| − | + | I know this converter was stock, I know it was 1200 RPM flash stall, I know the slippage was the same as my 'bird | |
| − | + | already described above, and I know it drove fine for granny. But I decided to swap it. The B&M gave my combo a | |
| − | + | 1700 RPM flash stall, [b]the launch[/b] felt much better. It felt like I had swapped to a 350, when launching. And | |
| − | + | by launching, I mean flooring the gas the instant the light went from red to green. It pushed me into the seat | |
| − | + | noticeably more, and I loved it. I thought I had invested wisely, and I felt I got what I paid for. | |
| − | + | But I was in for another surprise. I finally stopped playing in traffic and got on the highway. I was so stunned | |
| − | + | to discover my slippage wasn't 200 RPM. It was just 50 RPM! So I stomped the go pedal, the RPM shot up by another | |
| − | + | 350, for a total of 400. | |
| − | + | I didn't bother to check my MPG, this carb was also leaky, and I always did 17 MPG, same as with the 2.41:1 axle | |
| − | + | it had before. But that aside, I know it would help MPG. After all, my previous '78 / LG3 / TH350 / 1200 / 2.41:1 | |
| − | + | / 205-75R14 Camaro did 23 MPG with a best of 26. | |
| − | + | I can't say the 2000-stall drove better than the 1200-stall in the snow, but I can say it wasn't any worse. | |
