Mastodon Small Block Chevy V8 Hydraulic Roller Lifters & Link Bar

Set of 16 hydraulic roller lifters with link bars — the retro-fit conversion that lets you run a hydraulic roller camshaft in a Small Block Chevy that came factory with a flat-tappet cam. Hydraulic rollers reduce friction, allow more aggressive cam profiles, and don't need the zinc/phosphorus break-in cam oil that flat-tappets demand.

Link bars keep paired lifters synchronised to prevent them rotating in their bores — required for flat-tappet blocks that don't have the OEM lifter-tray feature.

Specifications:

• Application: Small Block Chevy 265 / 327 / 350 / 400 (V8) — flat-tappet block retro-fit
• Type: Hydraulic roller, retro-fit with link bars
• Quantity: 16 (full V8 set — 8 pairs)
• Lifter OD: 0.842" (standard SBC)

Install note: hydraulic roller lifters typically require different (shorter) pushrods than flat-tappet — measure and order pushrods to match.
