Let's see what happens with headers and a cam.

Is that to the wheels or at the flywheel?

Yes, this has stock DOD lifters
No, the cam advance was not stock. We have done quite a bit of testing with various cam phasing.

Have you guys examined rod bolts in your testing? I've heard through a source familiar with the coming LT-4 GM hipo motor that they're having issues with bolt stretch in extreme durability testing.

Not to mention that the rods themselves have less material on the big end than do stock LS3 rods...

That's why I ASKED the QUESTION to LPE. I assume they have a good reason.
I'll let them answer themselves because you're no LPE either.
I like and respect LPE. I loved their twin turbo builds.
On the other hand, for superchargers, I recall they were selling pathetic non-TVS magnachargers instead of the superior centrifugals for a decade and their turbo builds were out of most people's budgets.
Regardless, I look forward to their answer to my question and future LPE builds with a better blower like a TVS2300 or a centrifugal.

LPE, always loved your twin turbo builds but I've got a question.....I noticed you used the smaller TVS1900 instead of the TVS2300. It seems to me like the larger 2300 would allow the owner to have more options for future growth, and is IMO a better unit. What was the reasoning for going with the TVS1900 instead? Thanks guys.
Same question, you get your point across, and you don't look like your trying to be a jerk.
I actually wonder the same thing! MY GUESS is that they feel this 620hp level is about all they expect to get out of stock untouched heads, so this would be a good combination for people who ONLY want a bolt on solution and do not want to open up the motor. I assume the 1900 is cheaper, so if a guy does NOT want to open up his motor, why charge him for a more expensive unit that would not see any gain? AGAIN, I'M ONLY GUESSING THAT IT COULD BE SOMETHING ALONG THESE LINES. I am NOT saying that the heads will only support 620 without porting, etc. It was just a WAG (Wild *** Guess).

That looks amazing. Isn't the LSA making 556hp with 9lb boost on the same TVS?
Edit: nevermind, I forgot the LSA has lower compression.
