sbm solid lifters
good used lifters
for 273, 318, 340 and 360 for use with solid flat-tappet cams. i believe they came from a 273, unsure. very lightweight. if you plan on using a mechanical cam and want to avoid lifter failure, you need these. they were produced back when lifter damage was almost unheard of. asking 100 us$ plus shipping. they are easily worth triple that money. make a reasonnable offer if you feel my price is too high .
