So, the banger is 4 cyl.. but only 2 intake ports... the motor fires 1243..my thinking is it's 2, 2 cylinder motors.... next, when you put a header on... the intake gets real hokey ... what I wanna do is run 2 one barrel carbs and split the intake... and weld the intakes to the header flange... seems to me tuning would be a breeze with a carb for each intake port.... might even find where they hid all the horse power to these motors...as it sits the banger is the secound worst motor built... @ 10 and less hp per cyl... first place for the worst goes to the 32 flat head v8 with a little less than 8 hp per hole.... I know the blame goes to the flat head design..... but what about the intake on the banger.... think 2 carbs spit intake will wake it up???
The 235.5 cid engine was first used in 1941 trucks. All of the six cylinder engines had panels retained by binding head screws with the nickname "stove bolts", so the engines picked up the nickname "stove bolt". I'm not sure when the term Blue Flame started, but I expect it was in 1941 on the 235.5 cid engine. All Corvette six cylinder engines had three side draft single barrel carburetors. From 1953 to mid-'54 all carburetors had a bullet-like air cleaner that did little more than keep out small gravel. In mid-1954 the 3 carbs were fitted with a manifold and two air cleaners that actually worked. That's probably what you saw and assumed it was 2 carbs. There were problems with the carbs. When idling, very little air was pulled through each carburetor and they are touchy. There's just not much air passing through the carb at that speed. Although the fuel pump only produced 2 1/2 to 3 psi, this was too much pressure for most of the needle valves. As a result, most 6 cylinder carbs leak at low speed or just after the engine is stopped. Like someone else said, the leftover '54 and '55 Corvettes were slowly sold off. I owned a 1954 in 1955, and Chevrolet dealers were reluctant to sell a two passenger sports car with a plastic body. Cheers, Noland Adams, President Solid Axle Corvette Club this is why I was thinking 2 one barrel carbs...down draft...
I was also thinking down draft would work better at idle at lower manifold pressure than side draft carbs....????
Noland - we have never experienced leakage issues with these carbs, as long as the original Carter spring-loaded small orifice fuel valves were used. The commercial aftermarket rebuilding kits had/have a solid needle and too large an orifice. Jon
what about about direct carb to each intake.... and welding it to the header flange??? im still on the 2 v twin idea... like having 2 harley motors hooked to gether??? there gotta be some thing wrong with the fuel system to only make 10 hp.... does the combustion loose it's compression at the top because of the side opening flat head valves??? some times looking at a stock banger I think compression ratio is just a myth... with the compression getting bigger at the top..
I wanna try 2 WO style carbs....and I like the idea of 2 1 barrels... seems idle would be much better and cleaner...
