Happy national 318 day!

Stock 318 that looked pretty nice inside. It got a time set, cam bearings, 1971 340 camshaft, valve springs, and a 1969 340 intake. This is one of our inexpensive small block builds. A long block 318 like this runs right around $2000 without a carburetor, and we usually have one in stock. This set up as a 360 would be another $650.
