LS7 Heads/Cam Record!!!

[@ryanbrown918]

You guys are really making it hard not to buy the parts to go from a "Stage 3" to "Stage 4". Good God. Well done guys 👍

[@josephfamularo469]

Fuck the haters, to make 600+ horse power NA out of a 427 cubic inch stock block is insane. I come from the early 90s of street rods, where if you made one horse power per cubic inch you were killing it on the street. Keep up the good work!!

[@dennisrobinson8008]

Back in 2000 to 2002 or so someone would be happy to have 500rwhp out of 400 to 427 cubic inches. Many didn't even make that much.

[@mr.wildcat405]

I was thinking the same thing. Was scrolling expecting a hater trying to steal their glory.

[@dennisrobinson8008]

With the mighty LS the bar has raised for at least 1.5 hp per ci. Even on a street car. It indicates an effective build.

[@ivonevistic3776]

Well where I live we don't have such big engined cars but many ppl do 1hp per cubic Centimeter!

[@HioSSilver1999]

Great job!! highest h/c ls7 I've seen was a little over 700whp. A very well documented build on ls1tech. Of course dynos will vary.

[@dennisrobinson8008]

these cars are completely awesome.

That's nuts! And those C6Z's are like 3,100lbs.. LS7 is a beast

[@TheRealDarthVadar]

This thing is a monster imagine the right tire wheel setup and a shit ton of weight reduction as much as possible and still remain somewhat factory looking 😮 me thinks it would be a absolute animal

Wow i think this is the biggest number for horsepower in c6z stage 4 on channel , well done 💪😍

Okay! Danm, that was insane HP & T , my hats off to all you guys there! Making tremendous amounts of HP everyday! 👍✌️

Fran the homemade looking vent was GM solution to the power steering pump overheating I did it on my c7z and never had an overheating pump on track even in 95 degrees.

[@probation2propagation420]

People don’t realize how fast that car is because of how light it is. 670WHP IS INSANE at that weight

[@omegasquad868]

hey Fran and company i know you guys have your B3 cam as standard but have you ever thought about trying the Cam Motion LLSR suppose to be easier on the valvetrain and make more power and yea i know its pricier overall especially having to buy custom rockers but your customers im sure have that money lol dont beat me up too bad its just a question i enjoy watching your results good work guys!!! 😎

[@beronib888]

[@jamescundiff3264]

Not sure what changed in your video production but it's a lot more fun to watch your videos now. Especially with the wifey behind the camera. I haven't really watched the channel in about a year. Good stuff though.

Great content as always I’m a C6 guy so anytime you do stage 4 kits plus get great results I’m super pleased keep up the great work guy’s

[@julionavascues6642]

I see you have a GTO in the background. Are you back to working on 2005 to 2006 GTO's?

[@chrisiztheman1618]

Hey Fran, do you think the ARH 2x2x1/8” race header with the 3.5” collector would add any power on a stage 4 car compared to the standard 2x3” system you normally use? Also maybe a 3” Corsa or Borla axle back vs the stock 2.5” would add some hp? Might be worth testing

[@RaceProvenMotorsports]

I can’t see the header picking up anything on an NA setup. We will never know till we try but I’m certainly not spending 3k to test it haha.

[@813Goat]

A high compression ls7 switched to the race headers and picked up almost 30whp.

[@CamaroThings]

17:14 I am one of those people asking this question only because Fran *NEVER* used to post it as crank hp... you know why?... S6 E22 30:54 or S5 E32 21:03

[@rookerb1]

How much power does the Honda Pilot in the background make?

[@Omar-bh8yf]

I have a silver zo6 from jersey last year that was there. Base lined 489 and made 640 STAGE 3. Had the record for a while for stage 3. Car fucking rips. If I made 640 stage 3, stage 4 could possibly add 30 hp.

[@Omar-bh8yf]

I wonder what the price difference in price would be on a lt5 to swap to a Holley vs unlocked stock ecu

[@trey8543]

An unlocked ECM is $2000 from HPtuners, the Holley terminator kit runs $2600 plus whatever install costs. Save the $1000+ and put it towards port work or headers..

[@vbmods8945]

question rpm team, on a ls motor fuel pressure drops at high rpm's 4100RPM would a hot wire kit help it? & when i install it does the hotwire kit need a tune? i know u guys dont work on 02 camaro's anymore but if u can help a brotha out i would appreciate it 🤞🏽

[@sincealways2212]

The SAE number is even Cooler 666

[@dennisrobinson8008]

Impressive for just under 7000 rpm. Why not a combination with a 8500 power peak?

[@RaceProvenMotorsports]

Bc this is our standard Hc package. If someone wants to spend 45k to reg to 8500 we can make more power with a different combo.

[@dennisrobinson8008]

@@RaceProvenMotorsports Good one. So it crested 670rwhp with one of your known combos... That's completely bananas for a street N/A machine. The TQ numbers are bananas too.

85 o/o ethanol is 85 o/o, don’t believe the other 15 o/o makes a big difference. The power is in the ethanol.

Is there a way to make 700whp N/A with a stock bottom end?

[@RaceProvenMotorsports]

Probably not no.

[@813Goat]

Frankenstein F710 heads made 709whp on 93. Done by KK Performance.

[@RaceProvenMotorsports]

Not on a dyno jet I don’t beleive

[@ryanbrown918]

Thats actually a good question. What is the next hurdle to crest 700whp on an LS7 Fran? Is the bottom end a restriction due to "rev-ability"? I gotta imagine between a Holley Hi-Ram and Frankenstein Heads, it would have plenty of air flow. Could always run a second pump with bigger Injectors if fuel is a restriction. Last thing I can think of is too low of compression on stock pistons... Hoping you have the answer Fran!
