Default 1971 -149 moving foward

you may not be in trouble ,first move that nest out ,you have no cooling ,but you know that ,next have a good machinist [mic] the bore and piston ,,check the top of piston ,to see if it was over size ,,the only way to check the end gap is remove the rings and place them in the bore ,but you will take a chance and brake them ,so you can do it this way ,and use a hose clamp .place around piston ,and pull up on clamp ,leaving room to see gap .shouls be in the range of .018 .and the gaps should be 180 degrees apart .from each outher .and not in line with the rist pin .or the rubbing area of the piston .the bore should be in the range of .0045 to .006 .and have the machinist check for taper .i think you will fine your [OK] hope this helps ,David
