Long Rods (289) - What a cheap long rod engine? Use 289 rod (5.156" long) in place of the 302 rod (5.090" long). The 289 rod is about a 1/16" longer than the 302 rod. You can use standard 302 pistons and mill off the tops to get the deck height you want. This not only gives you a long rod engine but also a lighter piston that moves the ring pack up for better combustion.-i think this might be worth somthin but what about nitrous is it better to have the rings higher or lower on the piston?

i may be wrong, correct me if i am, but wouldn't that weaken the piston?

i would think to some degree but maybe if you use brand new forged pistons and dident put more tha 100 shot to it i dont think it would be too much of an issue

Some 302s in 69 and 70 used this length rod. So yes it has been done before.
Use the correct pin heightpistons. Grinding the tops off of standard pistons sounds absurd to me.

the gain in most cases may be minimal and IMO a stroker would be more worth while bang

nitrous pistons have the rings lower in the cylinder, that sounds like alot of work for no gains, and will just make the piston weaker.

thanks 91gt thats the anser i was lookin for
