    MAF EFI Conversion From Quality Roadsters

    Good morning,

    I am contemplating installing kit for a 355 SBC in 68 Camaro. What does every one think about the MAF System? Versus the Holley and Edelbrock products? Versus Speed-Density-based systems?

    Thanks

    A MAF-based system will be more precise (which is why OEM's use it, the more precise airflow measurements of a MAF system allow better control of emissions) but a good speed-density system also does a fine job.

    They aren't very specific on the website, but it appears just to be a Ford EEC-IV system coupled with a specialty hotwire MAF sitting on top a 4-barrel throttle body. The EEC-IV is a good computer.

    Also, I don't quite buy their "no programming" thing; you'll still need to tweak acceleration enrichment, cold start parameters, timing tables, target A/F ratio tables, etc, for your particular application. Nothing is ever a "one size fits all" when it comes to EFI as there are SO many system variables. I can't find any definate answers or user manuals on their website so I can't say for sure.

    I'd find out more info before I dove in. However, I do like the idea of using off the shelf OEM components whenever possible for easy parts availability and serviceability, which is what this system appears to offer.
