John Arruzza probably has the most experience with that intake. Call him at 919-918-7584.

For what it's worth, that intake is mostly a repop of the old KB/Chrysler marine intake. The Holley carbs for it were (I think) 4127 & 4128. Holley may not have made carbs with that number but modifieds 3116's to that number. Good luck. Remember you don't open them in stages like a street hemi. Open them both together.
