'84 GSL with '89 13B
 

Greetings!
I have taken over a family project started by my Uncle. So...I have an '84 GSL with a rebuilt '89 13B engine already dropped in it. What are my best options for carburetor and intake manifold? I have the original equipment but it does not match up. Also, my trusted drag racing friend is encouraging me to send off the carb to a trusted rebuild shop so I can eliminate one variable by knowing that the carb is not the culprit in any issues we have getting her running. Any recommended rebuild shops? Thanks in advance!
