well now that i got some cash to spend on my bike what would be a better mod a set of cam or a good p&p?

578 motor gets my vote

 

yea i was look at da 558 from hp and da 578 from nicholas and also da 600 stroker from falcon which one would be better for drag bike?

 

the nicholas cycle motors are the best (and by the way, its The, not Da)

 

If your serious at all about draging e-mail Doug @ nicholas asap. Hes' the man when it comes to full blow race predator motors. If you want somthing safe reliable to just wax your buddy then look at our 600 bolt on kits. www.speedwerx.com

 

yea just to beat some 450s at the drag strip and some buddies....... on the stroker kits do you have to use race gas? only if you get high comp. piston right? cause i dont want to have to run race gas

 

im pretty sure race gas is only neccisary when useing a 13:1 or higher compression piston. 12:1 is 98 octane

 

12.1 below is ok to use pump gas? does nicholas offer a 12.1 piston for there 578 kit? also how reliable is the 578?

 

Our 600 kit is not a stroker its a top end kit cyl. gaskets, piston 11:1 or 12.5:1. It is 100% reliable probably better than stock due to billet cyl. and design of cyl. sleeve.

 

yea i've seen your guys 600 bore kit you guys offer it both race gas or pump gas right? is there any performance difference? also have you guys dynoed the 600 kit?
