The EC engines were 1.8 used in the 914 and 411/412.
The engine number location would seem to indicate this engine is from a 411/412.
Also the dipstick tube looks to be covered with a hose? Possible spme me fabed a rubber dipstick tube to relocate it for use in the 914. 411/412 dipsticks were similar to buses and go down low by the front engine mount.
All stock 1.7 & 1.8 engines used 4 bolt intakes as so did the 2.0 bus engines.
914/912E 2.0 were the only engines to use 3 bolt intakes.

Like I said 1974 412, they didn't make a 411 in 1974.
Why I also asked about the dipstick.
I've seen the web site that says EC is a California only code, but it's wrong, my Canadian sold 1974 914 had an EC code engine with no smog pump.
Look at the front of the engine case, right side bottom you will see a cover plate, big hole two bolts, likely homemade.
