Since Jeep used Buick 225 V-6 and 350 V-8 engines in some models, Buick, Olds, Pontiac, and Cadillac engines can mate to some Jeep transmissions rather easily. For torque kings, look for the ’60s and ’70s land yachts. Although the 350hp/510lb-ft 455 was already gone from this ’70 Buick LeSabre, the ’66 Olds 98 next to it was still sporting its 310hp “Super Rocket” 425 big-block. For Buick, the engine displacement is cast into the back of the block between the intake and bellhousing. For Oldsmobile, check the cylinder heads for either a big cast letter or number. Letters are for big-blocks and numbers are for small-blocks.
