Im sure the LY rods will work fine on a mild build like this one! They are already resized and balanced with the rest of the rotating assembly. Fairly low compression and not to many RPM's and im sure they will live just fine!
Maybe it's just me but it doesn't seem that mild. To me mild would be stock heads with a cam, intake, carb and headers. This sounds like a disaster waiting to happen! Lol

11-1 comp. 3800 converter and 3.91 gears and .590 flat tappet cam is about as mild as it gets. stock heads cam and intake sounds weak. Might as well build a 383 if thats the case!
I guess only time will tell.

The rod issue has been raised by a number of people, yet you continue to ignore the legit concern. I don't think you really want other's opinions unless they already fall in line w/ your own.

My last mild 440 build had a rod failure. Im certainly not saying they are good rods. I dont have em in mine. My bent rod experience was not good. Im certainly not blaiming the rods on my issues though. Poor machine work none balanced and unfinished cylinders three years of runs and Nitrous was the culpret in my deal. I would certainly agree the rods are the weak link in this build.

Stick with the 440. It may not make the same hp but it'll spin the tires real good.

Surely he will have to turn the screw a bit to get the victor's to work. RPM's would have been a better choice for a 440 with ly rods. If the car is reasonably light, 500 hp would drop into the tens, which could be achieved without having to rev the nuts off it. Mick

If you use stock rods even reconditioned with new bolts they will always be a concern. Better off spending a few hundred now and get a decent set of rods, have the rotating assembly balanced. It will be the best money you can spend at this point.

Going a step past just throwing yet another opinion out there............ Wouldn't the determining factors of using the LY's be the mass of the piston, rpm's applied and the dutycycle/history of the rods themselves??? A .590 cam and Victor heads do seem to be a bit much with forged KB pistons. Lotsa bobweight slingin' around. I would think either less cam, read rpm's, or better rods & pistons would be the way to go. Or leave it dialed on "Kahboom". I'm frugal, but not that cheap.

lots of choice rods - well i'm split.a lighter piston will help,so will less rpm those heads/cam will more likely want more rpm so but then the vert is really too small as well i have rebuilt rods,arp bolts etc, in my 440 but i shift at 6000 trap 63/6400rpm.i have a SRP piston .i won't aim for over 6500 even when i recam it. heck as others have said put my motor in a Abody run 10's. put a smaller cam in it but who am i to say i use a purple 509 cam Tex
