They measure 375cc

Liner hasn't been replaced as looks off centre and wafer thin at the front

The giveaway is not cut down either like 370 conversions

They may be Barlow tuned but at 2.5mm over using ypvs pistons I would only use for relining as the thin uneven liner concerns me

Yep the liner is definitely thin would it be ok for drag racing? Hard quick use? I wouldn't want to risk it on the road for sure🤞🤞🤞🙄

May be usable for drag

2.5 is usually considered the absolute max

The uneven liner can cause uneven heat dispersal but on a ragged for 10-15 second thrash it won't have much chance lol
