problably 12 degrees and maybe 250 hp and 350 ftlbs........you need an intake, cam and good headers. also a 180 t stat. then you might be around 350hp and 450 ftlbs.

Thanks, out of curiosity what is the max lift and duration you can use on stock pistons without any p/v issues and how much can the stock springs handle? Im asking cause of my 72 429, but my uncle has a 1969 429 he is hopping up, he already has a offy intake, and a holley 750cfm carb, headers for his.
