Dan I have a set of almost new Diamond flat tops , 1.320 CH , 4.280 bore , .990 pin .
Hey John, did you get another set and also not using them? 6 years ago I bought a set from you, they are still working perfectly in my 383 upgraded to 449
You won't regret stroking your 383, I did it and with using a 3.91 stroke crank i made it a 449, runs perfect with a Comp XE284 and made 550hp on the dyno last year
