fifth row down 1/3 of the way overWhere the hell is the popcorn imoji lol
That's definetly not me. I built my LS myself with research, talking to TSP and other top engine builders, then had a guy on LS1TECH who is VERY well respected port/polish/mill/assemble/flow a set 9f stock 5.3 heads for me. It took me almost 2 yrs of research and talking to people to get my combo like I wanted. In the end it laid down over 400rwhp on an initial dyno on pump gas and stock tune with 80k miles on the combo. I daily drove it and spun it to 6500 at least 3x a day for years.
I'm not here to argue and I'm not going to post 8n here again cause this is getting off topic and I do not wish to turn his thread into a dick measuring contest. But you ain't got no Virgin here.....
first... i was giving what id like to do with the engine..... the question was toward the fi systems themselves... and the limitations of the oe system and ease of tuning it with dynamic...
next i thought this was a car site not biebers fan page... whats with all the wadded up panties...
so next if i were going for out and out performance id would go ls no question.. its a much better performance base and i know plenty of people that can easily tune those...
next i like gen 1 engines and plan on keeping the short block new cam and heads
and so far ive only seen one person come close to giving an answer to this
What was the vehicle weight and trap speed? I know some very exaggerated dynos in this world. I have seen H/C 6L swapped 6 spd LS1 F-cars barely touch 400 rwhp on a good tune. If you were running a 60E and 8.5 puke driveline those are about 18% loss. 7% on a 450 hp engine is 36 hp better at the tires through that weak ass ticking time bomb of a driveline. I also know for a damn fact you are not touching anywhere close to 6,500 rpm on any stock GM truck tune!
You guys down-talking the LS truck engines have really got me confused. I like old stuff as much as the next guy but the OP of this thread could easily meet his goals with a junkyard 4.8L LS plus a cam and springs if he was willing to run E85. This chart is from the Sloppy Mechanics Infiniti G48 project before Matt put any nitrous or the blower on it. And I'm pretty sure it had valve issues in one of the heads when he got these results...
EDIT - Wouldn't let me post the image directly, first chart at the top of this page. 356HP/308TQ at the wheels naturally aspirated.

I have no idea what the actual dyno numbers for my dad's bone stock '06 3500 with the LQ4 are but it makes the Vortec 350 in my K1500 Suburban seem like a kids toy, even in a big heavy one ton.
That isn't a fair comparison.
First it wasn't in a truck, which really doesn't matter at all, except overall weight. Second, if you know people barely cracking 400 with a tune they DO NOT know wtf they are doing, period.
Only pass i ever made after the combo went in was on street tires, spun while peddling thru 3rd and still trapped 116mph on stock tune and 87 pump gas. This was a T56 car with a **** stock 7.5" 10 bolt and 3.42 gears.
People tried to tell me I was gonna kill the motor on stock tune as modified as it was and running 87 but it ran perfect for 80k and the motor had 100k on it when the heads came off. When I sold it the guy took it to get tuned, said the initial pull was right at 400rwhp and over 420rwhp after the tune was finished, and that's with 80k of my beating on it before he got it.
This was the vehicle in question
