Not best, but optimum Transmission?

my engine
is nothing special.
4.04x3.58 KB 107s at .005 out of the hole. OOTB Aluminum heads, with .039FelPros making 10.95 Scr and .034Quench. Adjustable valve gear, Airgap and ancient 750DP. TTI headers and dual full-length TTI 3" mandrel-bent pipes.
The cam I was most happy with was a Hughes HE2430AL spec'd at
270/276/110 +2/53overlap(52effective)/116comp/110powr/Ica of 64*
.050s of 223/230; lifts of 538/549
The current cam is a Hughes HE 3037AL
276/286/110+2/61overlap(60 effective)/114comp/105powr/Ica of 66*
.050s of 230/237; lifts of .549/.471
This cam lost low-rpm torque, which I solved with the Commando box.
This cam makes lousy fuel mileage as compared to the previous one; Which I solved by retiring it from being a DD. Now I could care less how much fuel it burns; actually the more the better,lol.
This cam puts a lil top-end rush back, which I missed after retiring the first cam,which was the 292/292/108.
Otherwise the midrange seems about even
If you can, run a cross-over pipe; I lost quite a bit of low-rpm torque when I had to cut mine out to fit the GVod.
Knowing what I have come to learn from the FABO gang, my next cam will be a Solid lifter, tight-lash FT with a really tight LSA to work with my GV splitter. But maybe only same after lash specs as the current cam, or perhaps one size smaller.
