    Aluminum rods for sure on blown injected engines. The rod is able to absorbe the extreme shock and rattle the piston is battling with and keeps the motor alive. A steel rod like that will usually rip off at the crank side.
    Several people make good aluminum rods, BME, Brooks, grp... and so one, but dont buy the cheap ones from jegs. lol. Talk to some of these guys and tell them what hp you are trying to achieve and get back to us!

    Hope this helps!

    found set of GRP'S with 15-20 1/8th mile runs on them[said never used nos with them]..priced at $450.00 would these be good to buy?

    :roll: Did you stand there and count the number of runs & see that no nos was used ? You're paying a little less than 1/2 price, over a set of new rods, with no nos and zero runs !

    If you lose 1 rod, how much will it cost to replace everything ?

    Simple math and the theory of probability... good luck !

    rods

    personally i wouldnt buy any used aluminum rods from anybody unless you saw every pass they made, i had a guy who bought a motor that was just gone thrue and ready to run and built by a professional race shop so the guy told my customer and i told him to open it up and look at it and we found cracks on every journal, aluminum rods were 12 thousands out of round, harland sharp rockers on 300 lb closed pressure springs, 3 bad pistons, so be careful not to try and save on parts and later pick them up at the track ,, also look at the parts page on Racing Junk and you will see alot of parts stating dyno time only, i always get a good kick out of that saying, good luck

    Blower is is almost a requirment for alum. rods!!, Steel you most likly will have problems. And used alum rods, I wouldnt go there. If ya do that you might as well get the 500$ specials from jegs then at least those would be new. LOL.... GRP, R&R, there are a few others that are good. You get what you pay for. My boss Jeff has about 12 sets of used R&R alum rods laying there 1 season on them but thats a good spot for them in a box.
