Big Bore Kit

I am considering installing a 686 Big Big Bore Kit onto my Rhino. The install will include a new cam, valve springs, port and polish, Piston, etc. I would like to continue using pump gas. I do have a few questions.
Which is a better Kit to install. The KMS or the Trinity or?
Do I need to upgrade my cooling system?
Is there a shop local to the Los Angeles area that can do the install?
Should I consider a 727cc kit (can I still use pump gas)?
What reliability issues will I have?
Should I install a stroker kit?
What can I expect in HP gains?

I appreciate any input, help, suggestions anyone can give.

Not do a 5mm over 727, you cann't keep it cool!!!
W/ a 686 there is no need for a cooling upgrade.

Call the Pro Shop in Stanton 714-892-1300 they can hook you up w/ everything you need, even a stroker motor if you want. (he built me one and it is no joke)

As far as gain it all depends on how much you want to spend.
Lets just say over 40hp is easy w/ there 686 kit (on there dyno)

good luck
