Why not make a 385? All a "383" is is a .030" 350 block with a 3.75" stroke. All you have to do is put the 3.75" stroke crank in your .040" block. That will yield a displacement of 385ci. Summit has rotating assemblies that come balanced and include rings, bearings, rods, pistons, and crank. That is the best way to do it if you are just starting out. Consider this and let us know. Also let us know about what block you have. Like if its a 2pc or 1 pc rear main seal. Also the casting number will be helpful. It is located on the driver side bellhousing.
