Best heads for 500hp?
I'm currently working with Tony on my current LS2 build. Working with Tony has made engine building fun and exciting again. Yeah, its expensive, but you are going to have a great outcome. Granted my engine is not done yet, so i can't report on how well it works. Tony has helped me out of two lousy situations already which is above and beyond what i expected.
MSD manifold- 1200.00 unported, 15-1600.00 ported
Motion TB- 450.00
Frankenstein heads run- 3500.00 minimum and up to 5k for the F110 247's. Not sure on Mamo, but I assume the cost is in that realm.
Cam and good valvetrain setup- 2k
Kooks 2" and a good exhaust- 3k
10k minimum in 2025 for a 500whp LS1 NA just touching the basics. Not including air induction, fuel system, EWP, pulleys...etc
Basica cookie cutter LS1 stuff for under 5k is going to make an honest 400-450whp SAE on a DJ. This power can be made with ported 243's, LS6 manifold, cheap exhaust, cheap fuel upgrades...etc. 500whp takes a lot more money. Can it be done easily Yes, but again it takes a lot more money. Most are going to go bigger cubes or FI these days.
Spoke to tech guy at Texas speed. He stated since I’m already at 422rwhp there are no head cam package that will get me another 78 hp even if I change to msd intake on a 5.7. Not worth money he saying. Running a base procharger will get me over that mark he stating. Shocked no heads out there can’t get me close to or just over 500rwhp with Westin have so far. Gonna see about a procharger.
@Tony @ Mamo Motorsports .....
My car at 450whp and 500+ wheel was no different drivability wise. Most all idle and drivability characteristics are solely tune related. I could idle around in 1st gear at 1-2k rpm with no issues, as well as cruise the car in 6th at 45mph without bucking.
I have seen baby cam cars surge and buck... If the tuner can't tune, idc what cam is in it.

There are thousands of dyno results in the dyno section. Show us 5 cars running stock Ls6 Heads and a Ls6 cam making your "typical" numbers. With an NA pump gas 346. Should be easy since its typical.
Never said upping the compression is a bad thing. But most will want to be able to pull in any gas station and fill up with 93. If your running 12.5:1 or higher....your probably not filling up with 93.

Why 500 rwhp? Why not have et goals instead? How important is Drivability? Daily or Weekend Warrior? There are more important factors and goal than 500 rwhp in my opinion.

If you have an auto trans your not likely going to see 500 wheel....if its a manual we can get you there.
This was a recent customer result with only a 229 camshaft.....besides making big power the car still drives excellent.
He is running my lightweight RPS clutch which adds about 15 at the wheel but even so you need to look into these results with a fairly basic easy to install package

And getting hold of me is easy.....Email is best if you're typing or just pick up the phone and ring my cell

**** combos aren't typical......well they are but that’s completely on the owner. I mean go copy a **** combo......doesn't make any sense to me but that seems to be your goal.
A friend on here copied closely to what i did on here with my bolt on ls6.....he made 44xwhp. Another a fella on here went 10.0@135 with a bolt on ls6.....it likely made atleast 450whp.
So yes a ls6 making 450whp ish is typical......if you do it right. If you don't then that's on you not the engine.
I can tell you 12:1 seems to run fine on pump gas....12.5 might be ok. More might be ok......don't know until you try.
True but let's be honest, Take 100 H/C LS1 setups and 2 might legit make that much power because most are not going to put that kind of Coin into a LS1 anymore. It would cost more than a mild boost setup.

My numbers aren't even maxxed out.....still on pump gas. So you could easily add 10-15 on to either the bolt on ls6 or my current 5.7 with some e85. With my current 5.7 i was even still turning the ps pump. I did bypass that for the bolt on ls6. Mainly to put it on par with these newer eps engines for dyno purposes. So i guess your 5k comment is wrong because i included my rebuilt bottom end in that......you people are just hung up on **** combos.
If gm still had the gmpp cnc 243s it's cake......you could even use a gm cam to get there.
Okay so what are you using for pump gas Hio E85? How much compression and what are the cam spec's? What all has been done to the factory cylinder heads? How about induction and exhaust system? You say a 9" rearend well what gear are you running? Is this an Iron or aluminum housing? What about the transmission? What do you have going on there? What about weight reduction on the car?
Real questions to help me wrap my mind around that 500plus rwhp 346 laying down low 10 second passes.

Idk why you would have a issue with 500+ whp cars running bottom 10s or high 9s. That's kinda where they should be. Unless it's a gutted race car then they should be faster.
I've mentioned what my compression is. I have 3.89s in the car now and a t56. Almost erry car has weight reduction. If it has a drag pak on it then it has weight reduction. ......my car still has the jack/spare in it. My rw when it went 10.7@130ish with the bolt on ls6 was a little over 3300. Maybe 3350 even.
That may be true. But who cares about high dyno numbers? Theyre for tuning, nothing more, nothing less. A 400whp number on dyno A might make 425+whp on dyno B. Let’s say you're racing someone stoplight to stoplight, and you're dead even until you hit 2nd gear. Then your 10 bolt blows, if the winner comes back to try to help, which I doubt, most of us aren't going to say "Ill bet my car will make more power on the dyno than yours will." To which I'd reply "Not right now it won't!"
if you don't care about a dyno then go to the track.......but that can be wildly different. You have guys in this thread crying on dyno numbers. But what's that really mean when my bolt on ls6 trapped 130+ on pump gas in a street car. Even drove it a hr to the track. Does that mean it has more power than the dyno said??
I asked those questions in search of answers hoping that you would share that was all. Not looking to go searching the forum for your posts in order to hunt it down. Not saying that what you've accomplished in the car is not doable just wanted you to answer those questions but you may have answered some of them but then not the answers I was really looking for.
I've said multiple times pump gas.

all the dyno jets I've been on seem really close.....definitely not 25hp difference.

My comment wasn't aimed at HioSSilver. It's more about people who think inflated dyno numbers mean there car is faster than someone's car that puts down lower numbers. Through the years I've seen people claim a cam only 5.7 puts down 450 hp. Maybe their dyno slip says so or maybe they are just full of it. It's amusing nontheless.
I'm not really aware of a lot of people running over 11:1 compression on a daily driver type of 4th gen. Sure cranking up the compression can make power but is it going to hurt the engine long term in hot and humid conditions?

Procharging the LSX427 is exactly what I'm wanting to do if I end up going back through this engine, that is if I can stick around long enough to see it through. I'm about to achieve something I've never had in my life and that's financial freedom..56 years old and no more mortgage, boat and ATV payments..To be able to earn money and not watch it leave as fast as you make it. I'll be happier than a pig in mud!
I'll tell you one thing for sure. I can't justify spending the kind of money that's being asked for automobiles these days. Something has to give and I'll be one of those that gives up and not give in. I have two sports cars, one for the street and one for drag, I have a 4x4 SUV and two pickup trucks and they're all LS powered so I'm good..
