$700 for one cam!?

A person the other year got a cast cam for that $$$&. Thus my questions on cam core type.

SADI cam core. I am not an expert, but i think the reason for two different intake lobes can be found from head flow numbers i posted before.

Final engine specs. feel free to estimate power/torque

Use a ARP2000 rod bolt. The L19 rod bolt requires careful handling and cannot be exposed to moisture. You can't even touch it with your skin.

Is it really that critical, sound crazy.

Here's a link explaining everything you'd ever want to know about selecting rod bolts:

For what you're doing you could even get away with the 8740 bolt/screw that comes standard with your rods and probably save $100.

From that post on Speed Talk:

ARP 8740 chrome moly “connecting rod” bolt:
Yield strength = 180,000 psi
Tensile strength = 200,000 psi
Cost = $120.00 per set of 16 at Summit Racing Equipment, or about $8.00 each.
---------
ARP 2000 “connecting rod” bolt:
Yield strength = 180,000 psi
Tensile strength = 220,000 psi
ARP 2000 rod bolt material has twice the fatigue life of 8740 chrome moly rod bolt material.
Cost = $200.00 per set of 16 at Summit Racing Equipment, or about $13.00 each.
---------
ARP L19 “connecting rod” bolt:
Yield strength = 200,000 psi
Tensile strength = 260,000 psi
ARP L19 rod bolt material is subject to hydrogen embrittlement, and stress corrosion. It also cannot be exposed to any moisture, including sweat and/or condensation.
Cost = $200.00 per set of 16 at Summit Racing Equipment, or about $13.00 each.

Looking at the L19 description, you can see that exposure to moisture is a problem for the material. Your oil will eventually contain some moisture. It has the capability of becoming a problem. A rod bolt and cap letting lose is never pretty.

ARP 2000 sounds great solution! what would be the arp part number for EAGLE H-beam 7/16" cap screw rods bolts, arp-20000?. what torque specs i should use with arp2000 bolts, rod manufacturer or bolt manufacturer?
