It would depend upon how many passes you would need it to last.  Smile

i've had a couple 460's.. newer ones.. 87-91 motors. that the pistons break apart...

i'm going to set the rev limiter at 4700.....

Don't know about the newer pistons. My 429 has D1 short bock with stock pistons and a mildish grind hyd. cam. The bottom end and pistons worked fine in 1/8 drag racing, with 150 shot of N20 for quite a while at 5,500 rpm. It would most likely still be going, if I had not dropped a valve. At least if the bottom end goes you are out of less money. I was impressed with the stock parts.

6500 is more like it. We run them a lot higher

Know of a 429 run in a 58 Edsel in the late 1960's. Cam, upgraded valvetrain, homemade TR, stock bottom end saw 8,200 rpm more than once... cast pistons tend to break off the skirts after awhile...
