Is the timing set on these HiPo's different than your basic 289? Seems to be the case with what came off this engine. The crank gear has a split pin 180 out from the key-way slot and it fits into what I would call either a counter weight or maybe an oil slinger that mounts on the backside of the gear. There is an oil slinger in front of the gear also though so I'm not sure which it is? Also all the cam gears the parts house show have a collar on them where the one that came off the engine is just flat.
Where can I get a correct timing chain and gear set like what came off? As always, any help or leads will be greatly appreciated.
