GOT A 351..stroke it? rod ratio q's

LX XLR8R · 10-22-2001, 10:12 AM

ok i got a 351 out of a 94 bronco..i plan on keeping the motor a roller moter for the time being..here is my proposed combo basically out of a MM&FF dyno pull test

393 coast high stroker kit, afr 185 heads, victor jr intake, speed demon 750 carb, comp cams XE274HR(.555/.565,224/232)..the compressino ratio will be 10.5:1 with the 64cc heads..this combo put out lil more than 500hp at the crank..
now i got questions..i only will bring this motor to about 6500 to prolong the life, what rod ratio do i want for longitivity and being able to rev it that high or higher safley(i know the hydrolic cam will hinder this)..the rod ratio of the 393 motor will be 1.59..they offer a 377 kit witch comes out to 1.655..they alos offer a more expensive 383 kit witch is 1.66..basically what is a # that i should at least get?and how much power can a 351 block handle?
