ok i'm not currently a 500HP club member but hopefully one day i will be anyways anyone here have a 3rdgen pushing 500HP and if you do what is your engine setup? and what do you run on the 1/4?

94-6spd

Here is what my setup is. I am putting it into my car this week so I don't know the et yet.

chevy 400 bored .030
balanced rotating assembly
H-beam rods
Probe Industries forged flat top pistons
Total Seal Gapless Rings
Nodular Iron Crankshaft
TPIS ZZX camshaft
Comp Cams retro-fit roller lifters
AFR 195 heads
Jegs 1.5 roller rockers
Victor Jr. intake
Demon 750 carb
10.4 compression
NOS sniper
1 5/8 heddman headers
custom y-pipe to a flowmaster
"Neal Chance Racing" 3000 stall converter
custom built 700r4
Richmond 3.73's
Auburn Gears Posi-trac

Both AFR and TPIS say this is worth st least 520 to 530 hp.

Hey 94-6spd, did you buy a shortblock or build it yourself? I noticed the Probe forged pistons in your list and I don't know many people running them but that's what Wheeler motorsports puts in their shortblocks so that's what I got. I guess we'll find out how they hold up huh?

Tom

94-6spd

I built this myself. I hear that the pistons hold up very well. I don't think they've been around very long so that is why they're not so popular.

TransAm12sec

Car Craft 540 Hp for 4800.

AFR 195cc Street head
ARP Head and rod bolts, main studs
Comp cams 1:5 Pro Magnum roller rockers, 294S Magnum Cam, Solid Lifters
Edelbrock Single plane Victor jr
Federal Mogul Main bearings, Piston rings, Rod bearings
High Velocity heads 2 inch spacer
Holley 750 cfm HP-series

Hey TransAm12sec, I hope that my crank snout in my 383 doesn't wobble like the one in your sig does

rustybluebird

the cam in the .gif has a journal out of place also, unless it's out of one of those strange UK cars. lol.

Must be roundy-round stuff. They're turning the wrong direction.

Tom91Bird

iTrader: (5)

That too, lol

D M N

hey how would you change the direction of the crank and would that make any diffrence

i guess they came out of a boat...

TransAm12sec

lol it does when its not attached to anything

wow seems like everyone in the club has some afr 195's. Thats a good portion of my engine build but i dont have moneys so im saving all my pennies as i too hope to be in the 500+ hp club running all motor. When you guys got the afr's did you slap em right on or did you take them somewhere to get some port work done?

Here's my combo,

AFR 195's
Comp Cams 294S solid lifter cam
Pro magnum roller rockers
6 inch Eagle ESP rods
Wiseco forged pistons (10:1)
Victor Jr intake
Demon 750
Main and head studs
'87 2 bolt 350 block
Stock steel crank

Looking to make right close to 500 hp then bolt on a NOS cheater system for a 250 shot

dans82bird

i thought you had a hopped up LG4 cartman??

dimented24x7

iTrader: (2)

looks like he wont have it for much longer... That looks like a real nice combo.

D M N

so everyone is rudding carbs no one is TPI, also does anyone know if someone has a 500+hp LT1

92 zzz28

Here's mine...Not quite done yet but will be over 500 once I get the blower. I hope it still counts with forced induction

385, forged everything, 9.3:1
AFR 190, fully ported/polished
Comp Cams blower grind
Comp Cams valvetrain
Hooker Super Comp headers
Mufflex 4" w/ Spintech muffler
Holley Stealth Ram, ported/polished
Stock rear until it blows up, 3.42s
TH-350, fully built
3000 RPM stall convertor
Griffin radiator
ATI Procharger D1-SC w/ dual intercoolers

I am in the finishing stages of putting the car back together and will be dynoing it soon after. I will post numbers, both dyno and track...

RB83L69

Yeah that kind of power is totally out of the question using TPI, without some kind of MAJOR power adder. That doesn't apply to FI in general though, it's just a feature of TPI in particular; some of the other FI systems such as the MiniRam (and I would expect the LT1, since it's all but a direct copy of the MiniRam) seem to have little trouble achieving that level of flow.

The most recent street motor I've built that was in that range was a stock-block 434 with Edelbrock Perf RPM heads, Comp XR282HR, and an Accel ProRam.

19doug90

no one answered my question.....for you guys running afr's (which seems to be all of you) are you just slapping em on out of the box or are you getting some port work done before theyre installed?

Acidtalons

exatly how streetable are those solid lift cams?

RWB____s

Well here is the setup Im starting with and the engine Dyno numbers.
355 cu in, AFR 195 CNC ported heads (right out of the box) Stock forged steel crank 1pc rear seal, Manley 6 inch rods, SRP flat top 10.3 to 1 pistons at zero deck height.

Not for long I've been wanting to put a new engine in for a couple of years now. Getting closer to the day that LG4 comes out and someone takes it away. Actually already have a guy who wants it to put in his car lol.

automec

i was just over 500(w/o nitrous) all summer (see sig.)but it is down to 0 now it will be closer to 600 with out nitrous next year and i'm building it to handle a 500 shot of NOS also

mike

19doug90

Wow you sound like youve got some money to burn. Where in ontario are you? I'm in the markham area and would love to see your car.

jcb999

see mods
made 450hp with exhaust flow peaking at 143cfm.

Now that they flow 188+ and the intakes flow 20+ cfm more.. should be 500 easy.

Riley's35089rs+

Im there....525hp....

RWB____s

I Live in Southern Ca. Bellflower Ca. to be exact. The Car is really nothing to look at, Dam ugly really. needs paint next .But it is everything i posted about it.

D M N

If your car has 500+Hp it doesnt matter what it looks like

CaptPicardsZ28

I have not had a chance to do 1/4 mile or dyno yet but I know my (machinist) mechanic (who builds engines and races cars) said I am at 500hp. I cant get anymore out of it without hurting the engine. I will at some point have a 454 built with a supercharger, forged pistons and all that pushing it way over 500hp. I may even add NOS. I am having a lot of fun building up my third gen car. I only drive it about 4k miles a year and when I do its a blast!

CaptPicardsZ28

Forgot to include my sig...Sry!

Tater13150

Those with 500hp or close to it...are the heads just right out of the box..or what kind of work are done to them!?

I guess this makes me one of the few people doing this with TPI based fuel injection.

modified GM HT383 shortblock, forged flat-top pistons and 4340 6.0 rods and 3.8" stroke crank, 11.5:1 compression
AFR 190 aluminum heads, 2.02/1.6 valves
AFR hydra-rev kit
comp-r roller lifters
comp cc306 hydraulic roller cam and true roller chain
LT1 intake, ported. 58mm throttle body
Accel gen VI DFI
msd-6al ignition system
hedman LT headers and borla catback exhaust
all ARP fasteners and external bolt-on parts are used
running through a T-56 and spec stg. III ceramic clutch, when I get around to putting this in it should be good for 525 HP. Haven't an educated guess on torque, but should be around 550ish?... With the rotating assembly I'll have plenty of room for more cam, and 200 HP shot N20.

The only thing that sucks about this is for the time being I'm stuck with a built 10-bolt. At least it's as beefy as a 10 bolt gets and I don't plan on drag-racing.

Considering I'm using an LT1 intake (which actually makes pretty decent power for a short runner intake down low) and newer DFI, I dont think I'll have much of a problem making power. Is it me or do comparable LT1 motors make slightly more HP? Comparable LT1's are making 450 HP at the wheels.

If I can't get close to that I'm gonna get pissed!

BADDEST305

just put my new engine in the car still have'nt made a pass yet. maybe next week but anyway its a 434 ci 12:1 comp, callies 4340 dragonslayer crank, lunati rods motown block, dart intake, demon 1090 carb, 2'' stahl headers, csi electric water pump. dyno'ed @ 654hp and 601 lbs torque @ 6600 rpm at the flywheel. will be finished this weekend . just have to have the exhaust put on then off to e-town or atco on wed. or thurs.

92 zzz28

First off, I am not trying to start any crap. I just want clarification. Did you mean to say 3430? I have never heard of that alloy. However, 4340 is very popular and strong...

BADDEST305

ok heres clarifaction--i should read what i type a little better. i did mean to type 4340 thanks. i will edit that post

ski_dwn_it

This combo we built is doing it in two vettes.

Everything is available to duplicate it.......awesome street motor too. Gets 22 MPG!

Pulls the two front tires right off the ground in full weight cars with AC, power seats, doors, mirrors, the whole nine yards.

EVERYTHING IS STOCK except the motors and trannies/TC.
