10.5:1 273 pistons with 360 heads compression ??

The Rebuilder's Choice Domed Pistons from Kanter are taller than the Egges so we'll assume those. I cc'ed those pistons and the dome volume is 11.5cc's. The compression height I measured was 1.769" Assuming your deck height is right on spec at 9.6" and assuming all the numbers you gave above, the static CR calculates to 8.75, which is not as bad as I expected. The smaller thinner head gaskets are helping you quite a bit.

Hi mate,

I realise this thread is old but I’ve been trying to research the 273 Commando pistons, especially the RC pistons you mention here. I recently bought a set of .030 Rebuilders Choice 4bbl Commando pistons and am needing the dome volume. I’ve been reading anywhere from 15cc’s to what you said of 11.5cc, I’ve also heard as high as 16cc. Please see photos attached of my piston/s. Are these definitely the pistons you have cc’d mate? You can private message me if you like man. Thanks in advance.
