Before I button it up which rod bolts

Post  738drvr on January 10th 2013, 11:57 pm

Came with 8740's. Assembly has been balanced.

Scat 4.500 crank
Eagle 6.800 H beam

552 should turn 65-6700 rpm. 700+ N/A plus a 100-150 shot.

Pistons weigh 566 g.

8740's or 2000's?

Don't change rod bolts now, unless you want to resize the big ends. Use the bolts that came in those rods, (the 8740s) and they will be fine at the power level and that rpm.

Thanks Charlie. I read on this site that Eagle states you can run the 2000's without re-sizing. The L-19's require re-sizing. Just want to make sure I'm safe.

If you decide to go with the 2000 bolts you will need to have the rod big end checked. Any time the clamping force is changed it is possible that the bearing housing will distort. This is why the rod big ends are always honed with the bolts installed with the correct lube and are torqued or stretched to spec before honing.
