custom intake...
how difficult would it be to make my own tunnel ram intake? being only 18 and quite mechannically inclined i'm always up for a challange so if someone could tell me what to look for and what to do for a dual carb intake let me know!...please...

RE: custom intake...
well i know www.summitracing.com and www.jegs.com sell complete set ups in low and high rise.
or you can go to swap meets or ebay and buy an intake and get new carbs and linkage its etc..
here is one i had on my 69 camaro and my 68 vette has a low rise dual quad set up

RE: custom intake...
If you are an expert -- an expert--at cutting, bending, and brazing/welding sheet metal you can make an intake manifold that will fit. But the lengths, widths, curves, etc. of the manifold are just so involved and intricately tied up in engineering of air flow dynamics, that, no offense, you would be a fool to try.
C3s were carburated -- the manifold conveyed not only air but fuel-air mixture. So, not only were they constrained to all the usual, modern automotice physical considerations of air flow, turbulence, etc., but their designs had to assure no dead spots, etc, where fuel would condense out of the airstream (this was a big problem with some tunnel ram manifolds at low RPM, low power). it was very difficult to design a good manifold. Many manifolds of the period -- even well engineered ones -- had problems with low RPM idle and throttle response because air speeds at low throttle positions would drop and fuel would condense to the bottom of the maniofld -- the engine would bog and not respond well.
Bottom line: it is just not feasible to design and build a home-made intake for a C3. Find a good design at a swap meet or from a reputable speed parts supplier. Those companies had the engineering staff and the experimental labs to get it right. Alone, you never will.

RE: custom intake...
well, unfortunately my new found information has forced me to get rid of my baby, but not in vein, i got a 1965 chevelle wagon, as soon as i get back on my feet and home i'll be buying another vette, possibly a better one. (l88) mabye a 72 or older. but ive got some ideas about this intake to prevent fuel from settling, i've got some buddies who will be assisting me in this event, so worst case senario is it dont work and i keep whatever is on it. thanks for the insight!
