This motor came out of a 1982 turbo regal hot air car. I dont know the story behind it but it has ARP rod bolts, turbo crank and turbo harmonic balancer, aftermarket Mallory HEI distibutor. Exhaust ports appear smooth, not sure if the heads are ported. Motor comes as in pictures minus the oil pan. Should make someone a good starting point for their build. Im asking $400 obo. PM me for any questions.
