I have the LST with the Mach 26 and wa swondering if anyone could HELP ME HERE!!!!Now I hear all over the Mach 26 is like the all round best liked engine? Now I wanted to know if the Novarossi 28 would be faster or stronger then the Mach 26. You know a NOTICABLE diffrence that i will see with it in there? I meanis it worth spedngin the monmey to egt the engine even at that great price? If it is not really gonna impress me as being alot or even noticabley better then the MAch I would rather stick with the Mach? Though a new Mach is almost the same price? So i should just get the Nova? I mena its got be alittle better and or at least equal? Let me know what you guys think? Also i was wondering what the TOUGHEST engine for big blocks is out reight now?
