Title: what size Holley jet to use as a oil restricter
Post by: jholmes217 on February 01, 2015, 02:46:22 PM

What size Holley jet should I use for oil restriction in iron 428 Cobra Jet heads using a flat tappet hydraulic cam?  I am using Precision Oil Pumps roller tip rockers and stands with the stock oil return tins.

I use #70 jets for that, but I know that some people use up to #90.

Thanks Jay.  I see now where it says that in your book when you were describing the dyno mules.
