Re: 520 Continental rebuild

The IO520 manual for the sandcast Block would be correct ,all O520"s were carb converted
as continental never produced a O520.

Re: 400 sbc build

By the looks of your current build, with the prop and reduction, you need to spin that motor to about 5200 to 5300 to get what you want. Looks like you need to change the cam ,heads and intake ,as far as cams go I've used the comp XM278H on several builds with good success ,eldebrock performer rpm h...

Re: A/V 200 removing headers without breaking studs

an old mechanic trick, heat the stud and put a candle to the stud ,the heat will draw the wax up into the threads, and act like a lubricant, he says they will come right off, never tried it though

Re: loss of power 454 need advice

cranking cylinder pressure is low even @ 140#. Did you have the carb throttle plates open when cranking? I would think on a direct drive piece 175# cranking cylinder pressure would be an absolute minimum. JMO- I'm with you on this one fish, this sounds like a flat cam ,or bad valve springs, had a s...

Re: timing and vacuum advance

Deano ,while I will agree with part of your statements ,we should clarify that lightly loaded engine should be referred to as reduced load, anytime the engine is under full throttle load, which would produce little or no vacuum, in the same instance when the engine is running under any reduced power...

Re: Shutdown proceedure for IO520

Fuel would absolutely make the engine run backwards! The shut down procedure for an airplane isn't always practical for an airboat. For example you are idling up to other boats or a dock and you want to stop close. You can't pull a lean cable and wait for the engine to shut down. Wether it be prope...

Re: Shutdown proceedure for IO520

Proper shutdown, pull rich lean cable to full lean ,after engine quits both mag switches to off( grounded) if engine tries to run on or diesel after going to full lean , its an adjustment problem at the barrel valve,(fuel not getting completely shut off) on a side note fuel octane would have nothing...
