84mm Bore

[brentR]

So correct me if im wrong - i just bore out my 701 61x to 84mm bore... i have to run a 760 dome and a 760 84mm pro-x piston?

 

[Big Kahuna]

yes.

Dont forget that the stock sleeves get thin at 84mm. Some builders will say not to run 84mm on a 61x with stock sleeves.

whats the worst that can happen? lolz
if I did 83mm i would have to run the same domes but with 83mm pistons right?

I think so....but dont quote me on that.......

Dont forget to make the ports bigger as the 701 set up is to small for the 84mm bore.
Yes you need to use 760 domes and pistons.

No, aftermarket 701 domes and even the stock 701 head are good up to 83mm. Just check squish.
