I placed an order for my system a few nights ago and I'm eagerly awaiting its arrival.
I think this kit would greatly improve the SL6's manners with any intake, clifford, Aussie, Offy, better atomization and adjusting on the fly if you begin wetting her down.
Distributors are just as plentiful for the SL6 as the SBM, and with the internal timing, you just lock it out, so no tinkering with springs and vacuum.
I'm thinking it will be money well spent.
