I wish somwbody would give you an answer here, I want to hear the answers too. I am just looking a buying a 67, 7eca and it had a 0235 in it but the engine dont come with the project. I found a 0235c engine that is rated at 100 hp and only 6.5 to 1 compression. I want to know it this engine can be modified to legally put into the 7eca. I also have a 0320 and a 0290d from tripacers and could use them if they would be legal.
Thanks,
tomt
