a friend brought a t-bucket over with this carb on a 355 melling mtc-1 cam (same as edelbrock performer 204 @ 050 int 214 @050 ex) and homemade zoomies. it loped and lean missed. I checked everything no vac leaks,elec issues,ect. to make a long story short this carb is just to lean to run with these headers. i put his carb on my old chevy truck 350,headers,same cam,ect, it idled fine! I put a 750 vac sec. holley (stock cal) on his car it idled fine and ran pretty good. to make sure I put my 1406 on his bucket,guess what same as his 1406,idled to lean and lean missed this carb must just be to lean for these big tube 3/4 inch zoomies,not best for this motor any way! i think he needs 5/8 headers with collectors to run this carb ,what do you all think?
