Edelbrock Pro Flow 4
I’m curious about your comment about the FiTech disaster as I have a new-in-the-box basic FiTech unit I hope to use on my 273 going in my 65
I purchased FiTech when they first came out. I wasn’t new to retrofitting efi as I was a DFI dealer in the 90s and even made a stand alone efi kit from a TBI Tahoe setup for a buddies 72 Monte.
That said, the benefits of a good efi system far outweigh carbs. The lack smell, clean oil, mileage, starting and torque being the most obvious.
I used the 600hp NA kit. I used an in tank Walbro pump that draws 11 amps and is a super popular pump.
FiTech decided to use very under gauged wire in a single Deutch connector. This was the first problem as it didn’t take long to melt down. Subsequent units separated the battery feed and fuel pump supply using larger gauge wire and high current handling connections.
Once you got through figuring that out, I had already done this with Weatherpack connectors.
They next issue created a dangerous situation occurred on a customers car and my own. The tach driver failed. This takes the signal from the coil for RPM signal. Without a signal, the system can’t start. The customer car was on a test drive in a suburban area, not terrible. My failure happened on the track at Lime Rock. Luckily I wasn’t hit and I was able to run off the track safely. It’s that event by itself that will prevent me from EVER buying anything from them. They took both systems back and repaired under warranty. Even mine that had the wiring mod done was taken back and wiring harness updated. I can go into other instances but I won’t. I think it’s obvious these systems were a great idea and pushed to EFI retrofit market forward. However, when their systems came out they were HALF the price of comparable systems. Just my .02!
