Fits: Small Block and Big Block Chevy & Holden 253, 308

Holden Fitment Note:  For Holden V8 - 253 308 - Red Blue & Black motors. These lifters are taller in the pushrod seat height by 0.065". So you will need to run a shorter pushrod than the "normal" holden V8 by 0.050". We always recommend measuring pushrod geometry and ordering the correct length pushrods due to differences in aftermarket cams, heads, rockers etc.
