Default Oil Filter

Anyone with a 69 350/350 use an Moroso long oil filter do you have to increase the amount of oil in the motor? Ex. 5qts to 6qts because of the length of the filter?

yes you do ......they used OEM long filters in vans and heavy duty trucks back then to give more capacity for cooling purposes. just trust your dip stick on this one

I use the long truck filter on both of my small block coupes. The filters I use are made by Fram. I just ask for the truck filter at my local auto parts store. Jerry

Add the extra......fill your filter with oil before you install it
Then fill your crankcase til the dipstick reads full, youre set.
