Compression Ratios


Post by Hauula Pan » Sun Aug 28, 2011 12:50 am

Can someone tell me what the stock compression ratio was on a 1952 FL? My Panhead manual says 7:1 but I read elsewhere it was 8:1 and the supposedly low compression pistons I got a while back are 7.5:1 which would not be low compression if stock is 7:1 so I'm hoping someone can set me straight. Thanks.
