    Verry cool project! Are you planning on running it in batch fire or fully sequential?

    Thanks PJ....

    2JvLo..
    Batch fire. For a couple reasons...
    A) simplicity

    B) I'm running an ms2 which doesn't easily support v8 sequential

    3) I donot have the equipment to be able to tune anything well enough to take advantage of sequential.
    I only have 1 wideband o2 sensor and a butt dyno lol

    Yeah, I invested in one of those butt dynos myself. It about a size 44 right now, but is expandable if the need were to arise!

    I have a very narrow butt dyno.:)! BUTT as I was saying, an air intake temp. sensor mounted under the intake instead of the intake tube should give you a lot of info.

    I've always wondered where this type off dyno's came from, And an expendable one seems like a must have! :laugh: Any cheap suppliers at the moment??

    Kzhutley, Seems like you thought it thru. Looking forward for progress!
    Where are you going to get your trigger signal from ?

    Soon to be In process of fabbing up a 36-1 trigger wheel. I had a northStar ignition setup but going back to distributor for looks. So have a pretty good start for the reluctor.


    Problem with the butt dyno is that it's portable and works anywhere.. Even in front of law enforcement which I suppose may get you into trouble. They give you a little slip that give you a mph and a $ amount you get to pay for thier services.. Couple of those and you could've used a chassis dyno.

    Already have a chassis dyno. Been with her for years. Just doesn't seem to hook up anymore:(:mad:. I think it's broken, maybe try a newer model:).

    My earlier question about who fabricated your fuel rails results from the need to have my own rails done. I'll probably go with the "store bought" tool to drill the injector holes (Ross Machine - https://www.youtube.com/watch?v=iSNb9QKj568) but the question was what tool to use to make the o-ring bevels for the end fittings. What did you use - and what size? My line will be Dash-10 (5/8).

    Thanks,

    bro. d

    Mine are fully welded.

    The way I did mine were as follows...

    Sawed to,length, and made plugs press in ends of rails and welded them in.

    Located and drilled pilot holes(believe 3/8 maybe) then drilled and reamed to 14mm Mayne 5/16 deep and beveled injector holes,

    Then milled a flat on each rail at tje correct angle I needed and bored holes into the side. Then used -8 female weld bungs that I turned down in lathe with a step to locate in the rails. Then welded those up.

    Then I just have -8 bulkhead fittings without nuts so I can bring feed and return lines above intake..
    The crossover line is just drilled and tapped 3/8 pipe thread and 90° fittings.



    Hope that confuses everything lol

    This is the first one of my intakes I've seen anyone other than myself do anything with! Looking good! You seem to be talented enough to have built your own...Moved to Texas and and had a rough start but am ready to start building again. Built a single plane curved runner intake (High rise), mounted a turbo directly to carb inlet and made 2x4 draw thru intake for that...really tall but oughtta be fun in my 507 powered T bucket!

    Good to see you back up and running again.. I like the turbo idea youve got going.
    The intake I got from you just ended up working out perfect with the factory 1956 2x4 cad air cleaner.. Height wise I have about 2" hood clearance.

    Another update:

    Got the valley pan and gaskets cut and bonded up. Installed intake and bolted down hopefully for the last time on this 500..

    Throttle linkage took some figuring as I had to highly modify the original bellcrank system. This 500 has much less room head to firewall because of the opposite cylinder bank offset.

    Next it's harness time. I've studied way too much on what plugs I need.. I'm using all GM sensors and such. I usually just go junkyarding and snip the plugs off what I need and solder them up for harness... Not this time. I wanted to do the harness without any breaks lol. Delphi metri-pack 150p is what most of them are. Very cheap new, but alot of variations to what they can be. Like once you figure out what plug you have, then you have to buy the right pins and seals for the gauge of wire your using. Also the crimping tool is needed. Good thing I only actually need like 5 plugs total.

    Then finally I'll be moving onto the crank trigger and pickup. I have another 75 500 on a stand that I can use for mockup since there's no room in the car to work..

    The connectors can be had by Tray maintenance. Don't now if they have a site. But I do know they have the connectors. Try and get them from the dealers:(. Good luck. This is a very good tool to crimp twin lock connectorshttps://www.ebay.com/itm/Buick-Wiring-Harness-Crimp-Connector-Wire-Terminals-Crimpers-Tool-nos-14-18AWG/301309236789

    The tool i have looks just like that, except i paid 2x that lol..
    I found through gmpartsdirect I can get them, but its hard to find them without a part number. A little searching they come up and I can then order them.

    Tray Maintenance used to have pretty pictures. I like pretty Pictures. The reason I know, is I do this stupid shit for a :sick::geek:o_O:cry:living. But now I think I'll just shoot myself.
