This is my first time posting a thread on any website so please bare with me. I recently purchased three Studes that have been sitting for 30 plus years. I am restoring the 63 Avanti R2 and have learned that the block is cracked. The other two vehicles are a 1963 Daytona Wagon with what I am told is an Avanti motor (it has all the same chrome on the engine as the Avanti that I have. It also has a four speed on the column, front disc brakes and third row seat. The other is a 1962 Hawk GT with 289 and 4spd on the floor. All cars are very complete with little or no body damage. With the exception of the Hawk which has some rust in the trunk and damage to the drivers door. My questions are this; 1) What are the differences between a regular 289, an Avanti 289 and the R2. Are there any external visable differences (the wagon motor has chrome valve covers and valley pan and stainless plug wire covers at the block). The wagon has plug wire covers at the sides of the heads only and the Avanti has them at the back of the heads and up and over the distributor only. Are these correct or are they missing pieces. Are the blocks inter-changable and finally should I sacrafice the Hawk or the wagon for the block. Which one is worth more complete. I know it"s alot of questions but I am new at this so thanks. Anyone is welcome to call me as well. Stuart 866-333-2184
