Hi,
I have a fairly new build carbureted 383 stroker that's pushing close to 600 hp on 93 octane, .that is starting to flutter/sputter at WOT and will actually shut down due to lack of fuel and I have to wait until the pump pressurizes and I pump the throttle and then starts right back up. does this hot or cold.
Its like the engine demand is sucking the carb. dry!???
I am running an Edelbrock 650 single line with a Holley 150 fuel pump and regulator that is brand new and is holding 8lbs of pressure at switch on and then maintains 4lbs at engine idle to 3000 rpms.
I recently cleaned all fuel lines and changed both fuel filters and their seems to be great flow.
I did find some fuel cell sponge residue in the fuel and then pulled and replaced the cell sponge after flushing the fuel lines.
air flow mixture is relatively stable sustaining 12.2 - 13.4 ratio.
it appears that all the vacuum hoses are fitted properly and not leaking and the timing appears to advance etc.. while accelerating.
I know this is a long post, but we are now totally lost as where to find the problem. Any Ideas???
Any help or recommendations would be appreciated
