i just yesterday picked up a EAB flathead all complete not locked up can turn it over with a battery and spins great got to give it a tune up so it will run . . but my question is i was old it came out of a truck so was there a certain year for the EAB ??? and was it for a car or truck ????
It's been a couple of months since your post, so you probably already got an answer to your question somewhere. I just found this part of the forum today. After 60 years, your engine could have a lot of swapped parts on it. If you are going by the markings on the heads, I would say you've got a '52 - '53 engine that's probably from a car. They were usually painted red when new. A '52 truck engine was still an 8RT, but not sure about the markings on the '53 truck heads. I've got EAC heads on my '52 pickup and they're from a '52 Mercury.
53 truck was still 8rt markings , my 52 customline was running an eab when new , but was replaced later in life by a 53 8rt . eab heads can handle .395 - 400 lift on the valves without machining , and have a small chamber of 69 or 71 cc for a boost in compression , so they are worth keeping . my 53 effie is running and 8ba short block that is soon to be freshened i hope , with the eab heads milled .010 for cleanup , and should be running like 7.8 compression .
