Ok built new 451 stroker motor all new build ported 452 heads with over sized stainless valves 10:1 230 dur cam street car motor automatic its in a 32 plym for old school look went with dual quads two used 1406 600 cfm edel carbs offenhouser 360 dual quad manifold and eddelbrock progressive linkage. Carbs were used on another motor with dual quads have no idea what that person used them on. my motor lean as hell took carbs apart cleaned and checked over found the jets are way lean have no idea why but eddelbrock stock sizes are 100 prim and 95 sec with a 6547 rod these have 88 pri and 77 sec with 7157 rod not sure why these are setup this way but front and rear carbs have same setup. Does anyone have any suggestions for jetting before I spend a ton of time tunning. or should I go with eddy specs? motor should have about 14 in vac at idle. second question do you setup dual quads front and rear same or due to progressive linkage change that?

I think I would start where Eldelbrock had them.
