D00E Rods are they safe?
by the numbers these are early rods 1970 castings but what im wondering is how much diffrence is there between these and D6VE/D7VE rods and what revs/power are the D00E actually safe for?

I use them in my street stock engine. It is a 466 thats got stock block/crank, light pistons, and new FMS stock rods. These are exactly the same rod as the old SCJ and also the original FMS 514ci crate engine. Ford has replaced them with an H-Beam on the crate engine after to many failures. I do not use my engine many hours, but in the last couple years I have put about 60-70 pulls on it with an average track RPM of 6200-6800, and about 5 of them spun upto 7200-7500. I feel 6500 is not to much ask....and I cringe at the thought of 7000 with these rods. (But I would NEVER let off the throttle!) I also do use ARP's best studs, and just to note-I never cleaned/dremeled the casting lines or did anything to stress relieve these rods. Forgot, you asked HP range. I can tell you that I make 400 rear wheel HP, so most likely about 550 flywheel HP. Like I said this is a stock class engine, so it is not a big power maker, its just a mild performance rebiuld.

I think your gambling anytime you spin past 6500-6700 RPM with a CJ style rod up-graded with ARP bolts. Also, unless you have SVO heads or other pro-style aftermarket heads you are spinning past your power-peak anyway once you exceed around 6500 RPM.

I wouldn't go over 6,500 with them. It's usually the pin end that fails or they break in the middle. I pulled the wristpin out of onr of mine last year turning 7-7,200. Their isn't much meat in the beam either their thinner than they look. The key to making them last is to use light pistons.

With proper stress relieving, arp bolts, and shot peening, these rods are good to in excess of 7500 rpm. They are almost as strong, and approximately 50 grams lighter than Eagle H- Beams. They hold up to over 650 hp in this application.

Great isn't it? 5 years this year, we change the oil and its another year of 6000+rpm. If she blows, we'll build her bigger and stronger!

so the CJ Rod has only the D00E casting with no additional numbers and letters following it?
ok im going to attach a photo to show my concers, incidently my combo is set up to turn to 6500rpm with electronic limiter so that will be tha max. On the photo u can see both the casting numbers and the arrows pointing to my worries, i have always ran 351 clevelands in my cars till now and find the rods seem to be better built.

No problem man....spin her up !!
Yes i run a 6AL w/ 6800 chip too.......And the "tell tale" doesn't lie either
I'd post some pics, but it seems certain members are "whining".........Have no fear the rods are safe.......

I consider 6500 safe with those rods. I know a guy that had used the SCJ rods and really put a wild thrashing on them....consistant 7500 rpm runs. At 6500 I dont even think about the rods. At 7000 I get a bit nervous, not that I have personally ever seen or personally met anyone that broke one at 7K, but because of the horror stories like you read above.....At 7500 I actually do get a bit jumpy, I turned white the one time I hit the recall button and say 7800 RPM after a pull. Can you say ooops!!! By the way, those same rods are still going strong and this year I am going to go with a rev limiter and set it at 7000 RPM. I know some will say that 7K is too much for my stock engine, but what the heck, its fun to prove guys wronge!

I had ran mine for 6 years at 6,500+ with floating pins with no problems. I put bushings in them last year because some were getting loose. I broke the output shaft in the transfercase and the pin pulled out of one rod all at the same time. The motor didn't over rev because of rev limiter set at 7,250. That one rod caused 14 bent valves, bent cam, broken timing chain dowel, busted cylinder and two broken pistons and one bent rod. If I hadn't put bushings in them this probably wouldn't have happened. Like I said earlier light pistons are the best way to make them last.
