Damn, you have the 1-1/2" thread? I guess all of the cross reference places are wrong. I believe we ran those in the race boat. It was a pain finding filters for the non-standard BBC filter head. I believe we ran a Fram filter. I'll see if there are some still laying around.

Ive seen some Baldwin filters go down to 9.8 micron...
Just wondering why you want to go so small? |

performance engineering did my motors and said not to use the racing filters as they were meant to be changed say after every race in a car car. ive tried both and never noticed any pressure changes so why not go with the better filtration?
now i'm really confused....... Everyone has opinions, mine is, I like better filtration but with a high volume oil pump its moving a lot of oil. Reducing the particle size may reduce flow (don't know). Going smaller may need to use 2 filters in parallel to keep the flow up |

After doing a bunch of research the Fram HP6A seems to be the best filter for the bigger 1.5"-12 filter threads. 20 micron rating, 20 psi relief valve with a screen, thicker metal. The standard filter by Fram is low quality cardboard, however this one seems to be built he best.

I use the Donaldson P550832 from Amsoil. It has the flow of the racing filters and super fine filtration, the best of both worlds.

That has the standard chevy thread size, no ?

Saw another post on FB that compared micron rating, flow rate and pressure from an episode of Engine Masters where they tested a bunch of them. I used to run the Wix Racing 51222R and switched to the K&N HP-5001.
