Subject: RE:GM LQ9 6.0 Engine - C4 Swap? by bogus on 2008/1/13 2:21:41 So 1981 it is... cause the prior change was in 1978 or so... My mom's 78 Audi Fox didn't have a cat (Bosch K-Jetronic, I think) and neither did my first car, a POS 1976 AMC Pacer, 258 I6 with a massive (ha!) 1 bbl carb. I am pretty sure my brothers 78 Datsun B210 was cat-less as is a friends 1979 280Z (EFI of some kind). I am equally sure that my oldest brothers 1979 Chevy C10 pickup (250 ci I6) was catless. One of the reasons that Japanese Imports were not immediately effect by emissions controls was that they didn't need them! For the most part, the smaller more efficient engines in the Japanese cars were that much cleaner than the American sourced engines. Same for many of the smaller European cars. However, a lot of the OLDER Euro cars - mainly MGs with the push-rod Austin based engines were dirty pigs, so they got nailed... Jag did too... the XJ motor had some icky nasty heads, too. I know that fire, police and park ranger types can still order vehicles without cats - fire hazards in remote areas. |
