Kedso, this stuff is real tetraethyl lead just like the stuff in gas when your 427 was new.I use it in my vintage cycles it really works.I have no experience with the off the shelf boosters.A guy had a bunch of it last year, may be too expensive for use in a thirsty V-8 though.If you are interested,email me, I can give you his phone number Kedso, this stuff is real tetraethyl lead just like the stuff in gas when your 427 was new.I use it in my vintage cycles it really works.I have no experience with the off the shelf boosters.A guy had a bunch of it last year, may be too expensive for use in a thirsty V-8 though.If you are interested,email me, I can give you his phone number.
