if i re call right there was a book about the slant six right?

There have been several, but most are outdated now or were full of wrong information when written. Your best source of information is this website. Look at the FAQs in each section and use the search button. There is a mountain of good information on this board.

hi sages- read the frank adkins article today . its really very good. lots of details about the evolution of the sl6. been fooling with these engines since 64 and picked up a few things about them i didnt know. didnt know until recently that the 170 was an interference engine but never heard of a 170 wrecking itself even when a timing chain jumped or busted. adkins points out that it was interference. have heard a few mechanics mostly young bucks refer to the slantsix as a dirty engine from an emissions standpoint. is that factually correct? thanks tons bob f

All engines and cars of the slant-6 era had very dirty emissions compared to today's cars and engines. The slant-6, along the years, was usually not significantly dirtier or cleaner than any other engine of similar displacement, though Chrysler did a better job earlier than the rest of the American car industry at cleaning up their cars' exhaust in the 1960s. By the mid-1970s, European cars with fuel injection and Japanese cars with advanced combustion chambers were putting out exhaust considerably cleaner than American cars with cheap and nasty emission controls.

hello uncle dan- read the '63 pm article you referred to in answering my dirty emissions question. some interesting stuff in there. does show chrysler had an early start with emissions reduction. have heard before on older engines that retarding spark timing increased pollutants . had a 69 coronet 318 with a 3 spd stick which called for initial timing to be set at TDC which i thought was strange b/c that would increase emissions. advanced the timing to 8 degrees btdc .but had to lower the idle back to 600rpm. car got better mpg and still passed the tough as hell nj emissions test. didnt advance it any more than 8 b/c it would ping on regular fuel. figured retarding timng as a general rule would increase emissions of hc and co since you were decreasing burn time . moe told me that was true but advancing timing would increase nox . what do you think. back then nj checked hc, co and smoke but not nox. moot point today since timing cant be adjusted on these new tanks. regards bob f

It's really not that simple at all. Overly-advanced or overly-retarded timing increases emissions. Within the window of reasonable timing, retarded timing tends to reduce emissions at idle and certain other conditions.
No, it would not.
There are no tough-as-hell emission tests, anywhere in the United States, for 1969-model cars.
Not correct.
Under certain engine load conditions, yes.
