Mustang & Fords Blew up 21st Century 390 Project
Dang, how embarassing! I feel for the guy. The crank let go after a 7100 rpm dyno test. Personally I question whether it was wise to spin a cast iron crank that high but I'm no expert.
One of the on-line magazines blew up a 428 last year if I remember correctly. Doesn't help the FE motor's reputation much. Anybody else following the story have any other thoughts on it? Was it dumb luck or just dumb? Chuck |
for this 21st century FE, didn't they weaken the block by installing roller cam bearings and weaken the crank by cross-drilling it against the advice of the bearing supplier. Wasn't it assembled in the shops of Jack Roush (Mr Windsor)?
Sounds like they pushed the envelope too many ways; no surprise something gave. |
