You know, it doesn't really make sense to impose "year of the block" emissions requirements on service blocks (which, if you have a 1974, is what you have -- I'm pretty sure you couldn't get an FE in a car in 1974). You were generally buying it to replace a bad block and, presumably, when you did that they still held you to the standards of whatever year your car was from the factory. Before you show up in front of the emissions guy, see if you can't get a better answer from someone around here. Surely someone has gone through NJ emissions.

patrickt - make sense? One must remember who we're talking about here.

My guess is that I'm making more of this than it is, but I like to have all my bases covered to be sure. It's just that from everything I have read, everyone refers to "pre 1974" and "post 1974" in their commentary but doesn't say anything about 1974 itself and I want to be sure I didn't miss something. As far as I know, no one "pre 1974" has had to do anything more than a pcv valve setup.

I'm pretty sure 1975 was the first year for cat. converters -- remember they had to change the gas pumps and for a while you had the little skinny gas pump nozzle and the fatter nozzle for older cars. (because of unleaded fuel)

I don't want to hijack the thread, but I agree that 1975 was the first year for Cat converters. The reason I remember is that my dad had a new '75 Pinto that was rear ended and he cut the back off and welded on a back of a '74 Pinto to it. I was pretty young, but I remember a discussion about what to do with the new fangled Cat converter thing......I think he just threw it out. So we had the only '75 car in town that still took leaded gas!
