416 V.S a high comprssion piston

[hondaboy400ex55]

ok i got a question i was goin do a 416 11-1 compression but then i seen a 11-1 compression stock bore (thats were i wouldent have to bore out the motor right?????) but how big of a difference would there be between a 416ex with stage 2 hotcam V.S a 11-1 compression stock bore piston with a stage two cam??????????????

not a ton of difference. a little more low end power with the 416 probably. both setups will run really well. yes, you would do no boring with the stock bore high compression piston. i would get the cylinder honed out so the rings seat properly though.

you can probably bore up to a 426 from the stock sleeve a bigger bore than that will require a sleeve anyway the more cc,s the more low end youll have , but compression helps a lot there too as well as a decent cam , pipe jetting & open air box & the h.p. will rip far more than stock but the bigger the better I run a high comp. 440 thats yet to be stroked so theres never really enough power when more is possible !
