what are you guys running for timing 32 or what

We would need quite a bit more info than that. CR, fuel type, etc.

Why is this in the dyno section?

408 11.5 compression, dart ported 225s ported by larry meaux, fast 102 ported by mamo, tsp giant cam, a4 3600 vigilante, nine inch 410s, fast 92 t/b,42lb injectors

Cause it dynoed 445/399 that's very low, trying to find out whats going on

Unlocked with timing at 23

The cam is too big or not right for that setup. Just because it is a huge cam doesnt mean itll make huge power.

It also depends on what the tuner set the afr to. That setup should like 12:7 to 12:4 ideally. But you have to change the timing first as any jump of a few degrees will change the afr significantly. That one should ramp in from 23-27 or 28 max. It could take more than that but not sure I would run it on the street with the variance in fuel quality.

It's not the cam his is a little bigger then mine and has ported 225s but is auto. What kind of dyno is this on

Dynojet

Those 4.10 gears are going to rob some power, too, on a dyno.

Not as much as you would think. If you had a better spec'd cam you would see an increase no matter what. Proper cam > donkey dick

450rwhp is not bad for a big stall and 9" high gears. 408s don't make that much more power than 364s, just a lot more torque.

I think you are way wrong on that one. My friend has one making 525 horse to the wheels. Lets see a 6.0 do that.

I see a lot on 408 on here making 500 with the same heads and cam and stall but my 399 torque that's low

Here you go big boy, all making over 500rwhp.

Even 347s are getting close:

Anymore questions?

Yah, why waste time just to try to prove me wrong? All those cams are way larger than his. And AFR heads to stock castings are no comparison either as well as the PRC new castings. Also the "cam only" ls2 wasn't cam only and had a fast 102 etc etc. And to make a 347 do that, you sure cannot drive in a parking lot. I can point out all the differences, but instead of asking me his combo you just want to prove me wrong first off.

Any questions now?

my pump gas 408ci 11.1cr with a TX giant cam was set to 29 total timing.

from what ive seen with an auto 490-525 hp and 400-475 tq with a 225 head be it afr or dart. whats the exhaust on this car and cold air intake.. and a dyno graph if you can..

gectek a 6.0 ls2 will not make what a 408 or 40x makes lol thats just stupid talk, my cam is a little smaller 247/251 on 112 although im m6 i dont see any 364 ls2's near me lol

Blackbirds what was the horsepower and torque

gectek

iTrader: (2)

Well there is always some a hole that comes along to try to prove you wrong. Apples to Microsoft I say.

I like torque in general, so keep the CR high, Have a good amount of timing, and keep the cam correct. You will be happier with a few less peak HP but higher overall avg tq.
