Connecting rods: Press fit or bushed 'floating' rods for street use?
Looking at rotating assemblies. My stocker has what I believe to be powdered metal connecting rods; press fit onto the piston pins (machine shop performed in 1999). Are the bushed rods employing inserts between the pin and rod journal? Is this just something to weaken the small end of the rod?
The SCAT kit I am evaluating has 'SCAT 5.7" 4340 forged i-beam connecting rods... bushed rods for a "floating assembly"...
I tend to favor what I know... press fit. What is appropriate on the street? Time to step up to better (bushed) rods/pins?
The Speed Pro pistons in the kit work with press fit or bushed rods.

I have used both floating and pressed fit pins on my street engines. On a mild build I would lean towards the pressed pins. If the motor is fairly radical and will incur extended high rpm I wouldn't hesitate to use the floating pins. Either will work. Just my .02. Flame on brothers.

Thanks. I'll inquire to see if the kit can be set up with press fit. I don't expect this engine to make over 350hp and won't see high rpms.
I will also check with local machine shop to see if they have recommendations. Perhaps I can reuse my rods with new ARP bolts.
