Steel Rod blower motor?

How well will a good quality steel rod(crower billet, oliver billet etc) work in a 540 chevy 14-71 30psi 7400 rpm, safe tune up no detonation.
thanks in advance

 

I used Oliver rods in a big block chevy motor I built for a grand prix boat,only had a 10/71 on it but no problem. Just make sure it's balanced.

 

I was told by the experts here and abroad that above 1500 crank HP, expect to be replacing the crank every 15 passes or so with steel rods.

 

steel rods

I ran steel rods in my SBC with no problems....just keep the timing out of it and watch your plugs. If you are just bracket racing and not trying to run TA then you should not have a problem. I am freshening up a BBC right now that had steel rods....dropped a valve but that is not the rods fault, the crank mag'd fine. Peak cylinder pressure BTDC is the problem, if you run a safe tuneup you will have no problems. Have a good day.

 

We are running Oliver steel rods in our 560 BBC and have had no problems sofar (3 years) . Running a 8/71 at 50 over (20lb), changing gear at approximately 7500 and running 7900 at the finish. Burnouts sometimes see over 8000 if I get excited and last year we had a converter issue that saw it pulling almost 9000 every run for several meetings. We are conservative with the tune. Every winter we cracktest and measure the rods and they havent moved at all . We have a budget CAT crack that has now got 3 small cracks in it.
Hope this helps.

I run 496 chevy with Crower steel billet rods and Crower blower crank. I have had to replace 3 rods in 3 years. 2 rods due to way lean melting down head crossing over into other combustion chamber causing pre ignition and bending the rods(fuel pump went out) 1 due to aluminum melting down onto top of rod and can't get the pin out of rod. I leaned a tad too hard on it and it let go at 1000 ft mark. I run 25-30 psi boost with fairly advanced ignition timing with Super Mag 3. 6.76 @199 shift at 7800-8,000 and trap out at 8000. I measure rod bearings after each weekend and had over 1 year on same rod bearings and I could probably get 2 years or so on mains but they usually get changed out at the begining of the year. Crank has never been out of car since put in 3 years ago. I use Crower stuff in both my cars.

 

bbc crank

how about eagle cranks for bbc blown with steel rods for 1000 to 1200 hp 7.50s in an altered. are those cranks any good for that hp range. thx

 

Ran 6.78 at 197 with an eagle 4340 4.50 stroke crank. Prior to going blown it was in a 950 hp injected motor and had 100 + runs. Bearings always looked good. After kicking a rod (not crank related) we magged it and found two small cracks. It is now retired. For $675 I think I got my money's worth.

 

fwiw... i have one in my back up motor: bbc alky, aluminum rods, 14-71, 6.80-90's 200, has three full seasons on it... mags fine never hurt it. guessing somewhere in the 12-1,400HP range. i think with a safe/smart tune-up you're fine

 

what stroke thx
