There is a place in the states who has all the old stock from Speed Pro and TRW. I bought rare singles from them before but can't remember what they are called!
I got the name and number off the HAMB, so if you ask there - someone will have the info.
thanxs racerrick, i've already scored a complete set of some open chamber stock bore 427 trw's for the build. i'll keep this note for future reference because i still have the set of 7 (3888304).
