Not all donor cars are created equal; some aren’t even cars. Some donors are 1986 GMC motorhomes; 1986 GMC motorhomes with 454ci big-block motors that put out a massive 480 ft-lb of torque before they’re even touched.

Now, with only a team of professional techs and the backing of a major auto-blog you can take that monster to an insane level of horsepower, 560 hp to be exact.

So go out and find a big block, a beater to put it in, and flourish. Make you’re inner gearhead happy.
