Author Topic:   Who makes hyperutectic 377 domed pistons
posted October 11, 2004 04:15 PM
Puttig back together my 377 as a backup engine that used to have KB182 pistons in it and was wondering who makes an inexpensive 377 domed piston for a 5.7 rod? I'm running Sportsman II heads with the 72cc chambers and would like to be in the 12:1 range. The KB 182's are a little too small of a dome for alcohol with those larger chamber heads. If I can find 2 used .020 pistons I may mill the heads to bump the compression, but I haven't had luck wiuth that yet...

Part numbers / manufacturers would be great.

Yeah, but was wondering if anyone had any recomendations - The 5.565 rod piston selection for a 400/377 seems awful limited from what I've seen...
