[@sepg5084]

that's what car modding is. how fast do you wanna go vs. how much do you wanna spend. better flowong heada that allow lower boost for the same HP might result in lower IATs which means you worry less about knock, which could mean the difference between using pump gas vs e85 or having better ignition timings. also gives the motor some room to grow for bigger turbos in the future.

[@jaydunbar7538]

Cash represents time spent or risk in the past, if you spend last year's time to buy the heads or time porting it now yourself it makes no difference as both are time spent past or present. Or time spent in the future for those who put such things on a credit card.

[@KCadbyRacing]

Over a 2 year period of time I helped a friend tune his 1080cc (Kaw. ZRX1100) from 120Hp NA up to 500Hp with Turbo. One of the "several" build combinations/upgrades was head work. Long story short, we jumped from 220Hp to 260Hp with the head work (same cams, cam timing and boost) 👍 Mods were over size valves (with proper un-shrouding in combustion chamber), porting (which included epoxy for calculated critical choke area in intake ports). He did raise the compression from 8:1 to 8.4 so not all of the 40Hp gained was from the head work but most of it was...

The roads are too narrow and twisty. Needs to be progressive and responsive. Horses for courses. Some people want a traffic light hero. And that's cool to. But I don't like speeding tickets 😉

[@ThePaulv12]

Heck Ian, even a lazy 500hp from ~ 500cubes in a sub 3500lb car is enough to frighten you with under 3.5:1 gears. The gobs wheelspin from the tall gearing makes the rear end feel like it's on ice. Very disconcerting when you hoof it in a built up area, it steps out and you snap the throttle off, it bites and cavorts off in a direction you'd rather it didn't. Parked cars, poles, pedestrians, gutters etc take on a surreal aspect lol.

I agree, it depends on the budget and power goal. It's not definitely always this or that. It's simply not always necessary for a head and cam package. If you have the cash though. It's always the smart thing to do. For all the obvious reasons you listed. More power at lower boost, more power all around, etc. The right combination regardless which why you go is key. If you want to maximize said combination. That's the biggest mistake most people make. To many try and force a square block in a round hole. Doesn't matter how hard you try.

It depends on if you want a car you can drive daily or a drag car. The thing you have to look at is the amount of heat that you'll generate as you increase horsepower. You can't change the laws of physics. A motor that makes 1000 horsepower is like having a furnace at your feet at WOT. If I were to build a boosted LS, I would add a cam, make sure I had enough ring end gap, and call it a day. The car would have plenty of power when I wanted it and I could go cruising with it. I'd like to drive my car more than 1/4 mile at a time.

I'm a street guy that likes to have a good reliable car or truck. I like to unleash the power of the stock engine with a cam and intake, carb combo. the reason is I'm not a professional racer and I can't justify going all out race gear to cruise the street where I'll never use the maximum amount of of power a race engine can make. I don't need race heads that flow a ton at.700 or. 800 inch of lift to only have a. 500 to .600 lift cam when factory heads flow almost as as good in that range. just like it's useless to put in a big solid roller cam in an engine that won't be revved above 6000 rpm. I learned along time ago to research first ask lots of questions and match the carb to the intake to the heads and cam to displacement and you'll make good usable power for the least amount of money. case in point. my brother has nova it had a 283. he drove it all the time had lots of fun. replaced the 283 with a mild 350 still drove it all the time had more power and more fun. he replaced the 350 with a badly miss matched 400 with 11.1 compression. it's fast and has to run race gas but now it mostly sits in the garage and isn't having fun anymore. he got disgusted with it because now he can't drive it and cruise like he used to. I've tried giving him some ideas to fix it but he isn't too hip to my advice. he was to young to remember my mustang. I blew up 3 transmission and sold the motor

[@mannyr.2756]

I think the best way to approach this is to just get yourself a 4.8 or 5.3 leave a stock boost it get a feel for it and enjoy it and then get yourself a second engine after all there cheap, while your enjoying your first engine and learning you can take your time and build a second engine the way you want.

the one thing you always overlook is hp with octane limits. like say you have a 5.3 with a decent turbo and want to make a streetable setup at say 800 hp but are limited to 91 octane. lower boost equals lower iat which reduces the risk of detonation. aka a reliable street friendly motor. but I really do appreciate and enjoy your content.

I myself am building an LQ4 6.0, which started life as a really high mileage longblock. Completely tore it down, going to bring it to a machine shop and use the stock crank, stock gen 4 rods, and do some forged pistons. Already bought ARP head studs and main studs(nearly $500), going to use ARP 2000 rod bolts. Already bought Harland Sharp 1.7 roller rockers and the FAST LSXRT intake manifold. Going to use a "small cam"(216 intake 220 exhaust both 0.600" lift). I'm either sending the original 317 castings heads to Total Engine Airflow for there stage 2 porting(about $1500) or will use the Trick Flow as cast heads for $1900, Trick flow cnc heads for about $2500 or the AFR heads for about $2500. Don't need any of these parts to make the power I want with the cam size I am choosing, but I want to keep a small cam in it and max out everything else. Can always cam swap it later. I prefer to upgrade everything and do it once, regardless of how much more it costs versus a cammed junkyard engine. This engine is going in a 2005 Chevy Tahoe.

I have a 6.0 na that I put ported 243 heads on with ported tbss intake and cam. For a street driven truck it’s a lot to handle. I have thought of adding a turbo but I think 500whp is a lot for the street. Maybe I’m just old school, I remember when you had to really build an engine to make 500 at the flywheel now a stock 6.0 with a cam swap will do it. For a street driven car that I wanted to be quick I would go with the stock 6.0 or 6.2, change the cam then a small turbo with about 7lbs of boost. I think that would make the best all around fun car. I go ported heads on an na engine though.

D1x with 15 psi on E85. I tuned it on the street and it's a lot of fun. Hope to get it to a dyno when things get back to normal to see what the curves look like and how much power it's making. I hope to do heads and a completely different top end next year. I did this simply for budget reasons, but it seems to work a lot better than most would think.

[@flyonbyya]

If you’re gonna gap the rings, you might as well do heads n cam

[@mxguy2438]

My thought on the more boost vs more airflow mods thing, is more boost is going to increase parasitic losses from added heat on the cold side which may limit timing below optimal. It will also add parasitic losses on the exhaust side as backpressure rises relative to boost pressure. So basically, by not upgrading, youre lowering the ultimate limit of the motor and for a given power level, the non modified motor will be pushed closer to its limit and have a smaller margin of safety. It may also not spool the turbo as fast as a modified motor. The modified motor is clearly the more effective choice, but the non modded motor is plenty effective. So the decision on the "best" choice really comes down to thickness of your wallet.

[@DBSSTEELER]

Boost is also stress on engine parts. So building the na combo to make the power you want at the lowest possible boost level is only beneficial.

[@kennethpowers8995]

Boost level really doesn't matter, its power that breaks parts. It doesn't matter if you make 500 HP/TQ on 8psi or 14psi, the stress on the internals will be the same.

Cars with bad tuning is the biggest enemy. Not power level or parts

Just an awsome and informative video, even with the Mikes hard hic ups lol. Keep the good stuff coming . Im in the middle just want lots of power that won't leave me stranded.

Let the turbo do the work. If it isn't going to break don't fix it

[@davidbilliter5619]

My opinion ( everybody has one, lol) is if you are trying to make maximum power ON PUMP GAS , porting makes sense . You will be octane limited , so na hp will help make more power before you limit out on octane. Softening the chambers is important too , while your porting . Again, to help get by the octane limitations . You guys that have easy access to E85 live in a different world than us that live on 91-93 octane . If E was everywhere , and to make 1000 hp , I probably wouldnt waste my time on port work and chamber softening. The whole cam thing comes in too , even though most LS cams are ground to kill dynamic compression from the start . Wide lsas' help kill peak cylinder pressure down low . Overall, its just a whole different world , E85 vs 93 pumpgas. 1000 hp is almost too easy on E85. You have to open a whole bag of tricks to get close to 1000 on 93. My next combo , if I dont damage my 6.2 block going for power on 93, will be a 416 w all the tricks to make na power AND soften the cylinder pressure down low ( mutually exclusive , i know ,to a point . Compromises ) , then shoot for 1000+ on 93 at minimum boost.

Doing my first LS swap in a 86 short bed so going stock for now till I can get it running.. learning as I go need lots of help not a whole lot of cash flow to get it done

[@leepederson5254]

Want vs cost vs time. If you know what you want, assets the cheapest way to get it, if you have the time it will cost less. If you have the money it will save you time.

[@tobyparker8936]

It's all about how much money it's not about just the motor if you have a 1000 hp engine you also need a tranmission rear end and suspension that will take that much power

[@rongravel4585]

I always say. I’m just gona unshroud the valves a lil and just touch up the casting flashing. And I always end up porting the shit out of em. LS’s make tons of power with a lil port work.

From looking at Richard's tests, they really don't seem to add at whole lot. I mean when you only see a 20-30 hp gain going to rectangle port heads it sure seems easier to just go a little bigger on cam.
