Rod Bolt Question
Rod Bolt Question I have a 408 Stroker with Eagle H-Beam Rods and ARP 8740 Bolts. I am thinking that I should have had the L-19s installed as I do want to make 800+ WHP.
My questions are:
Can I simply unscrew the 8740 and put the L-19 in? If so do I need a stretch gauge to do this properly? And can I do this while the rod is in the motor?
Also, since this is an Eagle rod, would I need Eagle specific L-19 bolts? If so, any reccomended dealers?
Thanks!

I am also hearing two theories:
One says that rod bearings bear no significance to Horsepower or Torque loads, and are only RPM dependant. I find this hard to believe because of the more power = more cylinder pressure theory.
The other says, all factors play a part in selecting a rod bolt. RPM, Power, and Torque. I am more inclined to believe this statement.
Once again thanks for the help.

I can shift faster than you.

If the motor is already together, I would not swap bolts. The 8740s are not bad. I prefer ARP 2000s for piece of mind. The L19s are way over kill and do require more clearancing due to the larger diameter head (1/2" vs 7/16").
HP has 0 to do with rod bolt failure. Piston, pin, ring,etc. weight, stroke and RPM (piston speed) play a much more critical role.
