A 318 will do well over 100mph in a Valiant. I had my dads Fury to 112 with a 318.
if i recall if the chase seen was real the spedo was on 110 slanty cant move the spedo that quick up there sounded like 318 to meI'm betting that it was a slant six in that Valiant.
i think there is a shot of that i would have laughed if it had a slantyI haven't seen it in a long time, but don't we get a look under hood because it's overheating? Planning to watch and find out for myself.
