Re: \'81 with a 327?
Seeing how I live in Washington State were the SMOG laws are so very different from California's SMOG laws, I'm wondering about the engine thing. If I'm reading the posts correctly, the 1981 truck, according to California SMOG law, can only have an engine that is not older than 1981. So now I wonder, would it be legal to install a new 350 HP 350 cubic inch ZZ4 GMPP motor in a vehicle subject to California SMOG laws?
I have it very nice here in Washington State, no underhood inspections, just a tail pipe emission test (HC's CO's ect.) run on a chassis dynometer, and a gas cap pressurized vapor test. It's nice to put whatever you want under the hood, but in Washington State your stuck with the emission limits of the Make, Model, and Year of your vehicle. Funny thing though, most vehicles after 1981 have about the same emission limits. So if your vehicle is missing emission equipment like a catalytic converter, or has headers and dual exhaust and can pass the emission test limits for that Make/Model/Year, you can have whatever engine your heart desires. Vehicles 1975 and older don't even need to be tested.
By the way, a similar early 80's GMC Stepside 4X4 sold for $2900 here. Looked real nice, and ran like extremely well for a 305 pickup with 135,000 miles on it.
