The race superiority of the 250 here in Brazil as the best and the
fastest race and stock cars has been awesome for about 30 years. Why?
Because the Opala came with this engine and was faster than Ford Mavericks
302 V8, Dodge Chargers 318 V8, etc. The car was lighter, with better weight
distribution, very good brakes and was smaller and lower. I have some
old pics of Opalas in races here, with 300-400hp in the mid 70's, with the 3
Weber power pack, etc. We do wild modifications here. The
fastest 250 engine car ever is the "Yellow Black Lethal" - yeah,
it's a Opala. You can Google search to see it. It ran a 1200hp
250 L6 engine for many years. Wow! Extremely fast.
I'm planning to put in my car an EFI system just about the end of the
year - I'm almost a Electrical and Electronic Engineer and I'm going to
build a EFI for the car.
