Product Details

Eliminate chain stretch with Edelbrock Performer-Link True Roller timing chain sets. Edelbrock Performer-Link True Roller timing chain sets are for use with either performance or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets eliminating chain stretch. Crank gears are machined from SAE 1144 stress-proof steel. Most Edelbrock Performer-Link Tru e Roller timing chain sets have three keyways to ensure accurate timing for early or late-model vehicles and to allow you to set cam timing 4 degrees advanced 4 degrees retarded or stock. However 50-state (stock replacement) sets have single keyways. Edelbrock Performer-Link True Roller timing chain sets are not for use above 6 500 rpm.

Accu-Drive gear drives are not recommended for use above 7000 rpm or on computer-controlled vehicles with knock sensors. On some late model engine blocks it will be necessary to check the clearance behind cam gear at the engine block at the 12 oclock position. Make sure the gear clears the oil galley bosses on the block when in the most rearward position. You may have to grind or machine the block for the correct clearance. Will not fit engines with a factory hydraulic roller cam.

This Edelbrock Accu-Drive gear drive won stretch or wear out. It provides up to eight degrees of cam timing adjustment in two degree increments has offset bushings for easy cam indexing and SAE 8620 steel gears that operate at higher rpms. This Accu-Drive will fit under your stock timing cover and has that gear whine sound we all love. Minor machining to the engine block may be required.

The Accu-Drive camshaft gear drive kit replaces a stock timing chain with a precision gear drive system. Just replace the stock crank and camshaft sprockets with Accu-Drive gear and slip in the idler assembly. The Accu-Drive gear drive system transmits power from the crankshaft gear to a full floating main idler which drives the camshaft gear. The unique feature is the ability of the main idler gear to float to an optimum position between the crank - shaft and camshaft gears assuring absolutely equal load sharing between the crankshaft and the camshaft gears.Accurate timing control—no chain to stretch  Smooth camshaft rotation for precise valve control at all rpms  Longer life because of reduced gear stress  Easy installation—does not require any special machining operations  Provides camshaft timing adjustments in two degree increments  Works with stock timing cover  Compatible with all standard camshafts except OEM roller-lifter cams  High quality SAE 8620 carburized gears operate to higher rpm than timing chainsAPPLICATION PART NO.Small Block Chevy 262-400 V8 7890Big Block Chevy 366-454 V8 7891Ford 289-302 V8 351W 7892Ford 5.0L EFI 7893Ford 429 7894Ford 351C  V8 7896Pontiac 7895
