DV.. definitely want to go with a hr this time..
re- cjp
there are correct events that will tailor a combo to suit a usage, for a given combo, the cam that gives the sharpest tq curve is not the cam that will provide the best rpm past peak potential.
Ok, I get that..
you may have to give up something somewhere to achieve the desired goal. But by the same token how much and where gets pretty important on a daily driver. Knowing where peak tq and hp is would be a good starting point. Then there is no substitute for experience imo. The more of these combinations one has built and or driven the more feel you get for what does what.
re-
And there are a multitude of other reasons for altered events/lobes, ie, differences in exhaust system shape length is just one, for a combo always running open headers, would you say the cam optimal in that was the same as the cam for a full exhaust, or a boat?
If someone had some experience with and had chosen all of the other parts they knew they wanted to run for a specific usage, would there then not be one set of correct cam events and therefore one best lsa? Maybe its the goal that needs to be defined more accurately in order to find that one best set of events including lsa?
If you're liking more lsa then id say this is because you are less caught up in the pose value of the cam/engine sound and more preferring the better idle quality, smoother low end etc?
For sure, I've got old racer friends who have almost totally lost hearing now. All that noise and stall converter kick, rough idle rocking etc has lost its appeal for me. I'm way more a sleeper sort of driver now. I'd call it wanting a more "spirited daily driver" as opposed a street strip. Make it like a smooth factory idle but add as much in as possible when the pedal goes down further. I stick mainly to na now but have a vortec centrifugal charger and a few favourite turbo's still kicking around should the urge hit again.. However, with age, price and simplicity weigh heavier and the longevity of ones daily driver is also a consideration. I'd love to have a nice dependable "daily driver" parked outside the old folks home when I get there. I'll quietly idle away in the mornings and they'll never know any different and hopefully never take my license away.
