I have to disagree with this, my buddy has one of them big cams with a fast 102 so his peak power is around 6400 with a 4400 stall and he has played the gap band for them small cam car guys that like to rag on people with "donkey dick cams" lol

 

Its possible. Just because someone has a small cam doesnt mean his car is set up right either

 

Thanks for all the feedback guys. It has a little over 98k miles. Dyno'd 350 hp 350 tq last time it was tuned years ago. But it trapped 110 mph in the quarter, full weight, street tires with my fat *** in it, lol.

 

I have a smallish BTR stage 2 227/234 and it peaks at about 6250 rpm but has nice mid range torque. I'd venture a guess that with gears, stall and auto the larger cam would probably be a bit faster due to quicker shifting. But I'd also venture a guess that the smaller cam is more enjoyable to drive overall.

 

I have a cam motion 233/241 and tfs 220 as casts. Compared to my old setup using stock 243s and an ls6 cam the midrange and topend are explosive. Using the same 285 40 17 nitto 555 g2s i couldnt utilize the new power until 3rd gear/over 75mph and have to run a drag radial now even with suspension setup for max weight transfer. The ls6 topend made great power, i loved it and had it for years. Car ran a 10.84 @ 125 @ 3370lbs back then. Put down 415 on a mustang dyno threw a 9" after the fast 102 upgrade with out any tuning, it was very lean. Keep in mind i reused my fast 102, 1 7/8 headers, 104mm lid etc, even using the same 4.30 gears (t56 car). Literally the only things i changed a
were the heads, the cam, lifters, pushrods, went back to stock rockers instead of the yella terra 1.8s, valve springs, 340 pump and obviously the tune. My injector duty cycle has gone up 10% since the change with the same target wot afr as before. These are 42lb ls3 injectors and 63psi of fuel pressure with the 340 pump compared to stock 58psi, they are peaking at 98%. The only downside now is under 2000rpm the power difference there is undeniable but this does not make the car drive bad. It has no issue maintaining speed on the highway in 6th gear even at 1500rpm, there is plenty of power to accelerate just not as much as before. I was able to tune out cam surge by reducing timing from 1400 to 1800 rpm. Both setups i have daily driven up to 1000 miles a week for long periods of time. The both are very similar on fuel with a slight advantage to the ls6 setup, this of course assuming sane driving. No doubt under heavy throttle the current setup will drink more fuel. I see alot of people say drivability will suffer well i can say ive gone from one extreme (stock heads and cam) to another (big cam and big heads) and id pick my current setup any day of the week over what i used to have. The trade off isnt drivability if the tuning is done right and the car is setup properly. The trade off in my situation is less power under 2000 rpm which does not bother me at all but on the other hand there is a big gain in performance from 3500 on up. The car is flat out way more fun to drive then before, the power is very impressive.

There are always going to be trade offs, even with a small cam. For instance a stock ls1 (smaller heads, less compression, smaller cam) is snappier and has the same midrange and more lowend torque than a stock ls6. But an ls1 makes makes 50 less tq and 50 less hp at peak rpms. Ive had both and with the right gears / converter you wont even notice the difference under the curve with the ls6 and in a drag race the ls1 wont stand a chance. Even on a road course the ls6 is preferred.

 

I think comparing M6 vs auto setups is comparing apples to oranges. M6 guys aren't dumping the clutch at 3600 rpm at every red light.

 

Whos comparing m6 to a4? Have you ever driven an automatic car with a quality 3600 converter?

 

A quality converter dose not couple at its rated stall speed under light throttle. It is a viscous coupling with a non linear stall raiting vs power input.

 

I didn't know that. I wondered how people were living with such high stall speeds. It was explained to me that a stall revs up to the stall speed upon acceleration.
