Turn the secondary carb over and you will see small holes running from the base up past the mixture screws and into the venturi. Plug these off with lpermatex liquid solder. Remove the choke and install plugs into the air horn where the shaft was and pull the top off the carb. Disable the power valve.
I asked Marty about the blower manifolds... he said he would love to make them but he has too many projects on right now. If I had a boatload of money, I would have them made up and resell them yesterday! AND I would have #1, #2, #3 AND #4! ha ha ha
I own the original Weiand pattern for the blower manifold for 401 and 425 but the core box is MIA. I would have a new core box made if there was enough interest.
A core box is the mold that casts the sand "core" to make up the hollow interior of the part. After the aluminum is poured; It is broken up and removed from the interior.
"The idle circuits must be eliminated. turning the mixture screws all the way will not work." Why? and How? I was recommended to leave secondary carb's idle circuit intact by one of our Gurus whos advice I feel comes from many years experience (to avoid stale fuel remaining in bowl- since secondary carb is only put into play during exhibitions of speed). I can appreciate the potential fuel savings by not having the 2nd carb feeding idle, or is this elimination step pertinent to proper running?
i have been thinking about making a nice aluminum sheet metal intake. been waiting along time for this alum one. it's has been so long i have learned how to tig!!! i do give credit that he has atleast made some production nailhead parts.more than i have done. to bad buisness skills need improvment. paul 66larkgs turbo nailhead
