Yes you CAN do a billet crank with an 8-bolt flange, but really the later crank with a pushbutton 727 is a MUCH better idea!
The MP 4" stroke crank (P.N. 5007256) fits in your poly 318 and is only $349 ready to use!
You have to use a '62-64 pushbutton A-engine 727 (or a '65 A-727 with a '62-64 pushbutton valve body swapped in), BUT this is a great idea.
1. It weighs 65 lbs. less than your A-413 cast iron Torqueflite.
2. It uses 10-15 less horsepower than the A-413. (10-15 more HP at the output shaft)
3. It's easier to get parts for!
4. It shifts with your '57-61 dashboard pushbuttons. The cable hooks right up!
5. A guy building a Max Wedge clone will be only too happy to get the A-727 he can't use out of his garage, several of us have grabbed good A-727 pushbutton trannies for FREE (!!!) from them! Even if you're not in the right place at the right time,the A-727 is still a relatively easy and cheap find.
Just my 2¢ worth....
