A couple notes on this: Yes, you CAN make more power with a turbo setup, or going with a 6.0, or whatever else. However, this test was done in the interest of proving that there are many ways to gain power. Hot Rodders have been building 383's for decades and making great power from small block Chevy's. If you're interested to see what doing a turbo setup would gain you, check out our LST Turbo Camshaft test video from a couple months back!

Seems like the way to go for the money. You have more displacement than the 6.2 and half the money. Plus you can gap the rings and set it up how you want... good stuff!

Very professional I love your videos or learning lessons

I ran this cam in a stock long block lq4 once, and it made way more power than it probably should have with that little bit of compression. LOL

Richard, How about building a stock 4.8/5.3 4inch stroker with stock cam and then add stage 1,2 & 3 truck cams. This would be a good towing motor and should be equivalent to a 6.0 block that you tested before.

Have yall done a test on what the accessories use and is it more of a flat rate or a percentage

I built a 5.3/383 stock heads a comp cam valve springs it made right at 500 HP almost same torque

To get the 4.00 stroke did you use the ls7 crank, and if I decided to go with bigger pistons could I use this same cam or would I need another , and would it give me more hp ,and would a turbo make even more hp with either application?

So do we need to run a fast intake or can we run the TBSS intake and gain similar results!

Really, great explanation. But with my illiteracy, all those indecipherable words got in the way of the story. The pictures did help, though.

Hi Richard, question what do you know about boring out aluminum gen4 5.3 to 5.7? seeing videos about the gen 4 being able to support the 5.7

Can you please start a series on Gen V LT motors ??

Contemplating an LS swap for my car so it's interesting to see different combos and setups. While turbos produce impressive numbers and seem the more popular choice these days I'm not sure that would work for me as I would like to try my hand at autocross. Thanks for the info.

Doing the same

As the adage goes there's no replacement for displacement. Although turbos and forced injection are starting to change this.

Why is cam quest 6 gone from the website to download I loved to run tests with cid, custom head cfm numbers, intake combos with different cfm and camshaft options. Food for thought.

OK what did you do to the crank ? Throw it out and get a new one or have it machined for the bigger stroke ? And what are the connecting rod sizes, rod and main bearing sizes? Do you have to have $2000 fast xfi management system ?

The Combos, is it for a truck application or car?

So does the 347ci displacement from the 5.3 have a stroker crankshaft or stock crankshaft

Nice

is there a parts list, or kit or anything? what would we need to do this turn key?

is there a good place to get the bottom end components to build a 383 out of a lm7? as well as a parts list?

That sounds great. But what was the cost?. Some guys are looking to build hp on a budget. But it would be nice to see cost aswell.

What stroker kit did you use

Where do I get the stroker kit for a 5.3

Will a 383 made out of a 5.3 be reliable long term as a daily driver also will there be cooling issues with the motor bore being enlarged that much. Also say I just wanted to punch out my 5.3 to a 5.7 ls1 and I already did a cam and head swap on my 5.3 to a BTR truck Norris cam and 243 heads I know the heads will work good but what about that cam? Will I need to change it after making it a 5.7?

could you safely run boost on this stroker set up if the block gets sonic tested and running on e85

Did you have to use the 383 stroker rotating assembly?

Where do I find a stroke kit? Which one did you use here?

What was the compression on this set up?

What stroker kit did you use?

What kind of pistons. I just found out summit has a cheap kit for 5.3 It’s a 363. 4 inch crank and 5 over pistons. But the guy didnt mention valve relief. I really like the idea because a monster 4 inch crank. Bigger then the 400 sbc and good heads. I believe you said 706 heads.

Did you make that power with a stock bottom end?

Is there a cheaper option for the 5.3 that uses a stroker crank but still uses the gen 4 factory rods?

Guy like a freakin Ninja.

5.3 heads can supply way more airflow than a 5.3 can even use in a street usable rpm range I wonder what the stock 5.3 heads could do with just a stroker kit and cam with stock cylinder heads

I like the idea of a 383 stroker 5.3, but I live in California. Can I build a 383 stroker with a mild cam and still pass smog? It's for an '06 sierra with an L59 (flex fuel LM7). Thank you for any insight.

Can you boost a 5.3 with a Bore that big and what if it’s a aluminum block. I acutely just aquiard a 4” crank and trying to finger out if I’m going to use the aluminum 5.3 block and save a bunch of wight or go put it in a iron 6.0 block. I have both it’s a race car 3275lb it’s been 9.88 with a 4.8 with cam and turbo but I want to get the car to it’s new chassis stickers limit. Lol.

Will it run on pump gas and what was the compression

Do you think you can make more hp with a turbo set up with a 5.3 ls stroked out to a 383

The cam used is the comp 54-454-11????

What fuel are you using

Can you do this to a 5.7 and just have a bigger bore. I would say 6.0 for a 4 inch bore but there hard to find

Hi Richard what was the mdl# on this cam?

Why do 383? I've heard people will stroke the lm7 to 347ci max and make the same power with just a bore difference or buy lm7 stock size forged internals and build a boost 325. Plus isn't going for 325 ci to 383 ci dangerous for the skirts in the cylinders? Or am i wrong?

Im doing eagle 366 rotating assembly 799 heads .ELGIN E1257P cam low boost twin 177275 bw turbos. Top 7.5 pound BOOST pump gas .Build to last pull car trailer etc. Turbos should last long time.

@michaelsantosuosso7284

5 ай бұрын

It's just an LS1 piston .010 over roughly. Not an issue, the issue is getting pistons with shorter skirts not to rock at bottom of stroke out of the cylinder. Wisco will make them for you, but I think already making them.

For the 5.3 Stroker build, what Piston/rod/crank was used? Also I want to go with Holley Sniper instead of the FAST intake - can I still get close to 600hp? Lastly I want a daily driving beast; hidden in my patina 67 C10, what combination do you recommend for 5.3 GenIII?

Got a build sheet for how to build this?

Be very careful. People have been known to do this and end up pulling the skirt out of the bore and snapping rods. Look up the video by Tom Nelson Racing engines "Why is the LS so good" and you'll find out why. Unless you are running an RHS block I dont suggest this. You rock that piston in that cylinder just once and your motor is history. Just something to consider when picking out which piston you are going to run.

@masta51

The 3.9 has a lot better options and 580-590 hp so leaving a little more on the table for a conventional ring pack. The 4.0 slugs now on the market move the rings tighter up high and removes the skirt so it's less likely to rock in the bore. They should have just went to a 6.0 or bbc 8.1 if they want to make some real power.

I wish this would have just been a stock vs stroker comparison with everything else being the same. When you toss in a cam, ported heads and an intake to the stroker, it's no longer a legitimate or fair comparison.

It would lower the compression but just have the heads milled or run a thinner head gasket. 243 is a better head.

The problem is going to be piston rock when that increased stroke pulls the piston out further at BDC. Those who run these strokers long enough on the street are reporting these issues at refresh time.
