I'm looking to pull the old and tired 239 out within a few weeks. I picked up a 61 292 from a f1oo over the winter. I know the bell housings are different so im going to have to change those swap them. Its a 3 speed car and the newer motor is a 3 speed too. Im just wondering if there is any troubles or problems I can look forward to when swapping them. I also need some exhaust advice. I want to get rid of my cross over and put some headers in. Does anyone know who I should go to for that. I was thinking of checking out reds headers but I dont know if having a 54 with a newer motor will cause problems. Any help will be appreciated. Thanks gang.
