Pre 81 block Dipstick, timing cover and Pan question

[rwhite65]

I used a 77 or so on the 91 block, and have used a 65 model before. They will bolt up, but as you already noted, u are gonna have to play with the dip stick a little and may or may not have to worry about the fuel pump depending on ur set-up.

Why do you want to relocate ur dip stick if already have a late model oil pan? If I read ur post correctly, why not use the 77 cover and just plug the hole off? That is what I did on a 408w swap this summer.
