The hp ratings for a 351W is the same if carbureted or EFI. 210 hp but EFI made 10 more ft lbs 305 or 315. 2 other things you need to know in order to determine if it was running properly, 1 is rear axle ratio, and weight. The axle ration will determine engine speed and weight will determine how hard the engine will need work to move the van. 351w are not high rpm motors, and make peak power around 3000 rpm.
