I am installing an Edlbrock Thunder series carb on a 1974 Plymouth Cudawith a 360. The carb will not seat because it is hitting a vaccuum port on the left(drivers side) of the intake manifold(stock). I am already using the spacer plate that was under the stock carb. Not sure if I need an additional adapter plate or if I need to change intakes. Money is tight. How do I fix this??
could this be the EGR valve you are HITTING????its on the drivers side on that.. for GM applications.. there are offset adaptors for the EGR valve...i could not find anything for the dodge..if you bought the carb new.. call edelbrock tech support..see what they have to help.. you.perhaps some of the other forum members have run into a similar issue..what ever you do.. please drain the gas out of your factory carb... shake it out.. let it air dry and stick it in a plastic bag thats tied and shove it in a box.. you might find at some time you will want to return it to service after an rebuild.. a thermoquad for a 71 is listed on fleabay for 400 bucks.. used..since your car has an Thermoquad.. going to a thunder is just a step sideways..
Summit sells a rebuilt thermoquad for $270.00.
