This converter is just over two years old and has about 5k miles on it. It took me into the low 11's with low to mid 1.5 60 foot times but has stock like street manors. It has a 3600 RPM stall rating but under normal driving feels stock and it is a lockup just like stock as well. It fits the 4l60e with LT1. Only selling because I went with a 4l80e swap which I bought another Edge racing converter for. New this costs just over $600 with about a two week wait. Asking $395 shipped.
