Low speed torque and driveability ?

The whole thing I'm getting at is torque the main/whole culprit ? As most would say or is there other factors that play a huge or bigger role ?

Obviously what we consider driveability and what part of driving has a huge effect, cruising, passing, spirted driving, from stop to full throttle and cruising to full throttle are all different in what were exactly comparing.

Like you said earlier you find a xe268h cam a dog compared to stock 340 cam, your saying cause of loss of torque, I'm saying maybe, maybe part of it but I don't think so, all those dyno's I posted low end torque don't seem to be an issue, but were generally not seeing under 2000-3000 rpms so hard to say for sure, but if there is an issue I'd say it's probably other things which I was hoping to get to the bottom of.

If it is mainly a lack of torque that would be fine I just don't see how.

P.S. Aj say 340 cams have terrible bottom end :)


An engine needs very little hp most of the time.

At 1313 rpm hp is 25% of torque.

Tq. hp.
100 = 25
200 = 50
250 = 63
275 = 69
300 = 75
325 = 81
350 = 88

At 2626 rpm an engine need half the torque to make those hp numbers.
wtf does 1500 or 1800 have to do with anything?
the lowest stall is 1800 you are there for a milisecond
I could cruise my 243@50 cam no problem 1800 in drive 3.23s 26.99 L-60-14 stock verter
