Fuel system for a ZZ383
After running BSP in SCCA solo for 10 years in my C-3 I'm ready for a change and because I couldn't find a buyer for my car maybe I need a bigger motor!!!
I'm looking at a ZZ383 with 449 ft lbs torque and 425 hp. I'm assuming my beloved Quadrajet won't be enough carb. Also will a mechanical fuel pump stay up with it and will my stock fuel lines be able to deliver all that gas?

I just put a ZZ383 in mine and so far the stock fuel lines seem to be up to the task. I'm not sure what the gallons per hour rate needs to be but I would venture a guess that over 80 gallons per hour is sufficient.

I used the zz383 shortblock for my engine build. Fuel delivery is a Holley Pump 80gpm, made up an 8an fuel line to a demon 750 Carb.
the setup Looks similar to 8car's above, except I put a inline filter AN- type between pump and carb. Those are great pics , its the way to do it IMO, almost Eliminates the possibilities of Murhy's law fuel Leaks .

The Quadrajet is plenty of carb and a mechanical fuel pump is capable of a lot more than you need. Carter, Holley, & Barry Grant all sell a pump rated at 170+ gph & it doesnt need a regulator.

That engine is a real nice power upgrade for your car. Many are using it in their Camaros as well.
Edit : If your interested, Nows the time to research new elec. fan cooling system , higher amp alternator, and starter motor.

Sounds like an easy wwap. It will put my car into Street Mod 2 in SCCA AutoX. I have dual fan cooling system that works great, might change to an aluminum radiator to save weight. I also have the smaller new style Delco starter. There isn't much that hasn't been done to this car. Going from 300 ftlbs to 450 ftlbs ought to be fun.
