I'm putting a stroker small block in a '69 Valiant, 360 block with a 4" crank, RHS heads, solid flat tappet cam, 10-1 compression, should make around 475hp, using a A500 trans, with its low first gear and a 3.73 rear set should be fun all around. The car will probably weigh 3300 I'm guessing?, manual steering and brakes, bench seat, 8.75 rear, Calvert bars and springs Pro Star wheels. Having the torque that the crank provides, light car, and easy to work on engine bay, (changing plugs etc), better handling than a BB due to weight on the nose, should be a fun car, maybe mid-11's and really driveable with the overdrive.
