Roger, if you can find one, and they are out there, have you thought of putting a 312 in it? I built a 312 back in the 60's and it was a hell of a motor (until I slung a rod through the side of the motor). Would crank 8 grand and ran like a top. Cut 060 off the heads, bored it .125 (324CI) and had a Crane cam and dual point distributor in it. It ran like a bat out of hell. Had it in a 57 Ford Customline 4 dr. .. Was so cool to whip up on some bowties ...
