Over the winter, I added a TW8-6 Woods cam with these mods: SE 10.5:1 pistons, heads ported, 5 angle valve job, heads decked .040", cylinders decked .010", .030" head gasket;and a Zippers 3" air cleaner, 110 OEM induction module. I'm also running the D&D 2:1 factcat.
Just swapped out the TW8-6 cam for TW400-6 cam. Dyno results shown below, stock, to the 8-6 to the 400-6 (they show from bottom to top, in that order.) The 8-6 came on strong at about 3200, but the 400-6 has more power sooner and carries across a broader range. It's got some noise to it, but it doesn't bother me. We added roller lifters with the 400-6. The 400-6 really seemed to open up the engine and tap into more of the power I expected from the mods. I'm pleased, but I'm learning as I go. This engine mod business has a lot to it, there's no right answer, and like the rest of the CVO experience, it's personal.
The results, in order from bottom to top, are the stock cam, the TW8-6 cam and the 400-6 cam.
