That's the one. 9.72 SCR brings me to around 8 DCR. I understand that's too much for pump gas. My plan was to build a punchy street engine. Auto with 3.23's. I have a voo doo 268 as well, but the intake valve closing on that one seems less than the xe262 which again raises my DCR.
I'm running a low lift (.421/.443), low overlap, low duration (204/214 @ .050) Erson RV cam with 9.8:1 CR, just use a 30% ethanol mix and you should he just fine
