I am currently building a 66 chevelle which will have a big block in it once completed. I have a saginaw 4 speed, however, I have always planned on using a Muncie M20 or M21 for this project. Budget restraints have got me thinking about using the Saginaw for the time being until I can scrape up the cash to buy a freshly rebuilt Muncie. I know the M20 and M21's are a much better tranny, but how well will an old Saginaw hold up with a big block? Is it even worth considering or should I just wait to get the muncie?
