408 Stroker Build Suggestions

Seems like people are paying $300 for decent LD340 plus shipping.

I’d ask that or trade for RPM plus $175. Must get good pics of unpainted RPM. Flippers here hide stuff under paint.
Wow, who knew. Thanks for the advice, definitely gonna go for that in the next few months. An Air Gap would look really nice under the Holley 750 double pumper I've been looking at.
