Piston and con rod dilemma

You can not compair the SCAT I beam to an Eagle I beam, not even close to being the same rod. The Eagle I beam and Stock rod are compairable, and I would use a worked over stock rod before an Eagle I beam.

The SCAT I beam is lighter, stronger with its 4340 forging, and has 7/16 ARP rod bolts, you can even get them with ARP 2000 bolts. They have proven to me that they are the best I beam rod out there for the price.

You want to run 7500rpm for cheap. Ok, but dont expect it to last forever. The cheap way is SCAT I beams, KB 243 pistons. You will see an increase in compression going to the KB pistons over the Speed Pros you have now.
