Ford 351 Compression Ratio
Does anyone recognize these pistons? Im trying to figure out my compression ratiio for the new motor Im going to be building. Should I stay with these pistons or go with something else? I may use my old 302 heads.

Re: Ford 351 Compression Ratio
I just finished putting the heads back on my 1970 Holman Moody 351W (1970 Donzi 18 2+3) this weekend. Mine had the same pistons. My HM plate reads 9.6 to 1 compression ratio. What head castings do you have? Mine were D00E-C's.

351W came with '69-'76 .230 dish & 1.739CH
'77-'91 .105 dish & 1.752CH
'93-'97 .180 dish & 1.770CH
Chamber Volume will set final C/R
