Improve Horsepower and Torque: High-Performance Tips For LS Engines - Engine Power S7, E16

Love watching Pat and Mike they got to have the best jobs in the world, I wish PowerNation would do a yearly contest and let a winner come in to the shop and Rebuild your motor

[@tenman7242]

That's a great idea.

[@killacash199]

Putting a carb on an LS may be the "easiest" route, but certainly not the cheapest... Wouldn't the cheapest be all stock with the factory GM ECU flashed with HP Tuners or something?

[@joew7897]

Exactly. Over $700 for the intake and ignition stuff then they drop a $900 carb on it. For around a $100 flash to a stock computer you can drop in all the stock stuff.

[@killacash199]

@@joew7897 And retain your EFI, which is FAR easier to add boost or other power adders. So if you spend $500+ on an intake and ignition system, then another $400-600 on a nice carb for it, you're in Holley terminator territory. Which makes it even easier to have EFI that has built in capabilities for nitrous or boost, or whatever you wanted to add to it...

[@nate0765]

Probably the only way its cheaper is if you scored on a cheap long block, already have a carburetor sitting around, and don't have the intake and fuel injection setup.

[@baggedmazda666]

If ya can’t tell products what where supplied by different manufacturers steer how the episodes go lol. How they gonna sell these parts if you got someone like Matt that comes in and does a dirty half ass build on a junk motor and makes a reliable ~800hp for less than they have bolt on parts

[@killacash199]

baggedmazda666 Oh for sure, wouldn’t we all love some sponsored parts?😂 I also subscribe to the sloppy mechanics train of thought. Quick and dirty, but functional. Just be sure to add ring gap😬

I agree, I want to see junkyard pull, no pulling a part to clean the block or ring gapping with just a 228r on 110° with bee hive springs and chromoly pushrods with just a trunion upgrade, long tube headers and a fast 102 intake with a Nick Williams 102 tb , I do believe that would shut up the neighsayers as to a true junkyard bolt on engine then be honest like the rest of the LS tuners and give it the beans, you will be shocked as hell to see the results.

[@TrumpsEarBandage]

They scared of computers

[@79tazman]

You can get lots of power out of those junkyard LS but if you gonna run a power adder like a Turbo that thing you gotta do is gap the rings because if you don't gap the rings and get high on the PSI she will squeeze the top of the piston and that will be it but once you gap the rings your safe to add the boost

[@demonic4774]

If you want to run a LQ4 truck block for a drag racing application get one that's been rebuilt at the very least. the pulls are fine for street driving and will give you years of service but not when you add high flowing heads and intake the old bearings seem to eat themselves quickly . If you buy a rebuilt one you will have a solid start that will make tons of power for cheap. it pays in the long run instead of having to keep replacing the pulls blocks every time one eats it's own bearings.

[@mike93lx]

Agreed. Cam makes more sense to do first considering the cost

[@zachawge8576]

With an LQ4 like this, on 93 with an intake (TBSS or LS6 for the stock intakes), long tubes, BTR cam and valve springs (otherwise completely stock heads) you should be able to put down 405-420hp no problem.

[@zachawge8576]

36 years ago my Dad owned a auto salvage yard. My first build was a Chevy Monza Spider with a over heated factory motor. I swapped in a 302 chevy that was built. See my dad would not allow me to stick a 350 in because he thought cubic inches would mean to much horse power. Haha. Swapped out the engine and went to the track 110mph in the 8th. Scarry as hell.

[@chrisdavidson6519]

I want to see if you have a budget build and don't have the means to do fabrication. Like if you have to dent the header to get it to fit around a steering rack or other things of that nature, does it effect the flow and hp.

[@jameswiz]

Also, I used that same timing setup with a Melling HV295 Oil Pump (with the spacers) and had issues with the pickup tube needed to be extended. Then the pickup tube boss, as well as the oil pump bolts all hit the timing cover. Finally the "slosh tray / oil baffle plate" in the bottom of the oil pan then hit the pickup tube once it was modified to move forward the 1/8"... You guys didn't discuss any of this...

[@mathewshackelford8037]

the instructions for the timing set mention the bolts hitting the cover. This is just another reason NOT to run a double roller. It's an absolute waste of money on a LS. Guys are making 1500hp reliably on single chains.

[@jameswiz]

I wish you guys would test these using the stock intake and injector systems. That intake and carb would change the HP/Torque numbers...

[@jameswiz]

That's fine if you want a single Chain. I'm an old-school SBC man, and would never run a single chain, in any one of my performances builds. Seen too many fail (or JUMP TOOTH ONCE A LITTLE WORN) with extra spring pressures. Singles are not my favorite..

[@cncracingheads]

I've Dyno'd more than 300 LS engines. 24° ignition advance is not enough timing for a Truck LS on 93 octane, and didn't give the baseline test a fighting chance to prove what HP it's capable of producing. The MSD box comes with several ignition curves Pre-installed, and having more ignition timing than 24 degrees. What curve(s) were used for all the tests? If it was 24° across the board, you left a lot of horsepower on the table for all the tests. CNC Racing Heads.

I had no idea on an LS engine you can run a carburetor so if I was to put that in let's say my 76 Chevy 4 wheel drive I can run carburetor but then on the Ignition since the 76 has a distributor I will have to run like an msd Ignition set up or what? Same with timing how do they work on these LS engines🤔🤔

[@bilbobaggins4710]

Yes you'll need the MSD

[@paulmccoy2908]

The MSD is way easier to set up than a distributor. Just plug it into the stock sensors and coil packs and give it +12v the same as a distributor. I’d consider keeping it EFI since you can buy a standalone computer for about the cost of a carburetor and intake. LS engines are dead-simple.
