It's that time again

[TYTILIDIE]

Yep, time to pull the motor again. Can't keep oil pressure up so next weekend I plan on pulling the motor out. When I had this one machined the shop told me they gave racing tolerances. They failed to tell me that would require a high volume pump. Are there any benefits to this? Seems to me it wouldn't last as long. What tolerances should I ask for? Also, does anyone know the intake gaskets that are black and have a white silicon-like seal on them for the intake ports and water passages? They came on my Vortecs but I tossed them without seeing what they were. They looked pretty stout so I thought I would try them out.

Re: It's that time again

you shoudn't/don't need a HV pump. all you need is a high pressure pump.
one bc our sump is so small a HV pump can empty it under sustained WOT.
two you shouldnt need a hv pump just to keep up with cleanaces that are so big that you cant keep oil pressure.
three--- find another shop to machine your block crank and rods properly and with proper clearances.
