with a 440 bigbore kit a whitebros pipe a new rear sprocket new valve springs to go with a new stage 2 hotcam kit and having my400ex jetted and burnin 93 octane fuel...do u think my top speed will be any greater??

 

i would hope so

 

Compared to stock? Um....yes!

 

how fast do u thnk it will go with all the upgrades???

 

it will go as fast as u gear it to go, i'd say you could pull 80 mph if u gear it right

 

Someone just came out with a 460 kit,it comes with piston/rings/sleave/cam and exhaust and they said it makes the power a little more than a 450r

 

realy im goin to have to look into that....do u know wut the price on it is???

 

if i put the 460 it on my 400 how fast do u thnk itl run?

Well with more power you can run taller gearing which will give you more top end. But you can build it all you want, even put nitros on it, and it still won't go any faster. It will just get there faster.

If you build it for more power, raise the rev limiter, and gear it higher you'll get a noticeable top end difference.

By the way, just putting 22's on there with stock gearing you'll get a little more top end.
