My LZ320-TC1MD is nearly on the way out. I purchased from IPP years ago, it was marketed as the "JWT Severe Duty" which does not correlate to JWT's website. However the part number LZ320-TC1MD is listed as hi-perf. No idea if this is the HD clutch you are talking about. I don't see a "HD" on JWT's website. It has served me well for 8 years or so and ~500whp/tq. It is mostly streetable but can be a touch grabby. I'm not sure if the occasional start from a stop challenge is due to the clutch or the fact that I've deleted the vacuum assist. I'll likely replace with the same, but I'm interested in other alternatives that may be more budget friendly or more streetable.
