Thanks Doug
quote:I sold my Doug Nash intake because 1) I could not negotiate a pair of carbs that I could afford and
They are novel and highly sought after by collectors. They fetch a pretty penny.
quote:2) the only way to close the bottom of the port is to fabricate a spacer plate to the A3 heads. I suppose the Devcon epoxy will work but in to many cases it has come loose and gotten sucked into the intake.
Very true. All depends upon how permanent the intent of installation I suppose. People tend to reinforce Devcon with pins or fashion aluminum chunks for the bulk fill, mechanically secure, and Devcon the rest. I think it can be done reliably but certainly understand the angst.
quote:As I recall, there was a question whether or not they would fit on the Weber intake and it looked like a 1/2" adapter plate would be necessary. The Hall ida intake had a slightly wider carb spacing then the SB Ford but not by much.
Yes, but inlines have 4 3/8" bore centers. IDAs are 120mm between the carb centers and the distance between the center two barrels on weber intakes vary but is always less than 4 3/8 usually no more than ~4" (at least on most small block versions). Because the IDA bores are only 48mm, you can usually get the IDA bores to fall within the bores of the larger 9510B inline, but you will end up with fair asymmetry in your runners by th etime you match. The adapter plate would save cutting up the IDA intake but their may be some challenges getting uniform flow in each runner. Where there's a will there's a way.
quote:They were tempting because the carbs are not as tall as the Webers and for the Pantera that is a plus.
It's still very difficult to get a set under the lid of a PCar. I have a modified tunnel ram base that will go with 1 1/2" tall oval filter elements, pictured below. No way to get inlines under the hood on a Nash intake with any reasonable filters.
quote:How many of those manifolds do you think were made?
Very difficult to say. Pure speculation but I would say in the hundreds of sets, perhaps a couple thousand. The only reason it could be thousands; the Nash intakes were actually intended for mechanical injection. Inlines were an after thought. Hilborn, Falconner Dunn, Enderle, and other sbf mechanical injection intakes all have the proper bore centers. The Hilborn B302 intake works very nicely. I've seen some nicely done adaptations of other intakes, usually tunnel ram bases with adapter plate(s) welded on. I've collected lot's of pictures over the years. I think I've rebuilt or restored between 50-75 of these carbs now.
More later.
