Northwest Members - my new build

i guess its time to announce that im starting a new build in the near future.
so far this is what i have planned:

LSX454 NA
AFR245(mamofied)
fast 102/102(mamofied)
Custom Cam
dragon slayer crank
forged pistons and rods

im in the beginning stages of planning so i dont have all the details.
what im going for is around 630rwhp and 600ish rwtq(hopefully on the upper side of 600). it will be a street strip car of coarse. im pretty excited for this new motor. im hoping to have it in the car this winter. in the mean time, im going to install a:
9 in rear with 4:11s
new clutch
some tranny work
suspension
and a few other things that dont really need to be mentioned.
anyway thats it for now:pimp:

Did you hit the megabucks jackpot?!

Did you hit the megabucks jackpot?!

you could say that lol

so does anyone wana buy a built LS1?

That Sounds sick bro!!
Hopefully you actually do this one an not change your mind in about a month or so..lol...j\k
Let us know what your cam spec will be and you should call Jeff at EPS. If thats the route you wanna go.

Also how much for your motor?

thanks man! im pumped about this biuld. i dont think ill change my mind, i am set on going NA and this is the motor i have truely wanted for a long long time now. i love the idea of having all that NA torque and the 454 is the way to get it, plus it has those classic cubes. the only thing i might change is the block, i have heard some not so good things about the LSX block and that the best way to go is with a resleeved LS2 block but it is alot more expensive..but if im putting all this cash into a build i might wana make sure its not gonna fail.

Also how much for your motor?

im not sure yet, maybe like 3K

im not sure about my cam yet, eps would def be a good choice. tony mamo said he could help me with a cam. this build will be simaler to his 454, he will be helping me with a parts list.

Well if you do change your mind you should go 427 LSx that will get you there. I wouldnt resleve anything. Mike went through that and from what I remember is that the sleve failed. But that's just me.
And 3k for your complete motor? Or are you going to keep some things?

i remember the issue mike had with his resleeve job. some say the lsx block is the way to go...others say different. i thought about going 427, but im trying to get as much NA horsepower as i can not to mention torque, my second choice would actually be LSX440(which im still considering). i imagine i will keep some things off the motor but only little doodads like the coil packs and what not. tony will be putting a list together for me and im gonna go off that.

Before you pull the motor we need to run so I can blow your doors off.

did you hit the megabucks jackpot?!

+1....

Congrats on the jackpot. ;). I just learned a little more about these newer cars by lookin through the posts. I'm a newbie to these things. Was all about old school Pontiac engines for quite a while.

Nice man, looking forward to seeing the build thread. Thats the motor I've always wanted...I estimated my supporting mods with motor to be in the mid 20k range so probably not lol.

dont worry todd, we will run em for sure. im not even buying parts till late summer or fall. but i will be getting it running like it should soon.

thanks man, gotta love old muscle.

me too man, ive drooled over this motor for a couple years but never thought i could ever have one. the bitch of it is every mod i have done will have to be replaced, i have headers but will need new ones, i have true duals but will need bigger tubing lol, ill need a new lid even

I did the 454LSX thing, unless they have absolutely perfected the bore stroke combo I would do the 427LSX instead. If I had done that I may still have my SS now. I remember thinking how COOL it would be to have a 454, it would have been almost as cool to have the 427...

I wouldn't dump that kind of money into your F-Body Joe. If you can afford all that stuff you listed along with all the supporting mods, I would just pull the trigger on Vette or something equivalent and build off that.

This!! I personally wouldn't use any engine combo with a 4.1" stroke crank. The piston goes down too far into the bore and rocks (no bore support), causing piston scuffing and oiling issues. The LSX block doesn't have a long bore anyway so this compounds the issue. Stick with a 4" stroke (427) like Bobby mentioned and you'll be just fine. If you want good power, invest in good heads. I remember helping ya install that 454 Bobby. What was that, 6-7 years ago? Hard to believe it's been that long.

Sleeving blocks has come a long way since my old Darton wet sleeved block was done (circa 2002?). ERL does an amazing job with the dry new sleeved blocks and I would take an ERL sleeved block over an LSX any day of the week.

Mike

That new combo sounds like its really gonna move. Good luck punching the block out to 454, I hope it isn't too much trouble.

If you ever decide to sell the LS1 engine let me know I have an El Camino in need of one :)
Jessica

Hmmm, now I'm not so sure

Just build an ls7 and call it good!

Your f-body is paid for as well, not having to put the money down on a vette and then build it costing even more money. However a c6 zo6 would be sweet.

exactly, plus im just not a vette guy. id get a GTO if anything. c6 zs are nice tho.

i gotta figure something out, i was dead set on the 454. lsx427 would be my third choice

looks like 427 is the largest i could go with a 4.00 stroke. even a 441 uses a 4.125 stroke.

i have heard they have fixed the issue with the newer ones but im not sure

so what exactly happened with your motor?

i will be selling the LS1, motor has heads/cam fast and everything that goes with that. puts down 426 with ls6 intake and it sounds badass. motor has 68,xxx miles

i have heard they have fixed the issue with the newer ones but im not sure

so what exactly happened with your motor?

The bottom of the piston walls scraped and it went through oil, the new owner ended up building a very big bore short stroke motor out of it. If you want bigger you can go more bore to stroke than a 427 just keep the stroke at 4 inches max. The builder that did mine at the time was reputable and told me oh no you have nothing to worry about, then acted like it was my fault when it started drinking oil. It was a pretty bad experience and I was out of the "mod" game for awhile because of it.

Really the 454 would blow the drag radials through a mod 9inch at 75 miles an hour like it was no big deal. THat was with crappy (by todays standards) heads. I doubt you'd miss those extra cubes on the street and casual ET racing. But I here you 454 LSX sounded sooooo sweet, I even had emblems made :) I have guys that have them PM asking about the oil consumption every once in awhile and its not a happy ending.

Yep that is what happened to mine..ALOT of money gone and the new owner of the car paid to have the motor redone :( It was a little over 5 years ago.

man thats a shitty deal, im sorry to hear that. but ya it would be fricken sweet havin a 454. i could still have one if i go with the LS2 resleeve,but its gonna cost alot more. it would be alot easier just to go with a lsx427, but the 454 would be much cooler

What's cooler, having a 427 that you won't have to worry about or a 454 that might have some problems and end up costing more money when shit starts going wrong?

The issue isn't with the lsx block its the stroke being over 4" meaning the piston has to drop below the cylinder each stroke and it scars the pistons. I would say a 427 would be the way to go.

i understand the 4.00 in stroke thing is causing the problem, but isent the other half of the problem something to do with the cylinder walls also being too short on the lsx block? it seems there is mixed reviews on the 454 engine, some people say they are garbage, others say they have had no problems with them at all..but its not something i really take a chance on.

i may have figured out the next best thing, i can have a lsx440 shortblock built with a 4.00 stroke..so i guess thats one way to solve the problem

There you go, I was going to write earlier that I think the bigger bore shorter stroke builds are some of the best and the LSX allows you to go pretty big on the bore. That is what I'd do in your shoes.

ya i think thats what im gonna do, 440 was my second choice anyway and now i can have the 4.00 stroke as well. its only 14 cubes less afterall

just talked to A guy at ERL and i like what he said, i feel alot better about having a 4.125 stroke after what he said:



Our sleeves are longer and are 5.800 sleeve length. With you supplying a good core LS2, LS3 or 5.3 block we have three options for you.

#1 - ERL Dry Sleeve 4.000 to 4.185 bore w/arp main studs, finish cylinder hone and align hone = 2250.00
#2 - ERL Superdeck 1 (4 bolt)4.000 to 4.200 bore w/doweled billet main caps, arp main studs, finish cylinder hone and align hone = 2900.00
#3 - ERL Superdeck 1 (6 bolt)4.000 to 4.200 bore w/doweled billet main caps, arp main studs, finish cylinder hone and align hone = 3500.00

Having ERL sleeve your block and honing it to get big cubes is not that expensive in relation to other options. We have plenty of core in stock that are already sleeved and cores you can just purchase outright if you don't have a core. Having us sleeve the aluminum LS OEM block also saves you a ton of weight and our cylinders are much stronger than the LSX iron block and RHS cast iron sleeve blocks.

Our turn around is pretty quick right now and is a great option. Just let us know how we can help. Thanks!

ERL>LSX,,, ;)

i feel a hell of a lot better about building a 454 with that block...i could even build a 468ci if i wanted
