As far as i know, the silvertop and blacktop are almost identical. Advantages and disadvantages are really up to how look at it and use it, they're both superb engines btw
However, common differences are:
- Silvertop/Svt uses AFM (Airflow meter, flap type) while Blacktop/BT uses MAP Sensor (or vacum sensor).
- Svt internals are thicker (n a bit heavier) then BT, which is lightened.
- Intakes inlets n exhausts outlets on the BT heads are bigger compared to Svt.
- Both comes with VVT (intake side only). Svt compression is 10.5:1 while BT is 11:1
- Svt pumps out 160hp @ 7500rpm (62 Nm @ 5200rpm of torque), the Bt on the other hand
generates 170 hp @ 7800 rpm w (162 Nm @ 5200 rpm of torque).
If your planning to go for turbocharging or any force induction upgrade in the future, the Svt is better due to it's thicker internal/moving parts. The BT is better suited for NA tuning.
* If i made any mistakes above feel free to correct it
To me i find the Svt's AFM is a hinderance to upgrade my air filter and uses up space (also cant use velocity stacks or trumpets since u need the AFM to run the engine. The BT on the otherhand, i find that the thin internals are a bit to small for my taste.
