Holden 6 cylinder black and blue motor with 12 port cylinder head.
The Blue motor 2850 and 3.3 litre engine as well as 202 or 3.3L black motor inlet manifold to suit Holley 350 and 500 2 barrel carburettors.
Our testing has found the manifold performs better as common runner rather than using a divided inlet port runner like the factory Varijet manifold.
When you want the chrome or highly polished look from a thermal coating preparation is the key, the better the preparation the better the finish.
Ceramic coatings not only look nice, the are much easier to keep looking good.
The manifold has one x 1/4 NPT vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting.
