EFI, Alpha-N vs Speed Density fueling Strategies

[Ed Wright]

I used an Opti for a while. Not gutted. It can be done with the Opti electronics, although I nener tried it. Some of the Stocker guys are doing that. I now use an MSD dist with cam sync. I didn't find sequential to be the huge HP deal some make it out to be. Still, 5 to 7 hp is worth the effort. I had 2 cyls 9 & 10% lean, the rest were 2 & 3% off.
