he had scoops, oversized oil filter, bigger valves, larger pistons, and a bunch of other stuff to lower the temp
Yea i bet the 440 kits biggest problem is that they over heat !!!! to get to 500 your gonna be stroking it and a huge bore !!! CK 1999 is the guy to ask !! on a 450R your runnin a +3 crank and 100mm bore and big time head work comes out to 511 or so !!

Ya the kit came with bigger pistons stroked cam crank and a bunch of other stuff.... oh and so basically bottom line is keepin it from overheating if you can do tht the bore kits in general arent to big of an issue
i like 450s im gonna buy one wen i turn 16.... 400s are my fav though first thing i ever drove..... and yes it might be a stock 450 not sur but the wieght diff is wat would make the 400 quicker... i personally have watched some 450s modded put up against bored stroked 400s and they just dont have near as much take off power... unless uneeded wieght is taken away tht is
