Hi folks, I have 3 one-piece solid piston ring compressors bought from Kenne-Bell back in the day. One is for a 040" over (?) 350 c.i.d. and 231" (3.84" diameter) and one is for a stock-bore 455" (4.312" diameter) and the other is for a .030" over 455" (4.342" diameter). Much more solid than the thin, sometimes plastic ones sold today. $30.00 each plus shipping (my code is 29803). Thanks! Best, Ranger Aiken, SC
