I have a 600hp mast motorsports LS3 with a T56 and a 6932-07 MCLEOD TWIN DISK CLUTCH ASSEMBLY <1000HP and it's pretty stiff. The clutch leaked because it took over a year to get into action however since then no issue.

Thanks for all the comments. That what I needed to make a decision. May well do the light flywheel while it's apart. Always been a fan of those on big block cars.
