I'm building a budget 6 inch rod 383,i was doing very good on my parts selection 'till i got some rods that were supposed to be 6 inch but turned out to only be 5.940...i'm already required to deck the block .050 to get this combo to work,i don't think taking another .060 off the block is feasable so i'm wondering what effects the large quench will have on it.my only other option is to go with a 3.875 stroke crank,but that will kill my budget.

i would be more concerned about the compression you're going to lose...

if it was me, i'd look for another set of rods....6.125", clip .015" off the top of the pistons and leave the block alone. if your pistons are domed, i'd find a set of 6" rods and proceed with your original plan...

where did you get these rods.......from a local guy for a song and dance???? Sounds like a Old's rod.....lots of people use them to build cheap "6 inch" rod motors...

If that's the case......these rods seem to bend easy.....like if you spin the car and let the motor back-up....... Also the big end is a little different is size then a standard chevy rod........ Before you use these rods KNOW EXACTLY WHAT THEY ARE...

They are powdered metal rods(theres another discussion)i was thinking GM only made them in 5.94 but he assured me they were indeed 6 inch..but i got a good deal on them...price wise,you know my pistons have a very generous dome on them,.260 to be exact so maybe the compression loss won't be severe. thanks

anytime you're .060" in the hole, it's gonna hurt. have you checked your PM?
