You could make a 427 cid iron-block engine with a 4.060" bore and 4.125" stroke. Considering the bore, I would recommend it only for a naturally-aspirated setup since cylinder walls will get pretty thin. For that stroke, I could get you a Lunati crankshaft with a custom Diamond Racing piston. For connecting rod choice, we have a big selection consisting of Scat I-beam, Scat H-beam, Lunati Pro Mod, Lunati Pro Billet, Manley billet, Crower, Callies, etc. Let me know what power level you're looking for, and I can suggest a set for you. Also let me know if you're wanting the bare rotating assembly or if you need bearings with it. You can either post up or e-mail me at firstname.lastname@example.org
with the information, and I will be glad to get a price for you.
