I'd bet that the engine in that Falcon was a 7 main bearing 200 c.i. engine, because the 250 c.i. - 7 main bearing block had serious problems for oval racing. The 250's taller deck and longer stroke are a disadvantage because they limit revs. Risk of engine failure becomes higher with the 250. Aside from the seven main bearing design, the 200ci six is virtually identical to the 144 and 170ci sixes. Which alleviates clearance problems with the hood on a 60-63 Ford Falcon. Tha 250/300 series went into big Fords, trucks and vans....lots of torque, but tha highest I ever heard of one of these engines run was 7,000 rpm and into dangerous break tha rods territory....they also had problems with tha timing gears, IIRC that camshaft gear was a fiber gear...so ifn yu spun that gear at high rpms....chunks...... my Dad's F-150/240 spun it's cam gear twice....luckily at low rpms...engine just went whuff...and we coasted to a stop.
