454 Cu. In. LS2

[housewolf]

Hoping to have this in my car in the next few weeks and ready for the track by the end of January. It's being built here in Houston by HKE -

Wiseco Pistons, Callies 6.125" rods, & Darton sleeved 4.185" bore LS2

It will be naturally aspirated and hopefully ~600 rwhp. Enough to consistently run 10.3s.

Assembled shortblock -

That's similar to the route I'm going once I clear out some garage space (don't ask) only I was planning to use a stroked LS7 casting and 285cc cathedrals.

Is that a fresh casting or is that your OEM? I've heard resleeving is hit and miss. That combo should net you 600 easy, plenty of people are hitting that with the 441 LS7s and "touched up" heads.

Are you going to go with the 441 LS7? I was noticing that TSP's stroked LS7 shortblocks are actually cheaper than their stock displacement LS7s. I guess the crank is the price difference?

My eventual goal is a wet sump LS7 in my GTO.

[Infernus]

The 441 from TSP yes. It must be the crank like you say, since the OEM LS7 crank design is a long snout for the external oil pump on the dry sump system. While a dry sump would be cool, there's probably no reason to reinvent the wheel in our case. It's wouldn't surprise me if the extra bit of material and machining made up for the price difference. :dunno: Hard to say though, since it seems like there was a drastic price drop on the LS7 casting this year compared to last. I seem to remember a bare casting being almost $6k and now you can get a shortblock for around that price. Either way it works out for us!

[Robofuzz]

When are you planning the build? I am assembling miscellaneous parts and storing them for the day I save up enough for an LS7 shortblock. In the meantime, I am upgrading my suspension, fuel system, etc.

Hopefully more hit than miss :eek:

Not my OEM but it is a 6.0 L from a GTO. They would rather resleeve a used/stress relieved block than a new casting.

I don't know how many of these HKE has done over the years from RED & ERL but I would imagine it is in the high 100s if not more. There are about dozen in their shop at any given time. If Erik has faith in it, that's good enough for me.

The sleeves are honed with torque plates in place, the deck is set/surfaced, to the pistons used, the main bores are line honed, & rotating assy is balanced. There was more to it than taking the block off a pallet & the parts out of the boxes and assembling pieces.

A year went by from the time I decided to do this until we actually got started. At the start it was going to be an LS2 block w/CP heads, at one time the plan evolved to an LS7 block. Between the difficulty of finding a "suitable" (and affordable) donor block & the issues that would have to be dealt with on the LS7, I got impatient & went with the LS2 block.

At this point, there is a valid reason for the selection of each component used, be it budget or performance driven. How it all pans out pushing the car down the track (or street, this car is still a "street car") is yet to be seen.

Thinking late 2012, probably after deer season/thanksgiving, since my garage pretty much turns into a butcher shop, and I'm being a good friend letting my buddy store his 18' bayliner and a bunch of other junk in my garage while he wraps up his divorce. :popcorn:

:banana: Good choice, people often overlook that very (IMHO) important step.

If they've done a bunch of resleeves I wouldn't worry about it. I would be leery if the guy had only done a handful though. Those heads you've got have huge runners, I'm interested to see what you get with low end out of those, but I can't say we've seen may of these monster Gen III/IV smallblocks out there, usually 418s are the biggest you see, if any at all. If anything, seems like the general rule is to go big on heads and milder (not ridiculous, I mean) on cam duration, and you should get great flat tq curves with a quality tune. What kind of induction are you planning to put on top?

I'm doing ITBs on top of my heads, probably Harrop since Kinsler doesn't want to return my attempts to contact them for some reason. A lot of people have poo-poo'd individual throttle bodies for the price you pay (that's sc/turbo money, etc) but I think it could give great results with a stupid big cam.

I'm not ready to let all the cam specs out of the bag yet, but intake duration is in the mid 250s.

This car is an A4 with a high stall. As long as it has enough torque below 5K to keep the car rolling, that's all I care about. We're looking for the power on top. I'll be spinning it to 7250.

OEM LS7 intake/ LS2 Throttle Body / LS9 Injectors

ETA - Someday in the future, I may see a single plane intake with a 4150 TB but I'll start with this. I can't deal with the pains of dealing with getting rid of DBW using the OEM computer at this time. I don't know of anyone that's done this but I don't see it as impossible.

[Robofuzz]

Can't wait to see the results! Be sure to post lots of pics of the build!

Going to manual throttle shouldn't be too difficult. Just isolate the 3 wires to the TB that send a TPS signal and splice them into whatever aftermarket unit, and tune accordingly (shut off MIL, AFR correction & main spark advance if you feel like it). And a pedal assembly out of an '04, of course. If you've got the inputs to the PCM, missing some outputs doesn't matter other than it getting pissed at you for eliminating some stuff... but telling it to "shut up" is easy :gr_jest: and shouldn't prevent it from running any monitors for passing emissions.

I'll post what I can, this is the thread for this build.

[housewolf]

Bringing her home tomorrow. I hope to have it in by the end of the weekend and tuned by the next.

LOOKS AWESOME!!! Check out the new NA PowerChamber if you have any questions let me know. I love my 454,awesome tq

[housewolf]

It's home & in my garage now. Install will be Sunday & hoping to tune Sat 1.21. I'll try and take some more pics on the stand & during the install.

[Daniel Linnett]

oh heck yeah cant wait to see! I will have to come out and watch you run and maybe even bring mine out if she is ever running to her potential

[housewolf]

...if she is ever running to her potential

Wow! What a line.

There was a time I realized my old setup would run about 10.85 if I could reach that point. It was about three years later before I did (10.80), then I decided it was time for something else :)

I really think this setup will go ten flat if it makes 90% the power we think it will. I sure don't expect it to run that first time out the box though, not to mention I have a totally unproven driveline to worry about at this power level. :confused:

But who knows... it may run 9.999 first hit ;)

We still have a few things to button up but it shouldn't be a problem making our date with the dyno in a week.
Huge thanks to the krewe - Chris, Dave & Tommy :hail:

Yeah man that looks really nice. I'm excited to see what you get with it.

[magnum-gto]

You're doing some interesting stuff here! Just curious, but what is the static cr?

[housewolf]

I don't remember exactly, it's just a little below 11.5 though. Either 11.48 or 46.

We went to the dyno Sunday and performed poorly. The tires spun & converter slipped; but... it is tuned. I figured the converter would slip too much, it was borderline with the 364, but performed well (10.80). I lost about 20 mph in slippage compared to the old engine. Best run was 520 rwhp with MAP 92kp. I can't believe it'll slip that much more on the track, maybe it will :dunno: so I'm going to take it out tomorrow and log some data then order a new converter (if needed). A better intake & filter will take care of most of the MAP issue, but we'll probably leave a little on the table with the LS7 intake/LS2 TB.


See tire spin -

[Poolshark1321]

Haha very nice Housewolf... hows she running at the track? Any more video?

[housewolf]

Thanks.
I had it back on the dyno a couple weeks after that and it did ~560/540 on a Mustang Dyno with an unlocked converter.

10.3 @ 130 on the track with the interior in the car so I met my goal first time out but I'm still doing a little tweaking. I imagine best case would be to stay the same as the conditions go away.

[ram09]

I think your leaving hp/tq on the table with the factory LS7 intake & definitely leaving it there with the stock throttle body, but very nice numbers, how many miles have you logged on it so far?

[housewolf]

Very few miles... maybe 50 & 8 passes on the track. Still working on a few tweaks here and there.

I really don't think I would pick up much with a 102mm TB. Intake restrictions can be measured by MAP, I'm seeing 98+ so there isn't much there. Gains with a FAST 102 on LS7s aren't consistently as much as with our LS2s. The LS7 intake is a very good intake. Granted I do have more cu. ins & a big cam so my gains would probably be on the higher end. By the time I get a FAST, fuel rails, & 102 mm TB it's close to $2K and I no longer have the "stock" appearance under the hood for ~30 hp at most. In mineshaft air I think I can get a ten flat with it as it is. My safety equipment is only good to 10.0.

[Poolshark1321]

^ If you port the LS7 intake and TB... nobody will ever know or be the wiser. I am sure you have already thought about this though.
