I recently acquired a 63 Impala SS with a 408 stroker. It's a complete frame up restoration. I traded it for my 66 Shelby Cobra replica that I built 17 years ago. My wife has been bugging me to get a car with a roof and windows so I pulled the trigger. I found this car in PA and traded for the Chevy and some cash to me. Took it to a show today and won best 60's car.
Is that a W' Block (348) bored and stroked to make a 408/409? Or a four inch bore 350 really bored and really stroked, or a just bored out 400 SBC, or maybe a bored 396 block? There are a lot of ways to build an engine around that cubic inch displacement.
