    Hi Fast,

    Always interested in your progress on this.
    Whats up with the 12.3V battery voltage on the dashboard display, isn't that a bit low?

    Cheers,
    Andrew

    I need to replace the alternator and finish wiring it up.

    Put a 145 amp AD244 on it and wired it up. Charges perfectly now. 14.5 on a cold start and settles down around 13.8-14.0 when it is hot.

    Thanks and they do. Bit of a mystery why long terms and short terms are as far off as they are, but they are correcting in opposite directions and the actual air/fuel ratio is close to the commanded, so does not concern me. The PF4 does not activate the long term correction updates until 165F. I think with more run time and mileage it will all even out.

    I found a NOS, discontinued Spectre air cleaner housing I have had my eyes on. $250 at Summit when Spectre last offered it for $150 on Ebay and it comes with the re-useable 14x4 air cleaner. Seller still has 8 showing available at this time, just FYI. I found some large scoops listed for saw dust collection, that I plan to fit into the front core support on each side of the condenser. Also found some 4 layer, insulated flexible 4" duct that looks like the single layer plastic intake tubes GM used on the 70s and 80s vehicles externally. Thus it is getting a dual 4" cool ram air intake system. Should help out the intake air temps a lot on a hot summer day preventing hp loss.

    My plan is to tape off the lid and paint the sides and bottom with universal semi gloss black engine paint, leaving only the lid shiny like the old LT1 or Z/28 350s.

    Nothing like keeping the factory look.
