Sorry, I was distracted. Thanks for the post letting me know I screwed up.
The cam below is used with 1.6 rockers in the TF heads.
I tend to like these small duration camshafts for a everyday usage hot rod since very little to no extra stall is required for use though the benefit of extra stall is obvious.
The car is an absolute driver. While the 3.55 gets on 26 inch tires isn’t very quick at the track or a major monster on the street, it does have what seems to be a very long power band. When you’re used to 4.10’s and up, it feels like the car has a super high jump to the next time it is ready for a gear change.
If I was looking for a max return on the camshaft in the 1/4 mile, I would need a pretty big jump up from 3.55’s! That’s not such a happy thing on the street.

Being your heads are well done considering the flow/lift specs you have given, I don’t think power will be the issue. I think you’ll get it.
I have faith in the 6 pack set up. As well as better drivability over the single 4bbl because of the carbs size. Much of this of course is also gear and converter related and will relief the engines/carb low speed complications that can occur. The other issue is tuning not just the mix but timing when the outboards come in.
In various tests throughout the years from various sources, the Chrysler 6 pack has seemed to perform super well against the ROM & single 4bbl set up. The design in the runners are a bit tricky and convoluted to be top end superior in all cases but has non the less darn near identical dyno numbers.
A RPM and a single 4bbl is the best, easiest, less complex and of course, IF you don’t have he 6 pack already, cheapest way to do it. Basically you do a 6 pack because you want to.
For better results on the 6 pack, look into not just port matching & as deep as you can go but, with special attention to the very low runners (like number 3) but also under the carb. The entrance way is normally not all that great and rough to which it can be opened up to at least the butterfly size though larger may show no real win.
Overall, your first post combo is pretty good IMO and should be just fine overall. 6 pack or 4bbl.
