The 350 crate engine I bought from goodwrench stated that it was made for offroad use only as it would not pass emission standards. The 350 is listed as pre 79 and is 330 horse with 380Ft lbs tourque. The loop hole here in Vancouver is that if you raise the GVW you get into commercial grade insurance and don't need to go through air care. It cost about 20 bucks more for insurance but no hassle involved with testing. 20 bucks well spent in my eyes
