Time to add some inexpensive HP

Okay, time to look for some performance gains.
Car has a bone stock ’73 318 with Carter BBD 2 bbl.

I’ve done my Forabodiesonly/internet research and am planning on putting on the basics:
- Upgraded intake manifold
- 4 bbl carb
- 340 exhaust manifolds (I’ve already got in a box)
- dual exhaust.

Question: what intake manifold causes the fewest headaches. This car is going to be driven on the street and I’m not looking for racing performance, just a platform to put on a new carb.

Are there any good, not-too-expensive intake+carb combinations I can bolt on? Bonus if I don’t have to replace all the throttle and kick-down linkages.

Not going to do a cam just yet. Down the road I may consider a 340 cam.

(I’m familiar with Carter after having rebuilt mine)

Thanks in advance.
