I recently had been talking to Blueprint engines because when I initially filled my 347 engine with 7 quarts of break in oil, the level only showed a 1/4" from the bottom of the dipstick. Both times I talked to Blueprint, they explained the engine should have a total capacity of 7 quarts of oil, 6 for the sump and 1 for the filter. After talking to one of the other guys on the forum who had a totally different outcome with the same engine I decided to look into the oil pan. Both of us have the same Canton Racing Products oil pan, 15-610 For Ford 289-302 Front T Sump Street Pan. I decided to give Canton Racing a call this morning because the oil pan description stated 7 quart system and I wanted to verify Blueprint was correct and that it wasn't 7 quarts in the pan and 1 in the filter for a total of 8 quarts.

After talking to the technician there he explained this is a common question they get all the time about oil level not being on the dipstick when the proper oil amount is added. 6 quarts in the sump and 1 in the filter for a total of 7 quarts is the correct amount that should be added to this engine with this oil pan. He explained that they use a common dipstick tube across most of their oil pans and that the tube should be cut to size with a pair of tubing cutters. For example, the oil level is 1-3/8" below the FULL line with 7 quarts of oil added to the engine and prelubed throughout, which means I need to cut 1 3/8" off the top of the dipstick tube.

The reason I'm sending this message out is whoever may have a Canton Racing oil pan with their Blueprint engine, you may want to check the length of the dipstick tube and level with the appropriate amount of oil added for proper setup. The distance from the bottom of the oil pan to the top of my dipstick tube is 24" at the moment while another member's distance was 22" and only his engine only took 6 quarts to reach full. This unnoticed error could be a matter of being a quart low or a quart high based on the length of the dipstick tube.
