Street or Strip, a Milodon fixed idler gear will make more power than a timing chain or a floating idler gear. It will make the same more power as when new, virtually indefinitely. Even on the street, it is almost impervious to wear. It will keep the same cam timing you set, whether the engine is on the engine stand or at 10,000 rpm. Fixed idler, steel billet gears can not change, unlike all other flexible chain or belt drives.  Chrysler Part # Price 318, 340, 360  Small Block 3 13600 $359 331, 354, 392  Early Hemi 13600 $359 AMC Part # Price 290-401 13700 $375 Buick Part # Price V6 (Stage I & II) 1 13800 $370 V6 (Stage I & II) 1 13805 $365 Pontiac & Olds Part # Price Pontiac 389-455 13900 $355 Oldsmobile, 1976 & Earlier 14000 $419 Ford Part # Price 289-302-351W 2 14100 $345 351C 14200 $355 427 SOHC 14300 $360 390-428 2 14500 $375 429-460 14600 $360 1 = Buick V6 engines requires an aftermarket even fire cam with an odd fire nose to run a gear drive assembly 2 = This engine can NOT run a stock -stock mechanical fuel pump with gear drive.  An electric unit must be used. 3 = This unit can run a stock-style mechanical fuel pump, but the eccentric must be shortened 1/4".
