RE: SV: 1962 Plymouth - 361 or 360?

[Paul Lennemann <pjlenn@xxxxxxxxx>]

My '63 factory service manual shows the 318 & the 361 w/ a compression 
ratio of 9.0:1, I've got to think the 360 is more on the order of 8:1. 
Seems like there's a cost savings there by not having to do anything to 
to get the compression ratio up.  I'm just guessing at the 360 ratio 
does anyone know for sure?
