I'm looking for the "upper" (plastic portion) of the oil pump stub shaft under the intake (where a regular distributor would go on a GEN 1 small block).........I'm in the middle of doing another cam swap on my car, and (which is fairly common) I noticed a small crack around the single bolt hole that's on it.......I thought about using some Hi-Temp epoxy (which I'm sure would be fine for the application), or getting one of those $150 Heron Performance billet units, but I'd just assume replace it with the factory piece for right now and go "real easy" on the torque, and use a good amount of red loctite....then at a later date, I'll have my machinest CNC me something similar to the heron performance unit for a much more fair price(IMO)..........Part numbers would be greatly appreciated..........thanks in advance...........PS here's a pic online http://www.popularhotrodding.com/eng.../photo_17.html Joe

Do a search on oil pumps shaft lot of info on this subject. I have replace 5 of theses shafts finally made a plate for the top to hold it down and support it . uses jd weld to hold it in place has work for 3yrs. Also check the gear on the bottom of the shaft for wear . I had a hv pump in it before it kill the gear. when to stock pump no prolbems after that. good luck!

 

Thanks guys......Thanks for the part #, I'll just order one up from the GM link.....and as mentioned, later on when I have more time, I'll have my buddy fab something up on one of his 5 axis Haas CNC's (either a whole unit like the One Herron sells, or a cap type like I hear Moore Performance had).....if we go with a cap design, maybe I'll have him run off a few hundred, and make it a REAL cheap option for the LT1 crowd.........I'll keep ya posted.................thanks again..........Joe
