I have to agree with FMX(for once) Get youself a 4.0L from a jeep cherokee or even better a 300 ford. Gobs of torque from the 300 and almost 200 ponies from the 4L and at least 220 ft-lbs. However, the 455 from the 76 Cutlass wouldnt be too bad. Granted, its a big block, but its an Olds big block. How many T-buckets see oldsmobile motors? But if you go with the 300, grab the 4speed with OD. Just to watch people go "huh?" If you grab the 4L, get the auto with OD. The manual chrysler trannies are garbage.
