My 65 Satellite has a 413 bored out to 426 CI. Street Wedge, rebuilt with hardened seats, etc. What would you choose for a new oil filter, and oil too?

Nice looking. You need to post some more pictures. You will get a hundred answers but I like WIX filters and I select a multi-grade, non-synthetic oil that is thick enough to give me 20 psi oil pressure at hot idle in hot weather. For me that may be Driven 10W-30, Driven 20W-50 or Rotella 15W-40. No use going to a thicker oil than you need as it won’t flow as well on cold start up, won’t splash as well at idle, and in general won’t provide any better protection except possibly under hard racing conditions. I also think synthetics are a waste on old cars unless you plan on running 8-10,000 miles between oil changes. But a lot of guys will disagree with that.
Wix 51515 with Valvoline VR-1 in either 10W-30 or 20W-50.
10-30 is plenty good, for any street motor, unless you have lots of bearing clearance
I run Castol 20W40 in the 440 in my 1967 R/T. The engine was rebuilt about 35 years ago, and now has 70,000 miles on it. I add a container of GM Engine Oil Supplement (EOS) at each oil change for protection of my cam/lifters. I recently had major troubles with Fram filters with the 440 in my '64 Polara, so I am all done with them, and now use Wix.
