If you really want to party and have the heads to handle it, tw-68 with some compression... tq dip is from the max effort exhaust system.

They scale right up the ladder when you have heads that are working and adequate V to V. No favorite cams, just a few that would work, but there are a few that are just plain stupid mainly due to LSA and/or LC. And I prefer <.630 lift so that a reasonable valve spring can be used and take the lifter, weak link, out a little further as a maintenance item. This is why I prefer 7mm valves and a light spring package, same philosophy. In this case the zoomie pipe that looks like it should have the credentials on paper does not pan out. Any of the cams mentioned in this thread will work well, all of them with compression adjusted. Me personally I prefer a little less of a hard hit right off idle and stronger top end pull, can make that happen easy enough too. I ran the TW408 in a bike at 11:1 and 117", hated it. Hot running SOB that had terrible off idle manners and it came on super quick and died the same. Low speed reversion, tune was spot on too. Not a statement on the brand name, notice I recommended a Wood cam above. It is all in the numbers.

How about the CR630i? It  seems to fit your above description?

Sure it's a contender if the balance of the mating parts of the assembly cooperate.

How's the Bassani B1 pipe?

SE 266 works super well with good compression. They will surprise you.

The pipe? Depends on what it is paired with, they are popular.

The B1 Paired with a build like this and a cam in the range we are discussing.

There is a set of 266 cams for sale on flea bay currently... $120 not much waisted if you don't like um 👍.

Moderators, these are not mine to sell, I'm not trying to sell or advertise a product. Just helping the OP out.

Same bike pipe cam and all, just a different end cap. Custom pipe on a 120.

Going from a Thunder header to a Boarzilla on my old 107 took away the dip and I gained 7hp on top.
I'm not here cause of a path before me, Im here cause of the burnout left behind
