Two superchargers would work they will cram air in big time
just a matter of enough fuel to not go lean. But NASP
engine trying to suck air/fuel in through a carb ment for strait individual runner's, now with open plenium, different deal. How much suction is being put on the individual throttle bore ? compaired to open plenium ?
runner length now looks to be very long almost a 180
degree bend in the runner from carb flange to head runner opening.

DB
The side draft carbs or webers are designed to be used on individual runners, each throttle bore has its own individual runner generally with a very nice strait path runner to the head. Think about what will happen to the carb that is ment for one cylinder pulling out of each individual throttle bore now put on a plenium manifold. Besides screwing up the individual part of it if you look at your picture regardless if you change the distance on the carb spread, between the manifold runner of the head
to the carb flange you have created almost a 180 degree bend. What bogus told you is correct other then the looks value you are creating a mess. Air traveling in as strait a path as possible is always a good thing two 90 degree bends in the runner not good. then there are certain runner lengths that are known to be good for an engine things like goofed up runner length messing up power bands.

I'm not trying to be negative, looking at single four barrels on an engine is a little boring everyone has one. Consider something else.

You were one of the regulars on the other forum always tried
to help people, I noticed some a couple yrs ago would try beat up on you only because of how frequent you visted the forum, far as I know its still a free country as long as you stay within the rules set down by the moderators of the forum and you did, I could not see why they gave a damn, guess they got jealous real quick because you had more stars then them lol, kind of laughable that people can be that way.

Anyway decided to come over here see if there is something I can add to this forum.

Age does not bother me, from a vain standpoint I look younger then my age, my health has always been good I'm still the same crazy hot rod nut I have always been, nothing wrong with keeping something original from a money standpoint the wise thing to do on some cars, but if I can't modify it or hot rod it some way I'm just not happy lol.

Thanks for the warm welcome and to the moderator that took the time to welcome me. I do not own a vette will probably
be another yr before I can buy what I want, I call myself
Little-Mouse, the first form of performance car I owned was
a 69 Z/28 followed by a 72,73,66,78 vette in this order,
73 and 78 I bought new so its been a long time without one.
Right now I have a 2003 t-bird with 12,600 miles on it a
63 lincoln conv for toys to play with, the T-bird will go to help pay for another vette. I do have some 1970s machine shop experience built a lot of small and big blocks over the yrs so hopfully if nothing else I can be of some help to some on this forum.

Hello
I'm an old fart lol, closing in on 56 hope to learn from this forum add to the discusion's.

Are you going to run fuel injection, my understanding narrow
lsa (higher overlap) has bad effects on fuel injection if thats truely the case you should go to a wider 112 LSA. I did not notice any mention of a .900 base circle, will you not need the .900 base circle with a 3.75 stroke.
