SBO 350 compression??
What's the absolute lowest compression ratio the Olds 350 had from the factory in '69? The only ratios I can find from that year are 9.0:1 and 10.25:1. Was there anything in between for the 350 that year? Or lower?

If I'm reading the chart right, the Chassis Service Manual lists 3 compression ratios for the 350.
9.00 with a 2 bbl. designated as QI with a manual tranny, QA, QB or QJ with auto 10.25 with a 4 bbl. designated as QV with a manual, QN or QP with auto 10.50 with a 4 bbl. designated as QX with a manual, no auto offered at the bottom of the page it also says V-8 export options include a 8.3 compression ratio available in 2 or 4 bbl. |
