Hey whats up? I am just beginning a build-up of a 67 Mustang convertible. It has a late model rebuilt 302 and I am told it has the original 289 heads on the rebuilt 302. It has a C6 tranny and stock rearend. I am planning on using the 302 in the car and this is where my questions start. I am fairly new to Fords and I do not know how to identify what year range the engine is to buy parts. All I know from previous owner is that it is a later model 302 very recently rebuilt. Are there specific serial numbers on the block I can read and possibly take to a dealership to identify the year? I am planning on a healthy cam, fairly inexpensive aluminum heads, and an Edelbrock ProFlow multipoint EFI set-up. I want to reuse as many of the current engine components as possible to keep costs down as this is definitely a budget project. I am not completely decided on auto Vs. manual trans but will probably end up going with an AOD. Any input on trans crossmembers? Can I reuse the original crossmember if its modified? I am assuming the AOD would be longer than the C6 but surely that is a popular conversion. Thanks for all help and I'm sure I'll have a lot more questions in the future.
