Compression question...
I seem to remember seeing a chart years ago that gave ball park numbers for compression test numbers to compression ratio. I know it's not that accurate because of cam timing but I'm curious as to what ratio my 400 sbc is. I'm running "292" iron heads that have been shaved some, but I don't know how much. My cam is around 250 deg duration, .530 lift and a 110 lobe centerline. The pressure on the cylinder cold cranked is around 235 psi.
