Agreed!

You know that to reach a 408 is nothing more than a crank and piston change and if your plans down the road is to throw boost into the mix you might want to stay with the 3.622 crank


↑↑↑↑This Man↑↑↑↑ does not recommend installing a 4 inch crank into the LS blocks. The only GM production block that was designed for the 4.000 inch crank was an LS7 which is why LSX is the choice for stroked combinations.

 

Many of us have run 4 inch stroke cranks without an issue for many many miles, including boosted applications. You don't need an LSX block unless you're looking for 4 digit power and at that point go with a real aftermarket block.

 

And I say to start with a real foundation to build on.

 

High revs with a stroker are more of an issue than high power

 

Spending a bunch of money for humble goals like "500+whp daily drivable ish with ac etc" is a waste of money.

 

We have a wide range of stroker cams available. And, they are available through Thompson Motorsports:

The camshaft that Thompson suggested will work excellent in your stroker. However, if you want a camshaft with a little more RPM potential and a little more power, check out our Hot Street Stroker Cathedral Port camshaft. It is specifically designed for your combination.

yes lets pay $500 for a tsp cam .. that tsp specd .. hah

 

Are you saying Pat G dont spec his cams ?

 

Oh really?

This was what I got back from Patrick regarding my LS370 build.

On the attached sheet, please find your custom 238/246 .626"/.626" 111LSA +3 camshaft recommendation. This cam profile features PGN368 custom lobes ground under license by Cam Motion on both intake and exhaust. These .368” lift lobes will give high valve lift while offering improved high rpm valvetrain stability, lower valvetrain noise, and longer valve spring life compared to competitor’s cams lobes of the same duration. These lobes will typically rev significantly higher than Comp XE-R, LSL, LSR, LSK, and XFI hydraulic roller lobes. The cam core utilizes 8620 grade chrome moly steel, which allows the cam to wear longer than the mild 5150 steel used by so many competitors. You can order this cam directly from Carolyn Taylor at Cam Motion. Carolyn will give you the $445 Guerra Group custom camshaft price. Her contact info is on the attached sheet. Any questions, please write back.

Mild steel cams last 200K, granted they aren't as high lift, maybe that makes a difference. I'd be more worried about spring life vs cam life.

I'm sure Pat G does a good job speccing cams but unless you are a hardcore racer I doubt there is a huge difference vs a good off the shelf grind.

 

I have to agree with this. The hardcore racer is looking for that last 1-2% at will show on an E.T. that a street user will never feel or realize. For him, it is about guaranteed there is a shelf grind that will get the job done, like wannafbody says.

 

I was actually looking at the torquye stroker cam wondering how well that will work

 

yup LS3 heads love cubes

 

$445? Hopefully that is shipped plus his custom fee? I have had zero issues going straight to CM for custom specs and paid less and have made more power than others on a similar dyno.

408, horsepower sells but torque wins races.

 

Bottom line is that if your only going to be an NA street machine then go for the biggest cube engine you can build.

On an LSX standard deck block once you've past a 4 inch stroke then engine longevity becomes a factor. Especially for those who don't baby there **** and are beating on it all the time and using power adders. I decided to stay with a 4.00 inch crank as I do have future plans for the engine and I could go bigger on the bore to gain some more cubes but if twins are in the future I still have plenty of meat in the cylinder walls at 4.125 bore and will make way more power with the turbos over the cubes.

 

Agree and approve. Build a combo you can afford with no regrets!

 

If you are spending money, build what you want once even if it means waiting a bit longer.
