Me and my brother had a 1970 318 sitting around with 53,000 original miles, we picked up a set of 1991 360 heads (308 castings) from the boneyard and a 340 resto cam from Mopar performance. Bolted it all together with an old cast iron 360 4-bbl intake, 800cfm Thermoquad carb, headers and electonic ignition and put it in a short bed 1979 W-150 4x4 truck. We promptly wasted the transmission doing burnouts with 31-10.50 tires on the back.

Make sure your trans is in good shape prior to the swap.
