i have a PCM chevy 454 engine with holley 4 barrel carb that needs a re-building. the kit plus someone to help me re-build and then tune it will cost around $150 give or take a few. a new edelbrock marine carb runs about $300 shipped.<br /><br />i never really had any 'problems' with the holley but i don't really know that it was running properly. the holley came with it when i bought it a few years ago. i've always had some smoke on start-up and a little sheen on the water when starting cold.<br /><br />so, i'm thinking of switching to the edelbrock and am interested in hearing about past experiences with making this change and with running an edelbrock carb.<br /><br />thanks
