As you can see those ports are AS CAST!

Setup:

F-Body, 402 Cubes, DANA 60 (3.73), 11.1:1, Dart 225cc Heads, T4P Stage 1 "Porting", 2.02"/1.55" valves, PAC 1521 Springs, B-Spec 402 cam, M/T Drag Radials, 4L60E, 3600 Stall (Locked), 1 7/8 American Racing Headers, THRU CATS!!!! No electric water pump, no aftermarket rockers........ and tuning by Wiggans Performance.

Remember guys we don't have a dyno to make this stuff lie (cough.... Vengence, TSP, etc...) William @ Wiggans Performance buys these packages because he knows they make power, he is a dealer because he knows they make power and we know he can make them run!

FWIW you can only get the T4P heads and B-Spec cams thru Bauer Racing Engines or authorized dealers.

Here is another comparison, this time in a LS2 (6.0L) GTO with a M6

Blue = Dart 225cc T4P Valve Job Heads (no porting), Kooks Headers, Ported FAST 90mm intake and a my special sauce 224° cam. Customer wanted a daily driver setup.

Red = AFR 225cc heads, American Racing Headers, LS2 intake, and a nastier 230° cam from me that gives good results.

So similar cars, same dyno, same tuner to take the variables away.
A different dyno or leaner tune would change too many variables, as William found out lately when a car he dynoed picked up 20rwhp over on a different dynojet.

Almost looks like the motor is just 25 cubes bigger don't it? As I always say, the heads are what moves the TQ curve up and down the scale on the left, the cam just changes the shape of it.

Here is the idle of the T4P Dart car, the idle tables are stock and the customer is really happy with how well the car drives, as he says "drives better than stock!"

Those are some scary impressive numbers!
Why can't they work on LT1s.... :(

There are some Dart 200cc and 215cc LT heads out now... we are playing with the 200cc heads to try some similar stuff. I wish the rest of the LT was as good as the LS!
