LSX376 Users - Come In
LSX376 Users - Come In Buddy of mine is considering a LSX376-B15 and wanted to get some feedback from anyone who is running one or know details of someone running one. Considering a stage3 turbo cam and twins and looking for a relaible 900-1000rwhp. Lemme know your FI combo, estimated HP and any feedback, negative or positive.....tks.
That shouldn't be an issue. Change the cam as outlined then I would make sure to put ARP head studs on it. They come with factory head bolts that I wouldn't trust at that power level. StangKilr on here - Justin Keith the dude that puts on all the SCT events made like 12-1300 rwhp with one and those 2 mods in his silver camaro that he has since sold.
B15 out of the crate, Holley Hi-ram intake, 95lb injectors, A2A intercooler and twin Precision 62/66's. Made 1000 wheel horsepower. Car had a powerglide with gear vendors overdrive and 3.89 gears with 31" tires.
Best ET was 8.48@156 if I remember correctly. Pretty sure he had it turned up to 22 or 24 psi that day, but he normally ran it at 20psi and was running 8,60's at that psi.
You are welcome 2JZFC. Yes, exactly as it came from the crate. He did run less boost the first season to make sure everything was well seated and turned it up over the years. It still ran great when he pulled it, but he figured with probably 200 passes or more and thousands of street miles he would freshen it to be safe.

I ran the lsx376 b8 in my 5th gen camaro and trapped 158mph in the quarter at 4100 pounds multiple times. Elapsed times sucked becuase I couldn't put full power down till the 660ft or so but it did that forever. Mostly street speed contested. If a lady hadn't ran a stop sign and wiped it out probably still would be.
I changed to a tick stage 2 ls3 turbo cam and ran ARP bolts instead of the stock ones where the only changes I made internal in the engine. Hell I even used the stock head gaskets just changed the bolts out one at a time. It's a damn good engine and you have a leg up with the b15 already.

If you can pick one up, add head steads and reliably make 1,200-1,300whp then that sounds like a pretty excellent deal especially when you consider GM engineering is backing it.
I read an article a while back that said when they test these engines they run them from peak torque to peak horsepower for 24 straight hours which is bonkers to me.
Is there another crate engine in that price range that is comparable?
Man, Holley sure is proud of their products!
The hi-ram might present some fitness issues as the hood will not be cut, scooped, etc. Owner has a preference for Holley products, so can someone explain the differences between hi, mid and lo-ram as it relates to how they affect engine performance, i.e., throttle response, low-end torque and top-end. 3,800 street-driven (not a DD) that will see track maybe twice a month. Will probably have twin billet 6762s and shooting for 900-ish RWHP....for now.

From everything I've seen the low ram is a pig every where in the rpm range except at peak.
Everyone seems to run the high ram for these reasons unless packaging is an issue.
I'd look at the BTR Intake or the Shearer LSX Surge Intake, the surge is sexy AF.

The btr and shearer are basically the same and also short runners which are designed for 6-8k rpm just like the lo ram
if your looking for torque and peak power in the 6-6500 range you might want to think about a fast or msd intake
