OT but FYI I had a pair of Holleys for the KB Marine intake once. In case anybody is wondering I believe the numbers are 4127/4128. Mine were built by Bauman I believe, based on the handwriting. They were made from 3116 carbs. I wish I would have put that intake and carbs on something and drove it. Someone later told me not to use staged linkage with those. Have both primaries open together. I asked KB once how many of those intakes he made. He said he didn't remember for sure, maybe 75. Just passing on the info.
