Default New Product!! Tomahawk Connecting Rods!!

I am proud to anounce our new line of connecting rods.

Compared with the competitorís similar products, our products are coming with more choices, better strength, excellent quality control, nice looking appearance, and much lighter weight. The machining tolerances of our connecting rods are as follows.

A. Big Bore Tolerance: ≤ +/-0.00017"

B. Pin Bore Tolerance: ≤ +/-0.00017"

C. Verticality, Parallelism and Distortion: ≤ +/-0.00018"

D. Center to Center Distance Tolerance: ≤ +/-0.001"

E. Verticality and Parallelism Tolerance between Two Bolt Holes: ≤ +/-0.0004"

F. Return Tolerance of Big Bore Repeat Assemble: ≤ +/-0.00018"

They are available in H-Beam and a new Ultra Light I-Beam design. We have already tested these rods in over 600 hp aplications. Not 1 problem. And best of all our prices cannot be beat!

Be Cool,
Ace

I am in the process of saving money for a new shortblock for my GTO and was thinking about getting an Enginecraft crankshaft from you and I was going to ask you about their connecting rods. From what I have read on this forum that their cranks are top notch. Is your new line of Tomahawk rods your own brand that you are machining in house or are you having Enginecraft machine your rods.

The BBC versions weigh 776 for I-Beam and 834 for H-Beam. 6.625 Pontiacs are very close.

I have always prefered a I-Beam over and H-Beam. An I-Beam is designed to withstand more SHOCK load than an H-Beam.

Be Cool,

The 5140 is basicaly a "stock" type 5140 steel replacement rod. With ARP bolts and polished side beams. They will sell for $228.95 I believe.

Be Cool,

Great looking rods.
I am with you on the I beams for shock - like with nitrous use but I was under the impression that the H beam still had greater total load capability which would be better for forced induction since it would ramp up. Am I wrong? I will need a set but have not made up my mind which for a forced induction set up.

Yup, Mark. Here is the actual composition.
Component Wt. %

C = 0.37 - 0.43
Cr = 0.7 - 0.9
Fe = 96
Mn = 0.7
Mo = 0.2 - 0.3
Ni = 1.83
P Max = 0.035
S Max = 0.04
Si = 0.23

There are still other factors that can tailor the material to its use. There are actually 142 versions of AISI 4340 based on processing force (forged weight), temperature, quench temp and method (water, oil, etc), nitrided, annealed, etc but all start with a good recipe.

Hey give me a break, I like metal. Especially Pontiac metal.

Blue, they should be about 40-50 grams lighter.
