what solid cam is equivalent to a hyd 268 ?

found this article on our site about oil pumps . I bet I was sucking the oil pan dry because this engine took so long to rev up.>>> High pressure requires a stronger intermediate shaft (and sometimes a drive gear change)
High volume can starve the engine for oil at higher RPM's due to pulling the sump dry before the oil can get back down into the pan again.
A standard pump can have not enough flow and pressure for a loose engine.

For a regular performance street motor a standard pump is totally fine.

FYI, Had nothing to do with how long it took to rev up. Did you have a gauge on the engine so you could monitor how much oil pressure you had at 6000 rpm where that big cam needed to run? How many miles on the engine? What were the oil clearances when the engine was built and what were they when you took it apart? Were the bearings down to the copper? If they were the engine was worn out. Have your machine shop clearance it right, forget re-using that cam you have and put in something the little 273 will like and let it go at that. A stock rebuild doesn't need a HP or HV oil pump. It doesn't need to spin a lot of rpm's. Make sure all the internal oil galley plugs are in place.
