I need to change out Rear Main seal, so as long as I'm going in I want to upgrade stock oil pump in it to a 60 lb. High pressure/volume set up in my '69 GTO WT 400.
Have built up #48
heads w/stainless valves & higher pressure springs & new cam w/Roller Rockers.
Looking for recommendation for brand & model to buy?
I see Standard volume/High Pressure pumps are generally available... ?
Is this the same, or does it need to be High Volume & High Pressure pump to match the original equipment set up w/RA III engines as originally built?
I have seen the posted recommendation for the Butler 60 Lb. pump at $160, but it sounds pretty spendy and I'm thinking they are probably not the only game for this?
Also been reading about hardened shaft... want to buy that too & I need make & model recommendation for that too?
And 3/4 pick up?
Have '69 Pontiac Service manual and says need to run Cadmium plated Distributor shaft gear too when running higher pressure oil pump?
Need a brand & model for that too?
What about a replacement oil pump spring?
? - Can my stock pump be modified to increase it's pressure to 60 Lb.?
I need to order up all the parts as I'm looking to pull the motor and do all the work ASAP, so was hoping to order the parts sooner than later.
I'm seeing some recommendations for better gaskets and RM seals and have the info from those posts, so I am good there.
Looking for this request to get all the info to process to make informed purchase to end up w/60 Lb. pump w/Hardened shaft, hopefully w/o spending $160 w/Butler.
If I have to I will, but have to be able to match the higher performance OEM pump set up?
Any info would be very much appreciated to help me with this info request.
You guys are great !!
Thanks so much for all the advice and recommendations so far.
