383 Questions

The 383 and 426 share the same bore of 4.25,
the difference is the stroke 3.38 (383) 3.75 (426).
There really is no reason to mess with Hemi heads
as you can make the wedges run good. The cleanest
stroker is to put the 426/440 crank into the 383. There
are several companies selling stroker kits: 440source,
muscle motors, hughes and Indy.
What are your intentions; Street, street/strip or all
out strip? That really will dictate what to do with the
engine. Several guys on here can tell you combo's ,
BJR racing, moper and 383man off the top of my head
I can think of.
But they will need to know all about your intentions
and type of vehicle you would put the engine in.
