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 .
