  • 1963 Hawk

    I recently bought a1963 Hawk, the previous owner told me that it had a special motor that was used with 4 speed manual transmission,BUT he had no documentation on the matter, is there any way I can determine what the engine is,is it a 289 or a 307 as he advised me.

    Others here can take your numbers and tell you the original equipment, but I can say with certainty no production Hawks came with 307. Only possibilities are 259 or 289.

      Check the serial number on the engine. If it is what he says it is the serial number will begin with "JT_ _ _ _ _"
      Probably would be a 289 cui. There were a few R3 and R4 engines produced that were 304 cui.

        If it is Avanti powered the engine # stamped on a pad beside thermostate housing should begin with a JT(jet thrust)if a regular 289 the # should start with a "P".Some of the JT engines were supercharged,if you post vin # somebody on here will be able to tell you how it left the factory.

          Welcome to our world. 4 speed transmissions were available with all engines. Get us a serial number from the engine and we can help determine what it is. The S/N is located on top of the block just in front of and to the left of the valley cover. Use the search function of this forum and go to the SDC home page for directions to a wealth of information

            To; billjharris,---- Sending to the SNM for the car's production order is probably the best way to go in this case. Good luck!

              The engine number is stamped on the l/f of the engine (drivers side in North America). The number seen on the right side is a casting number. A minor correction to fpstude's post is 4 speeds were available with all V-8 engines (n/a with 6 cylinders just in case there might be a misunderstanding with someone reading this in the future). Your car came standard with the 289. The "Jet Thrust" Avanti engine was available in your 63 Hawk. As kmul221 pointed out that engine would have stamped JT (for an R-1 engine) or JTS (for an R-2 supercharged engine).

              The production order from the SNM will tell how the car was equipped when it left the factory, engine #, even key codes!

                There were no production R3 or R4 engined Hawks manufactured, so that let's the 304.5 out. There is even question that they were available in 63 model Hawks. They were an option for 64, but none were ordered. Bet some folks wish they had now...

                Now, if someone rebuilt it with huge overbore or stroked it, that's a different matter.

                  Now why would anyone do that?
