Tunnel ram cam?!

The carbs you posted are not only too small, they are worthless.

You need a carb that you can tune. If you don’t know how to do it, or don’t want to do it, you need to buy custom prepped carbs so you are close enough at the start to make them work correctly. Two Pro Form 650’s without a choke is probably the best bang for the buck if you want to do it yourself.

Buy a custom cam from anyone you want. But I can promise you there are no good tunnel ram cams “off the shelf”.

The biggest mistakes guys make in TR stuff is the wrong cam and carbs. Cut corners there and you’ll have issues.

Your case is the perfect example of when a fast ramp is needed. If you aren’t comfortable with a fast ramp SFT you should consider a solid roller.

I won’t post specs because you need to get on the phone and TALK to as many cam grinders as you can. Take notes. Write down what they tell you for specs and compare them. You’ll quickly see the outliers on both sides.

I will say this...I’ve never seen an OE architecture TR engine want an LSA over 109. If they call out for an LSA wider than that, they didn’t use enough duration and are trying to crutch upper RPM power by opening up the LSA, which is a sure bottom/mid RPM power killer.

BTW, you didn’t mention what RPM you want to be shifting. That makes a difference.
