how much????

[twisted300ex]

see im rlly getting into racing my 300ex and i was wondering if anybody would know how much it would be to send my motor to sparks and have them do as much as than can without going over 300cc

[honda300EXtreme]

my guess would be around 800,, probably a little less,,

you spend a lot of money in head work.. port & polish, oversized valves (+2mm), a cam, hd valve springs, hardweld rockers, your looking at around 600 bucks right there...

then the piston - 120 or so,

and top end gasket kit - not sure on price probably around 50...

and then you would have a well built 300 engine...

but i would just send them your head.. alot of the work you can do your self...
