1961 Dart Hemi

"My master cylinder has a bigger piston than your engine" LOL

About 150 cid. Wonder what the bore and stroke is?

says...................

bore 76mm x stroke 70mm

So about 3" bore X 2 3/4" stroke!!!!

Wiki ALSO says!!!!

The original A-spec version could do 120 mph (193 km/h), but the chassis, a “14-gauge ladder frame with cruciform bracing” based on the Triumph TR3, flexed so much that doors came open, marring its reputation.
