So Ive owned this car since my junior year of high school, 1983. Bought it for $1650 with money from my paper route the day I turned 16. Its a real 136, 1966 SS convertible 396, 4spd and 4:10 posi twelve bolt rear end. Its had numerous motors over the years from a 396, 427 and now with a 454 (its never had the original engine or trans). Its had a solid lifter, hydraulic and roller hydraulic cams, Holley double pumper, vac sec Holley and quadrate carbs over the years; dual and single plane manifolds, I've run just about everything on this car except forced induction or nitrous. Replaced the manual steering and manual drum brakes with power steering and 4-wheel corvette brakes with a hydro boost about 15 years ago and thought that was the single most impressive upgrade I've done to the car.
Started following EFI over the last couple years, but never thought Id pull the trigger, pretty good at tuning Holley's. Just couldn't resist the temptation any longer for EFI , needed a spring project. So bought a Holley sniper with Hyperspark, Holley billet fuel filter/regulator and a complete Aeromotive fuel tank/pump. Took a couple of weeks working on it here and there installing the system. I was very nervous because wiring is not my thing and there is a lot of wiring to do. Followed the directions to the "T". Powered everything up this morning, programmed the ECU and turned the key. Dam thing started right up and idled! Checked everything over and nothing loose and no leaks. Went out for the trial drive. All I can say is WOW! this set up is amazing, still in learning mode, but dam it ran good for the first time! Better than any set up I've ever had in this car. Only drove for about 30 minutes. Id say it has never run this good before ever! Maybe my 30+ years of Holley carb tuning wasn't as good as I thought, but the EFI and Hyperspark ran so smooth, acceleration was smooth and consistent and it idles perfectly. Id have to say its the best couple grand Ive ever spent on this car. Thanks Holley for a great product.
