Pontiac Timing Cover-8 Bolt 326, 350, 400, 421, 428 1964-1968 BPI-TC-68

68' style timing cover made for later model 4 bolt balancers but will work with 64-67' style 6 bolt balancers but spacing from timing marks to damper hub may be greater than stock.

Has the dimple for Tri-Power intake manifolds.

Logo removed for closer to stock look


Has 0-6-12 deg. Timing Tab

Comes with seal installed and heater nipple drilled.

Not exact stock reproduction. Some fitting may be required to properly fit water pump plates.

Not machined for alignment sleeves.

To install we remove the dowels from the block and then just put the timing cover up and "snug" the bolts. We then slip on the harmonic balancer just enough to engage it into the timing cover seal and see if it's centered. If it's not centered, we slightly loosen the bolts and reposition the timing cover until the seal is centered on the balancer.


****THERE IS NO COUNTER-BORE IN THIS PART FOR THE ALIGNMENTS SLEEVES. COMES WITH FRONT SEAL. THE DIVIDER PLATE MAY NEED TO BE GROUND DOWN ABOUT 1/16" TO ALLOW PLATE TO FIT CORRECTLY. HAS 69 AND UP TIMING MARK. RESTRICTED FLOW HEATER HOSE NIPPLE AND INTAKE PORT. PLEASE REFER TO PICTURE FOR DIFFERENCES TO ORIGINAL. ONE CUSTOMER SAYS THE OIL PAN BOLT HOLES NEEDED TO BE OVALED OUT A LITTLE TO LINE UP WITH BOTTOM BOLT HOLES ON COVER. QUALITY IS FAIR TO GOOD.****
