I put mine here, pretty well hidden behind the seats.

Good idea to call Summit racing. The small converters are generally higher stall. Picking torque converters is something I leave to experts. For my car, I called TCI, and they needed my cam card, the weight of the car, and the rear axle ratio. There is a lot more science to picking them than you would think. You should call your torque converter supplier and chat with them about your application.

I purchased a Grams Wideband 02 sensor to help me tune my Holley HP 750 carb. It came with Bosh 17025 5 wire LSU 4.9 heated sensor. My JBA H pipe has a pair of 02 sensor bungs installed as you can see in the attached photo between the bell housing and main body of the FMX. A while back I think I read that you can damage a "heated" 02 sensor if you do not power it up when you run the engine. Anyone know if this is true or not? As I only have a single meter, I was hoping to buy a 2nd 02 sensor and have both pigtails in the car and switch back and forth so as not to have to crawl under the car and move the sensor back and forth to sample each bank. Yea, now I see there are gauges that have two sensor inputs, but that was after I purchased this one, and they are also a bit more pricey than the $150 that I paid for my Grams kit. Grams also seems to be a respected brand. Assembly update, ignore the LED lights hanging below the valance. Power Assist control valve and power ram. What a PITA the hoses were to install.

yes, there is a difference in the distance from pivot point to booster/mc rod. The distance is 5 inches on a power pedal and 2 inches on a manual pedal.
