howdy all,, i posted this question that was answered in another thread to id a trw piston # , but it was an older thread.
i'm 'redoing' this engine since i filled with water sitting out back for two years,,(the stupid blue tarp leaked !
so, i hove no idea what cam was installed , it measures .455 or .466 , i want to go larger, the pistons have .300 or so valve reliefs
a slight chamfer around the top , signifying a little 'dome' , not the flattop. so knowing about the compression ratio will help in my cam decision,,
inside on one side is TRW the other has 463-99
looked and looked, can't find any info ? was even thinking getting old 1985 TRW catalog off ebay??
if anyone has info on these pistons, greatly appreciated
