and wat is the best engine kit for my 300ex..like the one hetrick racing sells

[hondardr4life]

Micky Dunlap's FST sells a good 330 kit:macho . But If I had to do it all over again I would go with curts sparks 330, because theirs is actually a little bigger than a 330. All the others are an 81mm piston. Sparks' is an 82mm.
