still dont know???
its a 4.3

ill know in 2 days if i get those pistons for it or not

but im doing somewhat of a hybrid motor if u could call it that

early non vortec block ( no balance shaft)
with vortec heads and pistons

for an intake i am either going to fab up a sheet metal manifold, or use an edelbrock intake

ive alread got the 4.3 shortblock and i have a set of sbc h-beam rods ill be using
if all goes well ill score those 4.3 vortec pistons if not ill buy new speed pro forgings which can be had for about 32$'s each

ive also located a 2004r out of a montecarlo ss that will be going behind this motor and of course it will be turbo charged
im going twin turbo starting witht he pair of t3 50trims i got then i will step it upto twin t3/t4 hybrids
all of this will be done over the winter once race season is over

ontop of that my entire current setup is for sale,dont ask cause i will not sell the turbo headers seperatly
1k takes
the motor complete
the entire turbo setup including the intercoler and all plumbing including the crossover pipe to return it to a single turbo configuration( minus the turbochargers and wastegates)
the harness for the megasquirt but no megasquirt itself
but u will get all the tune files so u can buy an ms plug it in and run it
AND THIS IS IMPORTANT
i will not ship
local only and u must come in person to look at and pick up everything

 

I'm going to have one of those engines too...here in a couple months. Its not going in my 3rd Gen though.
You're leaving the 60* community and moving to "The Dark Side" (The dreaded 90*)?

Why are you ditching your setup so soon? You haven't even touched what could be done.

Too much pressure with me and FF building hybrid set-ups? Its cool, I understand...just more 60* records for us

No but its good to see someone finally doing a 4.3 swap.

 

It was a matter of time till someone decided to turbo a 4.3. Let's see if you have more luck with this engine.

 

lmao naw i want to go into the 9's not gonna happen with a 60* 2.8/3.1/3.4 hybryid or not

ive been looking for quite some time for a new setup, ive been looking at some buick stuff gm stuff and yeah i hate to admit it i even took a serious look at some 4cyl stuff

lil while back i came across a car with a 4.3 and a single turbo (75mm) well into the 9's, all forged bottom end and what not, but factory heads etc. it actually wont cost me anymore to build then the 3.1 did specially since i already have alot of parts needed for it

the crankshaft is going to be my weak spot and the one place im going to have to spend some cash


oh dont you worry theres 2-3 months more for the tracks around here to be open i will be posting an 11 second slip before i leave the 60* stuff behind
i am the current 60* fbody record holder and dont intend on leaving until i set the bar very high for hybrid guys


btw incase u dont know i just recently went twin turbo on my car

 

your missing 2 cylinders....


Good luck with the build, should be a very quick combo. If your going to build a V6, thats the best one i can think of

 

We will see about that. FF has a better chance than me...as mine is going to be a summer DD.

 

well i could think of one better, grand national engine but that would be to easy

trust me noone will ever hit 9,s in an fbody with a 60* motor atleast not unless u have a really really huge wallet. it takes around 750 hp to go that fast. depending on other factors as well


the only 60* motor that may stand a chance would probably be that 3.6 di motor but that all depends on how well the aftermarket picks up on them when the new camaro comes out

 

lemme fix this forged rods and pistons stock crank and block but the guy is at his limit but he said it will live as long as the rpms are kept down
hes doing this with a stock 2 bolt block and crank

though u can get 4 bolt main billet main caps

so looks liek this is going to be cheaper then i though

jy 4.3 100 bucks
vortec heads 100 bucks
rods = free
pistions are right now 12$'s for the set
if not speed pro forgings = 36.95 each

and if its anything liek my 3.1 the entire gasket set + bearings freeze plugs and rings will be liek 250 bucks

 

Um, the 60* has already gone 6's

 

umm and how much money did that cost? that was a full blown race car with a sponsored team.theres not a single person on any of these boards that could duplicate that


enough time and money and one of us will see 10's on a 60* but thats it
i will go into the 11's before my 4.3 is done though

 

Tim King has 3 kids and built his 8 sec Firebird in his garage. It can be done, there's just not a lot of people willing to do so.

I hear you about time, I has none.

 

that car was still built in a shop, that guys had more in his 2 turbos and the chassis on that car then most of us will spend on a new car lmao

u knwo his car is for sale right, i saw it up on racingjunk or someplace else

 

No offense...but you have no idea how much time/money I am willing to put into my car/engine.
I have to say that it is kinda sad that you are quitting on the 60*...you've made all these claims, and are just going to swap to a larger motor because its "easier". If it were anyone else on here It wouldn't matter as much...but you've taken the 60* to far just to give up on it IMHO.

But hey...to each his own.

 

i was referiing to the 6 second car ff was refering to
if i was quiting id be parking the car now and saying eff it i have full intentions of finishing out this race season with the 3.1
u guys will see an 11 second pass out of this car before the season is over

this has been a long time coming, even before i installed this 3.1 in the car i knew i was going to a different motor

that and i hurt the car last time out that 13.00 run hurt the transmission yet again its developed some decent flare on the 2-3 shift im getting really tierd of throwing transmissions at this thing ever 2 months

tci racing rebuild kits arent exactly cheap either 350 bucks a pop everytime i burn up a 700r4 and thats only if i dont hurt any hardparts.
im down to my last good transmission

ive spent more on transmissions and rebuilds then i have the rest of the car

yes i could swap in the th350 i have but why when i would have to spend 1k on a converter

by all rights i should forget about the 4.3 and drop in one of the sbc;s i have at the shop
either the ls1 or the full forged 355, but thats not gonna happen

who knows if noone bites on the motor and turbo setup it could very well make its way into somethign else

i.e a lil dragster

i do work in a chassis shop ya know

i think a 3.1 tt powered dragster would be kind of neat actually, we have built a few of them already for guys running v6 vw motors and stuff and there dirt cheap to build

 

Oh...ok. I misunderstood that. I also forgot about your tranny issues...At least its still a 3rd gen. Either way, this is going to be an interesting year ahead of us

 

these motors were not meant for drag racing they were made for cruising. You did squeeze alot out of yours tho man. Ide love to buy your setup but first i wouldent know how to put it in and 2nd i wouldent have the time to figure it all out and buy the toold needed but I do hope someone jumps on that deal good luck on the new 4.3.

 

4.3 hmmmmm will it fit behind the axle line like the 2.8? I may have found my C prep engine (NA of course but still lots of power)

 

actually im not sure it will bolt in the same as any sbc but i dont know if the mounting pads are moved foward on the block to move the motor backwards to make up for the shorter lenght.

gonan be time to break out a tape measure and check

i would imagine it would not sit as far foward as a 305/350 being its a 350 with 2 cyls choped off it

hmm would the extra power be worth the extra wieght for you? though 300 hp and tons of tq , without the need to rev high could be a big advantage i quess

 

I'm looking for a big power increase since I'm running against V8 3rd gens and LS powered 4th gens. I think I can absorb a small weight penalty as long as the power increase puts me in contention. I was thinking about using the S-10 adapter mounts since they are slotted and already move the engine back. Even if the crank ends up just ahead of the X-member it will be better than the V8 cars.

My plan is for 300+HP at the ground N/A carburated. And here's what I think it will take: 10.5:1, big cam, good heads (Probably ported Vortec) S-10 headers (modified) and more or less open exhaust from there. The 3.4 could get there but I think it would be highly stressed and less reliable as a result.

 

300 hp should be a walk in the park

an older 4.3 block with vortec heads will yield higher compression then going with a full vortec motor, coupoled with a nice cam will deff get that thing moving

check out edelbrock's power packages they have a nice cam and intake setup for the 4.3 and i do belive it puts those motors up over 300 hp

 

ditch the vortec pistons and run sbc dome pistons thatll get the compesion up and the ho heads i believe flow more open than the vortec heads do the ho heads are found on the 80- early 90's 4.3

 

for him that will be fine, but im going turbo so i have to keep compression low
im prolly gonna skip over swaping to the vortec pistions and just go buy some forged d dish pistions for it since they are dirt cheap

 

Well hell I think I am losing faith in the world now. We will miss your 60 degree build. Good luck on the 4.3L.

 

im not exactly done with the 3.1 ye,im going to swap out the massive cam i have now for something a lil smaller to bring the power band down about 500-800 rpms. and then im going to crank the boost on the twin turbo setup and see what it runs.
ill run the 3.1 for a lil bit in the begining of the season before going to the 4.3,and ultimatly going to a 355 sbc with a turbo for the follwing season.

since im going to the sb the follwing year i have decided not to do anything special with the 4.3, ported heads and a cam is about it. theres guys on the turbo forums taking stock shortblock 4.3's with ported heads to the 600-650 hp range without trying to hard at all, thats more then enough to go into the 9's to get my nhra comp liscence

 

i should also add i may be looking to pick up a mini dragster chassi like they use for the vw v6 and import 4/6 inline motors for the 3.1 once it comes out of the camaro

 

project89, the 4.3 is drop in fit. use v-8 mounts in the v-6 location (IIRC). I ran one in my 84 bird , with a 5 spd, Edelbrock van headders (slightly moded) and a v-8 radiator (req'd v-6 monte carlo hoses top and bottom,trimmed, to connect.

 

yeah i knew it was a drop in, i was just unsure of which mounting location id have to use

the 3.1/sb rad is the same in relation to hose size and outlet inlet loacation. i do belive the v8 unit is thicker though

u have any pictures of it in ur car, id like to see how much room is infront of the motor

 

I'm very interested to see how this turns out.

 

project89, sorry no pix. As far as front space goes, I had a mechanical fan and radiator shroud which still left plenty of working room. Switch to an electric fan and you'll be able to stand (almost) in the space between the radiator and the motor. Should be more than enough room to answer the "where do I put my turbo(s)" question. Iclr routing gets easier too.

 

actually my plan is to run a sbc low mount alternator kit with electric water pump on this,and wil convert to a manual s10 steering box.

i was just curious as to how far the 4.3 is setback compared tot he 2.8/3.1

 

I work on Sy/Ty's all the time.. builds and upgrades.

The SBC rod isn't going to fit first off. The 2.10 Journal of the small block rod is too small for the 4.3L Journal.

Anyway.. Keeping a 4.3L bottom end together is a challange. Just a bit of detoanation and your wiping the middle main's out of it. No headgaskets are going to blow... Just wipes out your bearings and it's rebuild time.
To make dependable 600hp is going to cost a fortune. I know the Camaro isn't a 4000lb Typhoon and your only running 2wd but they are not a SBC even though the shair some qualitys.
Save your self some greef and do the small block. It'll make more power easier and be more dependable on the bearings.
Sorry to be the bear of bad news but I think your wasting time and money.
~Scott.

The GN engine isn't a simple fit but it does work

 

yeah i found out about the sbc to 4.3 rods, alot of ppl have told me the 4.3 is going to come apart, but ive seen a few builds if u can even call them that lol with guys making 600+

why does detonation eat the middle mains in a 4.3?

 

Come over to www.syty.net and post a few questions. You get some good information from all us there that build them all the time.

They are great guys... Good info.. and a chat room
~Scott

 

You should section an HSR and a set of cheap aluminum heads to fit it, it has been done....

 

i know its been done but its not in the budget, the hsr comes out really nice when done for the 4.3 but im going to build my own manifold hogans style

 

Keep us posted, and with all the pics possible. http://www.youtube.com/watch?v=KkglxJH6jGE <---1204hp 4.3 by Nelson Racing Engines.

 

ive seen that video that motor is a screamer dam near 8,000 rpms

 

That must have coast a fortune, that motor looks completely custom, and who knows what its got for internals. Looking forward to see what you do with one.

 

my final descision on this is to do the swap.
ive looked over a few ppls builds on the turbo forums and these guys are getting stock 4.3's way up there in hp numbers with blow threw carb setups and e85

im going to do this on a budget and a half since im only going to toss the motor a year later anyway

so heres what ive decided
im going to use the non vortec shortblock with stock crank and recon the rods, arp main studs and rod bolts
new bearings, oil pump etc
the pistions i will swap out the cast pistions for some low compression hyperectics
reground cam from delta to round out the short block

on the top end im going to use a set of self ported vortecs and build a custom manifold with 2 injectors per cyl so i can make use of the staged injection on my megasquirt for ease of tunning for daily driving.(first injector set will be a set of 24# or 36.6 pound injectors, with the second set being 42#'ers)

ill back the motor with a 2004r trans out of a montecarlo ss with a stage right transbrake,and my curerent tci converter 4.5k stall which i will send out and have it tightened up a lil bit

for the headers im not doing anything special just heavey gauge mild steel twin turbo headers prolly log style.at first i will be using the twin t3 60 trims i put on the 3.1 and eventually swaping to the t3/t4 hybrids

i managed to pick up an air to water inntercooler unit for 37 bucks that i will use on this build.

ima drop it in the car with a hope and a prayer it stays together lmao

 

to bad i cant shoehorn this into the car, its been sitting around the shop for a few years now







incase ur wondering what motor that is its a 472ci blown alky hemi uses a whipple screw blower and makes around 3,000 hp

 

http://uk.youtube.com/watch?v=6JKJXWO6yF8

 

are you SURE that hemi won't fit? lol

good luck with the 4.3, amazing amount of torque in those things. my sister's S10 has one. that being said they're a little cumbersome. I mean that as they don't have the initial reflexes of a smaller engine. if your thinking about your launch time it might be something to think about, but I'm sure once you get a few 100 more horses out of it that won't be an issue.

 

lol even if the hemi did fit, the car would need a full tube chassi and lots of bracing lol.

lmao the whipple screw blower that goes on that motor is around the size of a 60* v6 block


the motors outdated and wouldnt be competitive now in the tad ranks,hell its hard to be competitive with any blown alky car now with the nitro injected cars.
we have enough parts to assemble prolly 3 of those motors sitting in the trailer from when when sold the dragster,one day well actually build something to put it in

hers a pic of the old car its not real recent but the only one i have on the pc


the 4.3 should have no problem moving my car off the line lol ported heads.cam and a decent amount of boost to motivate it shoudl make for a really fun ride
