anyone running a aftermarket EFI system on a Olds 455. trying determine if there is any benefit for daily driver vs a carburetor.
A lot have had issues with the FI Tech, Fleming442 has had multiple sensors and an injector fail on his 67 442. I talked to Mark as he was doing two Holley Sniper Olds builds. The Holley Sniper has an extremely slow and inaccurate wideband. Mark told a Holley rep at PRI about this issue. Their answer, what do you expect for $1000? You get what you pay for, unfortunately. I also would not do an inline pump, do an in tank pump, if you go this route. Good luck.
I installed a Holley Super Sniper (I wanted the extra inputs to monitor oil and fuel psi) on my car 2 years ago and I love it!
I have installed about a dozen of these systems on customers rides. The most radical was a 455 Pontiac, roller cam, aluminum heads 600+HP.
