M1 or Port-Matched LD4B on 408

regarding the switch to sniper efi: i run it on my 408, works fine. I had some trouble with RF interference, could be solved with some adjustments in the tune. This was with a magnetic trigger distributor, you should check out the new Holley Hyperspark distributor, it´s got a hall-sensor and no un-necessary advance mechanism, and it´s cheaper and more easy to install than the dual sync.

regarding the intake: i switched from port matched EDE Performer RPM to a port matched EDE Victor.....lost a few hundreds 60ft. So i think the EDE Performer RPM is the best bet for a true street / strip.
