Pontiac Ram Air 5 tunnel port Billet Cylinder Heads.
I built this pair of Pontiac Ram Air 5 Tunnel Port Billet Cylinder Heads.
These Heads are built for a 1970 Vintage Top Fuel 1970 Firebird Funny Car.
The customer supplied a complete C.A.D. drawing.
These Billet Cyl. Heads use the original intake and ex. Ports.
Supercharged Nitro engines require large Comb chambers.
Our Billet Alum. Tunnel Port Cyl. Heads have huge Comb chambers.
Today, we can build a 2- piece-water-cooled Ram Air 5 Cyl Head.
Sadly, Today, you can buy alum. Ram Air 5 Cyl. Head. Castings.
The original Ram Air 5 intake/ ex. manifolds and valve covers fit this Billet Cyl. Head.
I have the blueprints for the 389/421 Pontiac Cyl. Head.
I also have the 392 Hemi and the Ford 427 SOHC. Cyl. Head Blueprints. Please check out our nostalgia engine category. What can I build for you?
