All my friends that have rode 400's before say this one is very strong for a 400. We got it up to 63mph yesterday. Is this a typical top speed. It also wants to pull the wheels of the ground through 3rd gear if you race it. Is there a way I can tell if there is any engine work done other than opening it up and looking.

I have no doubt I have 426 10.1 with stage 2 hot cam with kibble white valve's hd crank hd timing chain and if I put 15 front with my 36 rear I can easily get 80+ now with my 14/37 i can get 73 to 74 really pushing it to get but will do
