hate to destroy the carb first shot. Update on the carb search is one was located on eBay, new in box from someone that purchased for project and decided to rebuild their Weber. Best offer of 350$ shipping included was accepted and its on its way. Only items left now are throttle cable kit, air cleaner and carb Elec fuel pump. All pics are on my phone that died last week, I'll try to pull a few from my fb page and if that doesn't work I'll take some when I get home from work. Also located appliance mesh 14" wheels locally for 100$ to replace the weld racing rims the po had drilled out from 4.25 to 4.5 to make fit

Hey all, fist post on this site, hoping for a little advice on my conversion. Mind is made up so no debate about fuel mixture etcetc necessary. I'm gutting efi on my 77 280z and going to Holley 4bbl 390cfm. I found and purchased Bob sharp racing holley intake manifold. Carb is being ordered next week. The biggest question I have is the fuel delivery. The car has a brand new aftermarket pump for efi, high pressure of course, can I keep this pump and add a bypass style fpr w gauge under hood or do I need to buy a carb low pressure pump and a bypass fpr. I'd hate to not be able to use a brand new pump. Also, any info on the Bob sharp intake, from what I see they have been out of production for a long time and perform well. I pd 200$ for it, 120$ less than a new arizonazcar one. Thanks
