4bbl/linkage questions

well the research i did was factory parts books. that might be harder now days. it helps to be in good with a sharp parts man. the parts book for the year you are working on will tell you that a 318 2 bbl has a diff bracket than a 4 bbl on the same engine / year. a large batch of old parts books would be worth a ton of money. the MOST important thing about carb swaps is to be sure the throttle does NOT jam WOT. if you over rev a stock chrysler engine it WILL wipe out the piston ring. NEVER NEVER NEVER push a stock chrysler engine more than 500 RPM over top rated RPM.
