Ever heard of Boostline rods before?

[TheBac]

Was browsing online and came across a "Tomorrow's Tech" article where they mention Duramax rods from a company called Boostline. Anyone here heard of them before? Opinions?

Pretty popular for LS guys

Yeah they use them in some imports too! Seem to be pretty stout.

I don't understand them at that price point. They are likely made off shore and finished somewhere in the US. A few hundred more you can have Carillos. At that price point might as well save $1000 and get some Callies Rods as they're likely comparable quality wise.

The Callies rods are a good deal, but are heavy. I have used them at least twice and had to add heavy metal to the crank. Even the Callies cranks will need weight added. Looks like the Boostline rods are about the same weight as stock rods. So are Molnar rods. I will be using the Molnar rods here sometime soon.

What's the swing of Weight of stock rods? Compared to these?

From the article in the link

"It might be the resonance you get from the different firing sequence that the LMLs have"

This is news to me. I thought they had the same as all the others.

Well that doesn't look heavy. I will look tomorrow and see what I have wrote down.

Quite a few eye rollers in that article

I was wondering when someone would comment on that.

I went back and looked in my engine build thread, LBZ rods averaged 1175 grams.

 

[pl_silverado]

Found this on the other site.

On an average........................

I show the stock LB7 at BE 769g and SE 388g. Total 1157.

LBZ 770g and 392g. Total 1162.

TTS/R&R 771g and 387g. Total 1158.

Crower 766g and 388g. Total 1154.

Carrillo 666g and 412g. Total 1078.

Remember, for balancing purposes, the big end weight of the rod and the rod bearing are used twice in the bobweight calculation to accurately simulate the two as they are bolted up to one rod journal on the crankshaft.

So for every 1 gram of additional weight gained or lost on the big end of the rod, it counts as two grams in your final bobweight.

I went with the Comp Stars as well on my build.

I've used the Callies rods in a few builds and didn't have any balancing issues. I have another set here now for a motor I'm going to be putting together for my old LBZ.

 

[Bdsankey]

I've used a few sets of Callies rods and also had zero balancing issues with them. I've used a few of the Brian Crower rods and had the same result. The Wagler budget rods are quite heavy compared to the above rods as well as SoCal and Carrillo.
