Cliff is everyone's first choice for Q-jets... which means a long wait time. If you'd rather not wait you can buy his book and rebuild your own with one of his kits.
Another option if you don't want to wait (or, like me, lack the ability/patience/knowhow to do it yourself) you can contact Jeff Walker (also a member on PY) and have him build you one. I bought one from Jeff last summer when I did the 2V to 4V swap on my Lemans and he did a great job. No issues, no fiddling/tuning, fired right up on the first turn of the key after install, very happy with the result. Reliable and still running great a year later and happy enough with the result to give him some free advertising... that says a lot these days. Just my
