RE: 116 cubic inch twin cam
The TW8 has been one my favourites. The 67's have slightly more duration with similar intake closing time so cylinder pressures will be similar at cranking and low speed but the 67 will build more pressurre at higher rpms due to increased cylinder fill, if the exhaust allows. Since your looking for tq vs hp I would recommend the TW8. Mechanical compression will have to be around 10.5 to get your 200lbs cranking pressure. The ticking is more about pinion runnout than the fast ramps. If you have more than .003 you'll have the tappet tick with either cam.
