I'll be honest, Im not a big fan of the convertor , IMO takes far too much throttle to get it moving, especially cold.


We did 1 3/4" headers and they work fine on my 505. I also use a 2800 rated 11" stall converter that works great with a 3.54 gear.

You really should have some type of head work done to take advantage of the larger stroke. I tried using an 8 3/4 and broke it in short order. Put a Dana or 9" in and never look back.
