Guest Posted January 13, 2003 Share Posted January 13, 2003 Is there a way to identify a 1970 10.25 compression ratio 350 from a 9.0 compression ratio 350 WITHOUT the engine oil filler tube sticker, WITHOUT an original carb and with no original documentation? Thanks. Link to comment Share on other sites More sharing options...
rocketraider Posted January 14, 2003 Share Posted January 14, 2003 Short of pulling a head and checking the piston dish, no. If it were originally a 4-barrel engine, odds are it is high compression. 2-barrels came either way. Link to comment Share on other sites More sharing options...
