HP2,
I have been contemplated a stroker build for a 383 (Hence why I clicked on this thread), but for a street driven engine it just doesn't seem to make sense.
440source.com Stroker Kit ~ $2250
Gasket, Bearings, Cleaning Engine ~ $500
With the limitations listed above you seem like you would be better off to:
$1000 440Source.com heads or $1200 for Edelbrock E-Street (Get the 72CC Head and bump up the compression)
$300 Thumpr type cam, give your self low down power and sound!
* I Would lean towards a Comp 274 myself, but I know the Hughs Whiplash and Thumpr types are popular on stock bottom ends.
$500 Headers! Ditch those Manifolds
$500 Converter, ship it to a builder to have it made for your application
Note: Edelbrock RPM manifold, don't even look at another. This is been proven time and again in the forum.
I honestly believe the above go-fast parts would make a faster car than putting every dime in a stroker kit and keeping the 906/Manifolds/stock converter.
