383 into a 68 Valiant

Wow, another guy from Omaha and another guy with a 67-69 Valiant! What are the odds! Glad to have you here Glue Man!
A buddy of mine started a Facebook page for Omaha area Mopar nuts...check it out.

It's certainly easier to put a stroker small block in one of these.. if you are comitted to a BB using a 73-76 K frame makes the job a bit easier.. there is a post here or on Bigblock dart.com that shows you how to move the brackets back to make it near a bolt in.. but you still have the weight bias and header problems. With a later K frame it also makes it easier to put big bolt pattern brakes and better sway bars on if you are so inclined. And you get rid of the biscuit style mounts too. Not a big deal in any case.
I know a number of Mopar guys here in town and it never hurts to know another. Take care looking forward to seeing your project!
