Originally posted by Greg Kelley I run them and installed them on quite a few customers cars as well. No problems but all are race only. Would idle clean @ 700 RPM if I wanted.
I've found that yes, they are a bit too big at idle. It will still run and all, but getting it to idle at say 14.6:1 may be a small challenge lol. If you graph the inj pw at idle with 160's you'll likely see a nice flat line, pegged at min pw for most of the time...
