I'm starting the process of building a new 383 for the roadster. Since it doesn't look like anyone makes forged dome pistons for a 4.28 or 4.31 bore with a 1.32 compression height it looks like I may need to order a set of custom pistons. I basically need the Ross 99499 in a 4.28 bore.

What's everyone's favorite source and what kind of price can I expect?




I have a set of the pistons you are looking for, what stroke are you planning on building?

The piston is a custom Diamond with an effective 9.9cc dome , 4.280 bore, 1.32 CH, CNC lightened , coated skirts and ceramic coated top , they cost me $1100 when I bought them back in 06.
