[fast2007]

Fixing to put in a piston kit,ported head,cam..etc I have heard a 410 makes more HP than a 440 ,due tolighter piston..Anyways lets hear some of your combo's and hear some #'s or info you no to be true..thx in advance..

[AJG400]

i couldn't see it having more power but it would prolly rev faster

what does yours make?Ever run any 450's?anyone else?

a well built 416EX can make HP in the high 30's - low 40's

Mine did about 38 on a dyno earlier this year. I also think there is HP left in mine due to porting, but I don't want to but a new head a open the engine up again.
