The Flash Says: "The meat and potatoes of building a Caddy motor are the rods and pistons you put in 'em . . . Everything else is gravy. There's no excuse to build a marginal motor just to see if it'll work. Put the good stuff in your motor right from the get-go!"

Harmonic Dampers
Innovators West Damper (SFI Certified) $call
Billet aluminum construction, viscous (fluid) type damper.
Includes steel crank hub. Will not clear most pulleys due to the large diameter, but will not affect pulley spacing on those that will fit. Requires countersinking bottom timing cover bolts, etc.
BHJ Elastomer Damper (SFI Certified) $575
Billet steel construction, elastomer (rubber insert) type damper.
Can be installed on stock crank hubs (hub not included). Clears most pulleys, but used with stock hub, will space crank pulley out slightly. If you will be running V-belt pulleys, we recommend either back cutting the crank pulley (billet aluminum and cast iron pulleys only) or using the offset aftermarket steel crank hub (sold separately) to correct the pulley spacing.
Some early pulleys from engines with factory dampers are already offset to allow for a damper.
Billet Steel Elastomer Damper (not certified) $390
Includes hub. Details will be posted on the website as soon we have time.
Steel Elastomer Street Damper (not certified) $240
Includes hub. Details will be posted on the website as soon we have time.
Billet Steel Crank Hub $180
Dual keyway. Offset pulley mounting flange to allow for correct pulley alignment with BHJ damper.
Spacer available for correct pulley spacing without damper.
Crank Hub Bolt Kit $15
Helps keep the hub tight to prevent timing gear walking/ keyway damage. Clears all pulleys.
Crank Scrapers $55
Mounts between oil pan and block. close tolerance to rotating parts to wipe off excess oil.
May require minor clearancing depending on rotating part selection.
Main Girdles $165
Steel main girdle to connect the main caps and add strength and rigidity.
Recommended for high RPM (over 6000 RPM), stroker, and power adder applications.
