Good afternoon,
I have a stock 68 340, what type brand oil filter is good and reliable. Engine break in on Wednesday, builder said pick up oil and filter.
Thanks in advance.
Fram PH43 (Short) or PH8A (Long) or their equivalents based on clearance to manifolds or to headers.
A 90° adapter can rotate the filter's orientation to allow for the Long filter to fit.
Consider a WIX filter 51515. Several other quality filters exist as well.
