hi ,
i have a 511 hemi .
previous owner wanted max cu without boring it , new block .
10.25 comp .
hyd roller can drive anywhere .
i go to track app 6 times a year .
otherwise drive anywhere
if i would be doing it i would use a 4.15 crank for a little low end boost .
i can tell i have 511 cu in to feed every time i need fuel more motor than i realy need !
a little less cu in would be fine 472 maybe . with 10.25 comp. better milage , plenty of power .
i do not like the hyd roller as it is noisy , i would use a solid flat tappet with a tight lash .016 quieter than the hyd roller !
if you have a good crank and rods sell them and do the 4.15 , more torque at lower rpm and still verry driveable with right cam .
