I was thinking of getting a Bird with a nice body and a blowen 2.8/3.1 V-6 then swapping in the 4.3L V-6 with a 5spd on and auto either way.

just to have a little different cheaply built car that ain't so bad on fuel but still has some power.

i was thinking like a 4.3 TBI with some 3.73 gear's....

 

Its been discussed before. You would have to swap as much parts as you would if you were to drop a v8 in.

You would be better off finding a blown 305 RS and dropping a 4.3 infront of that trans. Then quite possibly the ecm would still work on that engine, just modify the prom for it.

 

Yep. 4.3 is just a 350 minus the #3 and #6 cylinders. Same work as a 350 to get it in there, just smaller.

 

i agree with dale...find a blown v8 bird and drop the 4.3 in it...no mounts to change and the tranny should bolt right up...

 

ok well either way ........
I'd still like to do the 4.3l V-6 witch i think they should have done factory as it would have been a better v-6 then the 2.8's in da maro's and da 3.1
s in da bird's.

I'll more then likely never!! buy another 350 F-body again.....

there either poorly maintained and beaten or there way over priced.......

I'm thinking 3 T/A's one with a 406MPI one with a 350TPI and one with a 4.3TBI.....

As i'm starting to get tired of Third gen's..........

i really really want a 67-69 with the 400poncho and 4spd...
slightly tweaked of course

 

i ain't worried about the cost of part's as i get awsome deal's

I was just thinking da little wusser v-6 car's i can get really cheap there are in Nice Nice shape....

 

If you're willing to replace the engine, transmission, computer, wiring harness, etc etc etc... should be no problem with the setup. But as noted, a 305 TBI car would be a better platform to start with..

 

Nothing to do with Camaros vs Firebirds... 82-89 V6s were 2.8s in both, 90-92 were 3.1s in both. No difference in the motors camaro vs firebird except 85-89 Camaro versions came with the superior dual-filter TPI air induction setup.

 

Well how cheap would an LO-3 car be?? i was thinking like $250-$750 car.......

 

Depends on your area... there's a nice 2.8/A4 for sale, for $500 here. Runs good, too. : /

 

There is a guy here with a nice 92 RS V-6 5spd.....for $750

 

So what your saying is the 4.3 is going to spin a rod bearing and blow up in 35,000 miles any way so why not just get the 350anyway?......

 

Only reason for any motor to spin a rod bearing in 35k miles is poor workmanship or defective parts.. has absolutely nothing to do with the motor, and especially not a 350, otherwise my 305 with the same crank, rods, and bearings would have gone up in smoke 265k miles ago.

And I picked up my 305 TBI car for 800 with next-to-nothing wrong with it, so it all depends on your area and your connections.

 

to make your swap easier , you'll find many parts out of G-body Monte carlos and El Caminos that came with a 4.3 liter engine. Carb, ecm, and correct motor mounts.

 

Aint nothing wrong w/being different, just make dsure you follow thru

having ecm & matching haness doesn't hurt either

 

stock 4.3s aren't all that great either. if you're going to mod one, it might make for a quick car. my dad's s-10 w/ a vortech 4.3 is slower than my car, modded 3.1. the best 1/8 mile he's gotten with 1.6 roller tipped rockers and 3.73 rear gears is a 10.19, i think at like 70 mph. the motor has potential but nearly stock still doesn't do much.

 

At least theres performance parts out there for the 4.3. But it is alot of work just to keep a 6.

 

stock 4.3s from trucks aren't going to have a high performance cam in themeither. Look at the 2030 cam for teh 60* mills, you'll see 2 offered, one for low/mid range (good blazer cam) and the other one for upper band power (the f-body).

 

It don't matter who built it or how many miles were or are on it when I start driving it they last me only 35k then the throw #7 ROD some time's yea get lucky and it only spin's a bearing....

 

the L-98 in my 91 GTA only had 75,000 on it when it spun a rod bearing only 23,800 miles of them was me driving it.......

the 350TBI aka LO-5 had 190K on it when it died of a spun bearing but i only put 27,070 miles on it.....

I had an 81 blazer with 350 2BBL threw #7 rod threw the side in 12,957 miles of me driving it..... the second 350 in it spun 3 rod bearing's....i only put 5,500 miles on that engine... so i junked the truck it had 97,9??miles on it..

Then My 66 chevy c-30 well let's just say they quit warrentying the engine's after 2 year's...

But it popped 4 block's in 2 year's....

now the 66 Chevy C-30 has had a 406 init for the last 5year's still running strong......

the 91 GTA will soon be rolling again with a nice EFIed 406sbc...

the 87 GTA's L-98 seem's to be hanging in there with 120,000 on it....... so i'm hoping it last's...

i wasn't going for a fast v-6 i was going for a durable more stout V-6.. then throwing a set of 3.73's behind it and let it be....

 

The 4.3TBI i was looking at has the 4.3 turbo's cam in it.
fresh rebuild with only 24,000miles on it.

Dude only want's $1,500 for the engine.I think I can get it for $1,200Tho But then again i might get it free
The car i found was a 92 RS v-6 with a 5spd for $750.

so for $2,300 i'd have a nice daily beater that is ok power with decent mpg, and look's very awsome.

Just woundering how I could go wrong on the deal??

then down the road if i wanted to drop a 406 in it would just be a bolt in and go type deal....

But if you Don't think it's worth it I'll just pass on the Car and Engine and wait for somthing btter to come along Like a mint 67-69 that just need's a drive line

 

Kinda sounds like you should get the engine, but hold out on a car until you find one for cheap with a blown V8, then do the swap.

 

If the paint and body are clean, a 92 RS rolling chassis is definitely worth 750.. or more. If it runs, however, you might want to consider driving it for a week or so and seeing how you like it before you go pulling the motor.

 

Well it is a runner and driver. it run's and soubnd's great i look's Like a Brand new Paint job or atleast it was well cared for.

Inside and out are like brand new i swear it was just Built .....

I was just thinking " Little V-6 Fairly heavy car "

So i was just thinking for cheap i could have a Nice car with a Decent sized V-6....
