A while ago, I posted wondering if anyone knew whether or not a carburetor from a newer Chevy 194, 230 or 250 six cylinder engine would work on an older Shitbolt six, and never got a clear answer, so I figured I'd just try it and see! The 235 came with a Rochester one barrel that, like all Rochester carbs, ran like shit, leaked like a sieve and delivered horrible gas mileage. Add in the fact that the previous owner is one of those folks who suffer from an acute case of filterphobia, and you know it won't be long till a new carb is in order! Having had plenty of experience in the past with late 70s vintage Chevy 250 engines in a plethora of Novas and Camaros, I already knew that the best carb for THOSE engines is the semi-ellusive (these days) Holley Economaster replacement 1v carburetors. These fit in place of the awful Rochester carbs and boost fuel mileage and performance CONSIDERABLY on a 250 Chevy six, so I reasoned that it might be a good upgrade for a Shitbolt six as well! The only questions remaining now were could I find one of those carburetors and would it work on this car (55 Chevy)?! Lucky for me, Mayfair Speed & Machine Shop just happened to have a selection of NOS Holley Economaster carbs on hand that Dan dug outta the back room, and in the pile was one brand new-in-the-box Economaster 1v designed as a direct repplacement for 1977-78 Chevy 250 six cylinder engines...just what the doctor ordered! I was able to buy it stupid cheap, so the next quandry to address was making it work where the original Rochester failed so miserably! The first step, of course, was to rip that leaky old stock carb off and throw it as far from the vehicle as possible! Then, I was able to cut the steel fuel feed line and install a Wix 5/16" universal fuel filter, as the previous owner should have done!
