1972 c10 307 carburetor options?

[JulioK]

My first post here so be gentle with me..

Recently bought this c10 and am really enjoying it! I'm told the carburetor is in need of replacement and it shows in poor throttle response. I am not interested in hyped up performance and really just want to have it accelerate from a stop smoothly and maximize mpg. It has a Rochester 7042105. Should I buy an identical replacement or look to another manufacturer? I'd rather not get in to changing the intake.
