307 pistons in 250?
« on: February 15, 2016, 02:43:48 AM »
I'm planning on running a 1972 250 six in my 1968 rs. I've read on other sites that smallblock 307 pistons will interchange and increase compression ratio 1 point. My question. Has anyone on CRG tried this modification and if so was it worth the effort?
