Jamie Sir I can't see just the 124 pistons, gaskets and barrels set up on your site for a 107.Please excuse me if it's there as I'm an internet gumby. Also I have a set of mint 114 barrels for a core service exchange do you have a rough costing from here in Australia and the return with the big bore kit ?They can be sent and returned in SE packaging boxes if that helps you out, no need for express post just the cheapest both ways. I could bore that set to 120 here but my instincts are to go with you.

Peace to you Sir.

 

We do not currently offer the M8 124/128 kits as a piston/cylinder only kit, we only currently offer them as a complete kit with cam, pushrods, lifters, gaskets, etc.. I expect we will indeed offer piston/cylinder kits at a later date, note these are new cylinders and do not require a core. We do offer 117" big bore for 107" engines and 124" big bore for 114 & 117 engines which include bored cylinders.
