The intake manifold on my car is a factory DeTomaso Weber manifold, built by Holman Moody for their racing team. These manifolds were very thin and prone to break so only about 16 were made. Pantera racer, Hugh Kleinpeter, from whom this manifold was bought in 1976, indicated that only four made it to the US. He had it machined to keep it from cracking, and I've had it on and off my car for 45 years without problems.
