I'm thinking that with a Dana, the weight goes up a tad, then it makes up with the lighter coil over suspension up front.
If you have an all steel body with the exception of bumpers and or hood and factoring in that an all aluminum big block motor is about as light as an all iron small block, aluminum passion tranny and a seemingly lightweight bell housing, you'll end up in the 2950 pound range more or less.
Anyway, love the build and I LOVE STICK cars all together.
