351w problems

[mustang1969dust]

the motor acts as if it has no low end ,it wont even spin the tires, i belive its a carb problem maybe runnin to rich cause it acts like its loadin up ,it has a 270 cam,750 holley carb,edelbrock intake,msd ignition,bored 30 or 40 over,headers,dunno if any of that will help but anybody know what size jets the carb needs if its the problem thanks

Try 69 primary and maybe about a 72 secondary.
(I've had good luck with 351W and 69 jets up front for whatever reason)
