Good work, that torque curve is going to make a lot of fun/smoke….

That’s awesome. And I was only 12 hp off

That’s on my ECU,  “should” drop it in, hook it up and hit the loud pedal.  Tbh before with ~600 it was mental, I am not sure what its  going to be like with 150 more, but can’t wait to find out.  Just so pleased with it, very satisfying assembling it myself, and hearing it.  The phone sound doesn’t really do it justice, happy days!!

Start and idle

Nice stuff mate. Did intake limit it from going to 7000? What’s the power/torque like around stall size?

No Cav, the intake starts to choke it after 6k.  It would I think easily make over 800 if it could spin to 7 which it is capable of.  But that would mean a different inlet manifold which I am not doing.  I spoke to Brenton and he thinks the torque converter will be fine for street stuff as it is.  My plan is to drive and enjoy the bloody thing for a year, then let’s see.

Nice result and im glad you are keeping what it was designed for in focus.

 

Should be a fun thing to drive

Thanks, Sands, yea very happy to see how nicely it starts and idles, I just did the conversion and that’s 930Nm of torque, multiply that through the drivetrain and its going to be quite a torque monster, which is what I want.  Happy days.

Anytime one makes it off the dyno still in one piece is a Win

Lol, yea my heart was in my mouth I have to say.  First time I have ever been involved with an engine dyno, I think its the way to go if you can.  Quite a few little niggles we were able to sort out quickly, that if it was in the car either would have had us scratching our heads, or much been more difficult to get access too.  Now when I get it back in, I know its good to go.  So if there are any gremlins it can only be in the car loom or whatever.

Awesome result. lots of 454 builds around that same power, its hard pushing the 454 beyond tht power level without going max efort

Are you sure the intake is holding it back? Ive seen cars running the same intake putting out 510+rwkw.

Yep, 100% its the manifold, you can see it in the manifold vacuum.  Actually, Brenton just did all the maths on the numbers and it should spin quite well to 7,200.  It made up 150hp from 5-6k rpm, so who knows what its got in it.  my guess well north of 800hp, maybe 825.  It’s a streeter, that’s enough.  In all honesty anything over 500hp and it’s a pissing contest, no street tire will hold what its got.  And it’s not just the power, it’s making 684ft/lb, 625 ft/lb at 4,000 rpm.  It was brutal before, I am stoked.

[Vehsv454Participant VictoriaVe hsv Senator View build HERE Member since: February 12, 2019 Posts: 15]

The best bit is it will still be punching lots of torque at wot, id expect 570ftlb

Would feel better bolting it together as well!!

my engines been out about same time yours came out, ill have mine back in a few weeks. Was interested to see what yours achieved. My goal is 500-520rwkw. Should get there ,but u never know.

Wow, that’s like 900 fwhp right?  NA?

[Vehsv454Participant VictoriaVe hsv Senator View build HERE Member since: February 12, 2019 Posts: 15]

Roughly 900fwhp…. I think we are slowly working these engines out. I started with my original block with darton midsleeve 454, rebuilt tht a few times before darton finally said to much power twisting the block.

Then went to the lsx block, had similiar problems to you. Bad tuning from so called good tuners, washed the bores a bit ,leaving hot spots. not using roller rockers causing valve stem seal probs, blowbyGot it to 420rwkw with Ls3 heads and a fast.

This time around we have gone balance crazy with harmonic balancer, flywheel,clutch balanced with rotating assembly, solid roller, tony mamo ported heads and ported msd intake. I dont know how much we will pick up over the ls3 heads ,hoping around 50rwhp, the ported msd intake in comparison test show around 40rwhp over a ported fast, and the solid roller cam should get 30 odd… even the new low volume oil pump will pick up 5-8rwhp.. Once the engine run in  ill put the aviad dry sump set up on and will gain a bit there as well.. The but is i know of a few different builds where they couldnt get past what power you will have now, bout the 430rwkw

Can you notice the difference between hyd roller set up and the solid set up? Sound different? Was looking very smooth in the vid vibration wise

Sounds like a bloody awesome piece of kit mate!!  It’s a bit hard to compare the sound at this stage, as the whole set up is different really, it’s making roughly 150HP more than before so it will always sound different.  I was surprised on the dyno how nice it was at idle, given the large lift and cam specs etc I expected it to be rougher.  The cam is a low lash roller design, which is specifically designed for the street to be much quieter and should see 15-20k miles between needing to touch it.  Given I will be lucky to do 5,000ks a year, I am thinking the reality is maybe each winter I will do a major “service” and on that list will be doing/checking the lash.

[Vehsv454Participant VictoriaVe hsv Senator View build HERE Member since: February 12, 2019 Posts: 15]

It really doesnt take much to whip off the rocker covers to check lash. 30mins and done

On mine i’ll be replacing springs every 20,000kms.

glad your happy with it and hope we cross paths oneday for the 454 senator shootout lol

Love the sound of this thing.

The engine is now safely unloaded and tucked away in the shed.  Might need to do a bit of a stocktake and make sure I have everything for the reinstall, it’s been so long since I pulled it out    Super busy at the moment so not sure when I will get a clear go at it.  First step I guess is to fit up the trans then drop it in the K frame.
