Eagles are cheaper; think theyll do for 5500 rpms max. I was gonna do Edelbrock heads but Ill probably use some 6X 400 station wagon heads like I have on the GV.

I bought the Molnar Power Adder 6.8 billet rods. But for this application the standard rod is more than enough. Used on 1200HP engines. I bought the Power Adders simply because they can take far more power than I will ever put out and still, are lighter than the Callies rod. 1600$ vs 630$. It cost less for the Molnar rods as the money it would take me to rebuild my Crower billets to take 7500RPM. For more RPM than that just the bolts are 700$ then the rebuild. Bought the Molnars and still have the Crowers for less. |

Brother I've run RPM, Eagle and Scat in Pontiac stuff. I've not run a stroke over 4.25 with those rods. I've not had any problems with any of them. I've run 4.25" stroke engines with these rods to 6500 rpm with no problem. I've run 3.75" stroke engines with the RPM rods to 7300 rpm with no problems. I think all of these rods run higher rpm without issue. The problem is the bolt strength on the cap and not the beam. Upgrade the bolts and you'll be good.

I am not the guy to ask. Tom Molnar will talk to potential customers about rods and cranks.

If you are road racing, canyon carving, all posted will hold up. I would pick the lightest of the group. the eagles with a arp 2000 bolt are good to 1500 h.p. per there web site.
I would think you would want the lightest rotating mass possible so pulling from corners the rpm's come up faster. Just my .02 I don't r/r but have a friend who does. |

Callies Ultra rods are made with 4330 and Olivers are 4340. You cant go wrong with either one.

I went Eagle H-Beam CRS6625P3D in my 455 build winter 2013 and push the car in street applications. No problems but added a rev limiter for the few over revs done accidentally (no engine problems though). I also used Icon IC888.030 Flat Top Forged Piston Set to further lighten things.
