I just stopped by the hanger where Donnie's working on it, the car looks like it's going to turn out nice. I also may be able to clean out some of the spare LS parts in my garage.

Sorry I missed the fun Gary/Donnie. Hanger is going to be a busy place this year. I plan on replacing the old school 427 in the Blue Angel 69 when I get back from wintering in Florida. All Aluminum BB is in the planning stages up at Competition Marine. More to come as we exit the planning stages. My main requirement is to be compatible with the stock GM L-88 hood and its air chamber. Also Heads need to be a compatible height so the Hooker side pipes fit with no fender mods.
Gary, I was thinking Don would be better off keeping the new Holley Avenger ECM rather than jury rigging a GM LS ECM with EFI-Live. Lets talk pro's and cons of the two approaches.

Not too familiar with the holley. But the GM stuff is cheap, widely available, and suupports 400hp on the LQ9. On my LQ9, I was planning an L92 head and cam swap. But the stock motor with exhaust and mail order tune is nearly 400hp, 400ft/lbs and breaks my stock 7" wheel and tire combo lose easily. I think Don is going the same direction.
411 ecu $50, mail order tune $75, and a pick and pull harness is hard to beat for the cost.
Any chance that aluminum block is an LS7, or are you going old school there too, 502 or 540? Just enough to scare Chip in the passenger seat anyway.

I purchased a Holley Avenger system 550-400 for my old SBC. Considered using the computer and wiring harness but after looking at it might work. Smaller unit than Chip uses.

That looks just tunable enough for me to screw things up really badly. Same reason I never bought EFI Live or HP tuners.

That's the nice thing about the new holley computers. They self tune so if you keep you fingers off the key board it does the work. Going to stop and talk with Chip about it sometime this week since I already have one.
