well at least with the 460 Ford they are a lot more common and easy to find than the 370 truck engine. Altho you know a lot of the old engines and vehicles were scrapped back in the early 2000's when China was buying scrap..getting harder and harder to find anything from the 80's era of vehicles..even just trying to find an unmolested 350 Chevy is a challenge..best of luck with it Sonny
