Would there be much difficulty/excessive $$$ versus HP gain and performance to replace the stock 351W + 2vv carb with a stock or mildly modified Cleveland engine with 4 barrel - but reconnecting the extra police cooling stuff, switching to a distributor vs stock electronic firing module? I'd want to have it done in a N.San Diego County shop, as I don't do this stuff anymore.. mostly can tell if I'm being BS'd or not, 'fya know what I mean. Any info, tips, good area shops, etc will be appreciated. Thanks
