    if your gonna show it and Putt around with a track appearance some of the time..The Steel Rods will be Fine........if you were gonna be racing it and leaning on it.. the Aluminum Rods is the way to go....The Aluminum Rods will absorb a lot of shock that would be passed on to the bearings under race conditions.

    with what you have i would stay with the steel rods imo

    well even if you do more of the racing then crusing..the Steel Rods will still be alright..its not like you are gonna beat the bearings out of it instantly...the aluminum rods just help soften the Hit on the bearings and help with a little longer time period between rebuilds with serious racers having to go back into their engines Monthly/Weekly that run a full race schedule...i do not think the same rules apply to the hobbist that play around every now and then......again this is Just my opinion...if you remember i had a blown alcohol SBC that i ran crower steel Rods..cause i was just playing as yourself.

    not trying to tell you what to do...but we see so many Hot Rod enthuesist trying to follow the Pro's tit for tat...and its just not practical...


    Now if your Going to Run a full race schedule some where each week and push 30lbs of boost @8500 rpm each week thru that engine...you may want to consider Aluminum Rods...

    I agree with Juice on this one, i had steel rods in my 355" blown alcohol sm/blk when it melted down a piston land and cracked the blk., but now have alum rods for the new build to a 383" blown.

    Also i hope you meant 4340 rods with L19's rather than 4130 with L19's?

    Zip.
