There's a lot of carryover from the LT4 to the LT5 (obviously); for example: the heads, valves, and pistons (I'm pretty sure I read this in another article), are the same.
Has anyone found any articles about GM's LT4 torture testing? I think it was HotRod that had a nice article detailing what Ford did with the Coyote engines -- in a nutshell: the torture testing Ford put the Coyote engine through was brutal. |

With the GT 350 Voodoo did they do the same? Very high numbers of failures and even worse record of oil consumption to the point where Ford changed owners manual to state 1 QT in 500 miles is normal. So 10 quarts added between 5000 mile oil changes is normal, 10 QTS! :-) They haven't redesigned the motor after finding these issues right? In recent memory, or ever, can't think of a motor with issues like this and no remedy--like 991 GT3 they should have replaced motors, or at least pistons/rings and bearings at dealer. And ppl still paying over MSRP for GT 350 5 years later. Oil consumption like that would make ownership a bummer.
