" From: "Mahoney, John" <jmahoney@xxxxxxxxxxxxxxxxx> " " " >> " afaik since they introed the 472 they've had only one caddy v8 [472, " 500, 425, 368], and that was a redesign of the previous 390/429. " << " " No, it wasn't. GM's leap beyond the 440 and 462 (Chrysler and " Lincoln) for 1968 was an *all-new* engine. The 390's 4.00 x 3.875 " had been bored and stroked (4.13 x 4.00) in '64, but [80-pound " heavier] 472 was 4.30 x 4.06. The '70 500 was a 472 stroked to " 4.30 that, until 505 V-10 Viper debuted in '03, remained modern US " regular production displacement king. The 472, lightened (by " 100-pounds) and lessened (4.08 x 4.06 = 425; 3.80 x 4.06 = 368), " became the L33, L35, and L61. i stand corrected. either way, if the caddy hei does fit the amc, it'd be from a mid/late-'70s 472-gen v8. and btw i recall when the 472 came out, a caddy engineer said 'there was room for 600 cubic inches'... ps. '67 was the swan song for the ford 'mel' engine family. i speculate that some emission reg kicked in for '68 that caused lincoln to switch to the 460 starting 1/01 - mid-model-year. in some ways this was a step down; since the 462 [and ancestor 430] was built only for lincoln, they could afford to be more particular about it. i read in the lcoc club newsletter that every one of these engines was run for 2h on a dyno, including 30m at full throttle, prior to assembly line installation. certainly it is true if anecdotal that they are famous for going 250 000 miles without needing overhaul. i don't think the 460 has that kind of rep. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
