Lol, I'm just an old guy who began building racers in the '60s. Glad you have the correct wires. That keeps down the list of problems that can occur. Yes, I use the BKR6E plugs on the street. They burn clean and last very well, even with lead foot driving, as long as the timing and F/A is correctly set. I tuned for 86 octane pump gas and have no problem with them. But, I sometimes bump the ECU settings and run higher octane. The TA is a House of Kolor Shimrin dark cherry color. It was originally a factory cinnamon color. The '87 SS is also one I like. I once had a brand new white '86 LS Monte Carlo - same SS front-end from the factory (great car). I would still have it, but it was completely totaled in a wreck. I'm running EZ EFI 2.0 throttle body systems in two vehicles. Plan to use XFI systems on some more cars in my collection. The Turbo 200R4 is a great transmission when built for the pressure of high horsepower and torque. My '86 LS came with the 200R4, and I kept it. I had it built by Fairbanks years ago, and have a customized '56 Buick Special it is going into. The car looks like one Broderick Crawford drove in Highway Patrol - definitely not grandpa's Buick with its 468 horsepower mouse motor. Sounds like you got the TV set right. But, I haven't used that throttle body.
