I believe the main problem with long intake runners is fuel distribution. I'm not an engineer, but I think the longer runners are actually good for tourque, but if I remember correctly, the fuel can't atomize going through such a long path. By adding injectors at the ports, you avoid that problem and get even fuel distribution. Gm port FI motors have long runners, but they are curved, the ones on the right feed the left side of the engine and vice versa. Check our RANCEFI.COM. They have some cool set-ups. Too bad it costs so much. Rob _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
