400 to 416 difference

[jeremy_283]

if all I do is change my bore from 400 to 416 on my ex will i really notice any power differences?

i went with a ross racing 10.8:1 piston (416) and a hotcam stage 2. Along w/ my other mods it made a huge difference in power, and didnt cost very much either, i would definitely recommend it. Also i have had no problems what so ever with it and the engine's been together for close to 2 years now. the only thing i have done so far was re-ring the piston and hone the cylinder. i would definitely recommend a gt thunder rev box and if you dont have an aftermarket intake system i would recommend that also to see full potential.

the piston alone won't give a huge gain. if you combine that will a cam and a good full pipe then the gains are well worth it.
