WIX 51335 Oil Filter

This the filter that I use on my mostly stock 340. The advantage is I use a billet filter plate
on the block and no angle adapter. And it just clears the 1969 340 exhaust manifolds.
Yea I change it more often, about every 3 years, and that's around 1000 miles.
I use 10w30 synthetic oil in the engine and the engine hardly ever sees anything north of 5000 rpm.
The oil pressure has always been good so I never worried about it.
