Best of luck on the car hunt.
If you’re wanting a stock look, as per like what Chrysler did, the OEM carb and intake are very good pieces. What the stock engines are really missing is compression and a cam. Even with a low compression engine, going a step up in cam size can still make good power while retaining good street manners.
318WR has a good example where he just swapped out the OEM heads for speedmasters and reused the OEM iron 4bbl IIRC. Even without a lot of rear gear, he turned in some pretty good time slips at the track.
The SM heads is an easy way to gain a little compression. It’s not a lot and cam size can’t jump to much. But even a small change will do really well for power. The biggest secrecy to power is in the cylinder head. The better it flows, the less cam you need to get to the power goal or ET at the track.
Are you thinking of headers as well?
