Warrior piston in a Bigbear 400???

[atl3128]

I was wondering if a hi comp piston from a Wolverine/warrior 350 will fit on a big bear 400 (386cc)

I believe they will, as far as I know the bigbear only has a longer rod and cylinder keeping the compression height the same as a warrior, the longer rod may effect compression a little to the higher side though which is good considering the bigbear has a dished piston and about only 8.6:1 compression.
