true dat
"there's no replacement for displacement"

 

500rwhp has been done a half dozen times with a 346. just the right combo of parts.

however, the easier way is with cubic displacement. but big cubes is no guarentee for 500rwhp either. the right combo of parts is also neccessary, your power is going to come from a good h/c/i combo matched to your application and powerband.

 

I don't even think a stroker will do it... just add torque and not much more HP. I think you can do it with a re-sleave to say a 427... But why worry about 500 rwhp N/A? If you're putting down 425rwhp N/A and spray it with a 150 shot, you'll have your 550+ when you want it, and get away for about $5000 less than rebuilding the whole engine. You might still think about swapping out your stock rod bolts for Katechs, but you could leave the rest of the bottom end untouched. Believe me, with 4.10's and a radical cam, plus the heads, intake and bolt-ons to support it, you'll forget all about numbers... tire shredding monster, dude!

 

Were those half dozen times all solid roller?

 

nope, not the ones im refering too. TR, Rapid, Cartek, LGM, A&A, TTP, all used hydraulic rollers. Futral used a solid roller though.

 

Yeah you really know what your talking about. That why you posted this thread in the first place. If you already knew the answer to your question then why did you ask it?
Oh thats right because you had no clue what you were talking about thats why you posted this....
"what is the easiest/cheapest way to 500 rwhp all motor. nitrous will be add on top of that. i was thinking that ls6 heads ported and ls6 manifold ported to match with all the bolt ons and a cam would get me there. i want something i can still cruise in with decent street manners and take it to a track day every once in a while."
Yeah you really know what your doing. LS6 heads, with LS6 intake, bolt ons and a cam. Not a certain cam just a cam, but one with decent street manner's.
I would have never posted this reply if you wouldn't have been a dick head to the other members. If you newby *** would have used the damn search button you wouldn't have posted a retarded thread. Dont be a dick to the member that are acturally giving you good advice just because they are being a smart ***.
Do yourself a favor and get in good with some of these guys and learn so your next threat dosen't make you look a dumb as this one did.

 

402/408 with good heads, 244/248 cam, fast 90/90, and all bolt ons should rock the 500 number with a good tune

 

Man . . . I'm surprised that 99% of the people in this thread don't know that 500 rwhp Heads/Cam and UPGRADED bolt-ons is not ony possible, but has been done already.

I know JRP already stated as much but dang . . . some of you guys posting in this thread have been around a while . . . I at least expected Lyle to know as much

500 rwhp N/A 346 is by NO MEANS easy; but it is doable.

I'll let you guys know how close it is on my set-up in 2 weeks

Lyle, when are we gonna run motor for motor??

 

I would start with a set of good heads like AFR 225 small chambers or ETP 225 or Darts.
Then fly cut your stock pistons and add rod bolts.
Fast 90/90 intake and a lot of gear
Then next match your combo with a lager custom cam.

It can be done if you match up the correct combo, look at Patrick G. he is close with only a small set of AFR 205 heads and mid size cam.

Just wait, with all these new heads coming out now and new intake being designed; there will be a lot more 346ci/500hp street car out there soon.

not cheap though. not gonna happen cheap. and with a 109 LSA, you'll be prone to intake backfires if the dope isnt properly tuned and it will take you more dope to make the same power because so much of it will get sucked right out the exhaust valve during overlap.

 

In my 2000 Camaro SS I did 475hp and 512tq with full bolt ons (still ls1 intake) and a 150 shot, M6 car with 12 bolt and 3.73 gear. So i would say a mild heads and cam will get to where u want to be.

Note: The red line is customer's previous heads/cam package from another shop.

It's been done and can be repeated.

Details on the car:

1998 Camaro, MN6.
3.5" Alum Driveshaft
9", 35 Spline Axles, 4.10 Gears, Spool
TTP Stage 4R Heads/Cam Package (Hydraulic Roller)
LSX 90mm Intake + NW 90mm TB
Kooks 1 3/4" to 1 7/8" Stepped LTs
True Dual 3" to 2.5" w/ Dynomax Ultra-Flo Mufflers
Stock Bottom End w/ Pro-Series Rod Bolts only
93 Octane Pump Gas

I would say this combination would make around 515-520rwhp easily on a stock rearend.

 

I'll be lucky to get 500 rwhp with my set up when I'm done. Then again, I'm just looking for a 10-15 hp improvement

 

402ci/408ci LS2/Iron Shortblock from a reputable company (FMS, etc.)
Good Flowing Heads (AFR 225's etc.)
Custom Cam Spit duration, Wide LSA for NOS Application (EDC, OR FMS etc.)
Fast 90/90 Intake manifold
Final Compression Ratio around 12:1 to 12.5:1

and ofcourse all bolt-ons and free mods and lots and lots of tuning (HPtuners).. this setup will be reliable and about 500-550rwhp (all motor) depending on how wild the H/C will be + u can also spray 100-250 Shots of Nitrous depending on the spark plugs and how much degrees of timing ur running.

note: you can do 500rwhp in a 346ci (very wild H/C setup), BUT:

1. it wont be reliable
2. it wont be a good daily driver
3. it would require a BIG stall
4. it wont have good torque

 

I would have to agree!

 

I don't know about reliable, but 2 -4 aren't a given...

Does anyone with 4.10's or higher think they would have a problem with torque??? The problem is hooking up, not too little torque. As for the big stall, get an M6! If you don't have any torque problems, and you've got a good tune, where's the driveability issue? Also, I suspect a lot of guys would say "daily driver" can be a wild ride; can I get an Amen, here?

 

second that.

 

150 wet shot.

 

i went a little overboard with my last post but i had little help and mostly sarcasim. thanks for the other responses i guess it looks like more cubes or a little less power on just motor and some nitrous. i'll probably go with latter for now.

 

408 iron block

Check out LME (sponsor). They build quite a few of these motors.

You should get 500 rwhp with the right set of heads/cam combo with a 408.

Other than that, its hard to get there with a 5.7L unless you go with a solid roller cam. Then there goes your streetability...
