Dart makes a 351 block that can be boreed/stroked to 454 inches.
i am putting a 351w in my 85 Crown vic as opposed to the stock 302, i need the torque over the 100# of weight savings, the car weighs around 4000#. My next engine will most likely be a DSS 396, although id really like to go 429/460 but id need to find a Torino to serve as a donor car, that and the cost to modify it will be substantially more.
