  2. Why not just homemade intakes?
    SBC folks usually buy not build

    Doesn't the coolant run through the manifold on a SBC? I've never had one so I don't know.
    Neat setups guys though. What carburetors do you run?

    I would like to do either a tunnel ram or one like the green manifold above.

    I'd like to run a couple carbs, however I don't want to run vintage gear, I'd rather run re-pops and leave the real stuff for you guys who need it, it won't be going in the best car.

    I have found out over time that homemade intakes don't perform all that well. Yes, they look cool. That's why me and my buddies call them anti-speed parts.. I love the look of a crazy homemade intake though...Jason.

    I'll keep the Y-block theme going, with a few I found on the web.
    Sure would like to see more of Dana Barlow's 4-71 intake.

    We're going to start making these with several different tops. Dual quads, 4x2 for 2GCs, 6x2 for Holley 94/Strombergs, 3x2 for Holley 2100's. The 6x2 will be like the Weiand supercharger topper where the carbs are staggered. Don't know the selling price yet.

    This one was made by my dad, uncle and grand father back in '67 or so. It's sitting on a Packard engine and was made from pieces of a cut-up drive shaft!

    Stock singlebarrel intake with two more carbs added to it on my 292 Chevy motor in my '29 Nash.

    I modified the original single carb intake. The 3 monojets are linked with progressive of my own design, bellcranks are configured to bring in the end carbs at 1/3 throttle, then at full travel all are full open, due to the geometry of the 'cranks. Took a while to get that figured out, 'cause I'm not a mathmetician, just a trial and error kind of guy.

    Choke is on the center carb. Works great! Starts easy, tunes to perfection, idles excellent. Goes like hell. With dual straights out the side scares little kids and old ladies.

    First picture is in progress before I finished the linkage. When I was building it I didn't think to take more pictures. The end carbs are on riser blocks milled to line up with the center one. I detest rubber/plastic hoses, these are steel with brass fittings.

    Also, contrary to a lot of myth, I have found that adjusting the idle mixture on all works best for me. Closing off the ends and working only from the middle don't get as smooth an idle. Mabye with more than three it would apply but with three it's easier to tweak them all, gets a lot more consistent and smooth idle. Start off with all butterflys closed down. Crank it up, adjust the speed on the center one. Adjust the mix on center, the ends, come back to center, etc. until it's purring. At that point the speed will need to be tweeked. My logic? For sure on a L6 change in the mix on one end has absolutely no effect on the other end.

    last pic is concept, see wood blocks.

    'look'? I will alwas prefer something I made myself to something somebody else made...........

    I was throwing around the idea of Webers on my three deuce manifold for the y-block build.
    I can only imagine the sound that would give the Y-block.

    this one was done in the 50`s .it is a cast iron manifold modified by welding plain water pipe to the stock manifold.if you look close you can see the threads on the ends of the pipes.it was done by rossini brothers speed shop in toronto,canada.speed parts were hard to get in canada in the 50`s and this was a solution.it looks like it would work fine and will take the 94`s.the flanges are lined up perfectly.Bruce may have thoughts how this one would work.this one was used on duke deadmans`s flathead dragster before he got the 4x2 manifold.

    this one was built locally and aparently worked good.it is based on the 49-51 merc aluminun manifold.it takes the newer carbs.i wonder if the wide open chamber below the carb would cause a lean condition to any of the cylinders?Bruce?
