Hi All, maybe I should ask the 5.0 guys this question but there's a ton of experience in this group so I thought I'd pick your brains first. The engine for my 65 is based on a 1987 5.0HO block. I have just about all the parts to start building the motor including the distributor. When I bought the distributor (e-bay) I bought it from a seller who seems to have lots of experience. The distributor was advertised as being for 5.0 EFI to carb conversion where a 1/2" longer shaft is needed. Perfect!! When I started digging into my assembly manuals I did not see any reference to there being a difference in distributor shaft length for the 302 blocks. I know the 351 block is taller but couldn't see anything on the 302 needing the longer shaft. I re-checked with the seller and he says Ford did this on the later EFI blocks to improve the gear interface and that not to worry, I do have the correct distributor for a carb conversion on a 1987 5.0 block. So, after my long winded intro...are any of you familiar with this?
