This whole time of building my SBZ (75 280z w/ SBC 350), Ive planned on running the Holley Street Avenger 670CFM carburetor. But I had a friend talk me into thinking about an EFI system, specifically the FiTech GO EFI 4. Ive been doing quite a bit of research, and it looks like a great product with a lot of benefits. My question is, has anyone on here used it, or anything like it, and are there any major complications I need to be aware of before I bite the bullet. Any info would be much appreciated. Thank you.
