port/ polish

[stupid driver]

how much difference (hp/revving) is a port and polish going to make on a 440. im thinking about boring it out, and i want to know if i should port/polish it, or if its a waste of money

it will be worth it but it won't be neck snapping improvment. hetrick racing will port and maybe polish for under 200 dollars if i remember.
