Most of this thread is way over my head but will say I have a k27 evergreen raptor mod turbo in my 76 3.0l short stroke mostly stock with an I/c and sc cams built for reliability not HP it's my fair weather driver ... I really like the gradual spool up has a really nice controllable spool up ,unlike the 3ldz that's basically works like a light switch. On and off . I had to add the rpm boost solenoid to lean out the boost. 4200 rpm is a good spot for the boost dump for my car 13.8afr just before the dump and 11.2 afr full boost ...
