Going to put A 6.4 for into my 92 Ramcharger for an everyday ride. Wanting to keep the factory computer for decent mileage, using Hotwire Auto for the factory computer.

A few questions:
Which would be the best choice for buying a junkyard motor.? I know the Challenger has the lower alternator Mount and the truck is higher. I would like the extra HP of the challenger but I know that the frame needs notched when using the challenger accessory drive.

When it comes down to actual money which is the best buy? Can I buy the truck motor for a little less money and get the front accessory drives still put a challenger cam in it to get the horsepower. Or just buy the Challenger take out and buy a truck front drive?

Any suggestions on where to buy the 2014 and up take out truck Motors?

Thanks
