67 Rambler - AMC Short Block Buildup

By , Photography by

There is a special sort of satisfaction that comes from showing a set of AMC taillights to the guy in the other lane. We've enjoyed that sensation as we've pulled the handle on the One-Two shift in front of a couple of slack-jawed M3 owners and watched them fade in the rearview. We did it using the Car Craft-tweaked 67 Rambler American built with all AMC parts. The car is distinct enough to get attention and familiar enough to prevent resentment, even if it did just hand you a loss. Chevy guys think it's a Nova, Ford guys think it's a Falcon, and Mopar guys know it as a distant cousin. Import guys don't know what's going on.

Using a base 360 we hauled from a junkyard and rebuilt at JMS Racing Engines in El Monte, California, the 67 Rambler American has run 11.50s in the quarter-mile, cruised to Vegas and San Diego, and wailed on any foreign or exotic car that cares to pick a fight. The original JMS Racing combo made 465 hp with off-the-shelf parts to prove that anyone with a torque wrench could repeat the effort. We've also been hoarding a set of Indy cylinder heads for close to four years with a thickheaded plan to build a 600hp pump gas destroyer. But first we had to find a transmission that would handle the load, build a rearend that wouldn't crack like a peanut, and assemble all the little parts that make a good AMC tick.
