I've dealt with these guys in Tacoma a few times now in the past few years. Every time they go way beyond what I'd expect to help a small time hot rodder building a motors in his garage. Yesterday I needed pushrods for the 452, Scott gave me a set of 16 at the length I think I needed, and gave me his measuring rod, said "here if they fit, great, if they don't, measure it up & let me know what you need.... We'll just settle up once we know you've got what you need."
