I used the Moates.net BCC spreadsheet to find the V8 '427 PCM Memcal part numbers. I used the part numbers at an online GM parts supplier. According to the research I've done the 18 Memcals I have a screen shot of are still available from GM. Depending on the GM parts supplier, some of the part numbers were listed as low as $33.50! Who knows, next week GM might make some / all these part numbers obsolete.
