you'd be better off going with a shorter stroke big bore motor, but if you are set on building a 383 put a 6.125 rod on that 3.75" stroke crank to have a rod/stroke ratio of 1.63.....most high end engine builders like to see a rod/stroke ratio of 1.8 or 1.9. The 6.125 rod is the longest you can reliably fit on a std. 9" deck and still have a 1" comp height piston.

can you get a 6.125 rod cheap like around 300.00 and what piston do have to run

SCAT does make a 6.125 H-beam 4340 rod for $359 from www.flatlanderracing.com As far as piston I believe SRP makes a off the shelf piston that will work for this combo....probably around $400 for the pistons.
Call 316-755-1144 and ask for Dave. He can beat flatlanders prices and have it directly drop shipped to you. Just tell him what you are wanting to build and he can help you out.
