what should i do to mod my 91' camaro that has a v6




put a v8

put headers on it


get a cam


or other, what do you guys think

 

I personally think you should junk the 3.1 or 2.8 in favor of a 350. Main reason is that a v6 even modded will have a hard time pushing a 3500 pound car. You can also find more parts for a 350 and you would have a good foundation to start modding your car. To do this swap v6 to v8 i would start saving money and invest in a junker camaro that runs strong. Then just swap parts over and possibly rebuild the engine if you have the money. In the mean time you can invest in suspension etc if you want to turn some wrenches.

 

yea, i was leaning twords that but thanks i just needed to hear it from some one else. does anyone have any ideas of what kind of 350 i should get because i have a limited budget. because i really dont have the time to rebuild one i just want one i can drop in and gradually mod it from there.

 

My car use to have a 3.1 in it and I recently swaped it with a rebuilt 350 30 over to make it a 355 and put tbi on it. Anyway the 350 you want has to have low miles and you most likely want a 4 bolt main. You can use a 350 with a 2 bolt main but it limits you to about 600 horsepower. The main thing you want is a STRONG BOTTOM END. I can also tell you that you will need a ton of parts to swap from a 6 to an 8. Engine, Trans, Wiring harness (if fuel injected) Motor mounts, Radiator hoses, Ac lines, springs etc. The point im getting at is you will need a junker 3rd gen camaro. I dont no which years had 350s and which ones are better than others. I belive all the camaro 350s were tpi (tuned port injection) i know irocs have them. That will be the cheapest way to put a v8 into your car. If you want tbi you could find a 305 junker camaro and swap that in or find the tbi and wiring and put it on your 350 and reprogram the ecm but i wouden't bother with the 305's.

 

but about how much would it cost to get a 350 with a 4 bolt main new, i dont need a really good 350 just a little better than basic but i want it new

 

Sell your current ride, and purchase a RS w/ a 305 TBI in it. Like someone said, the stuff necessary for a swap like that is an endless list.

I'm in the process of switching my 305 TBI for a 350 TBI and it's very straight forward. If you just want a 350 block, and you're not worried about the performance, and just want new:

This is where I got mine, but it was still a good deal for all the stuff I got added to it. If you were just to take out the stock 305 (LO3) and put in a 350 (LO5), the only thing that needs changed are:

bigger injectors, esc module, knock sensor and a 350 PROM

all in all, those are not more than $300 total.

I hope this helps.

You might be better off buying a car with a 350 in it already. I'm not sure how much you have invested in your car right now, but I would look for a car with a 350.

 

have you thought about putting a turbo on your v6?

 

yea. i just bought my car so i dont want to sell it, but if i do get a new 350 thats stock or a little better, i can still put mods and stuff to make it fast right?

 

350's and 305's are very easy to mod, but for what you're going to pay to swap a 6 to an 8, I personally would just find a V8 camaro.

If you want to know what a V6 Camaro is capable of, you need to go to the V6 page. I don't know what's available for them, nor how fast someone has gotten one. If you're strictly interested in yanking the motor and putting in a V8, then the engine swap board or the V6 board would be a better place to go.

Sorry I can't be of anymore help.

 

wrong forum

 

Thought the sudden appearance of an active thread seemed a little odd.. 10 replies and I hadn't even noticed it? Impossible!!

 

Sell your V6 equipped car and buy an IROC or Z28 with a TPI 350 already in it. Unless you have good contacts, it'll cost you quite a bit to do the swap. You'll be able to make maore power with the V8. But when you're busting your knuckles changing the sparkplugs, don't say I didn't warn ya

 

kkep the v6 stock for awhile, drive it, then sell it for the z28 or iroc. its the cheapest and easiest way to go.

 

I just did the v6 to v8 swap and unless you REALLY want to put a v8 in your current car its ALOT easier to go buy a v8 car and like said before you can easily spend the same money on the swap then you would if you bought a v8 car. I think i spent like $150 just on stupid little crap you dont think about untill your deep into the swap.

 

i dont understand what is so hard or expensive about the v6-v8 swap unless you were paying a shop to do it and in that case yeah its rediculous to do ...but to do it yourself its not that hard as long as you have patience ...and as far as expensive if youve got the engine your not looking at that much more to finish it really just pullleys and tranny and motor mounts and other misc. stuff my me and my brother just did this to his car and with the engine and transmission and everything to complete it he has maybe 2800 in it and thats running a very healthy 350 thats far from stock
so dont listen to these people that keep saying sell it and buy a v8 car thats rediculous and as you said you just bought the car and thats what you want other wise you wouldnt have bought it so save your money drive it with the v6 when you get all the parts tear it down and put it back on the road and have fun with it

 

thanks, that sounds like a good plan

 

Yeah, don't listen to br()bert... it's not like he's JUST DONE THIS HIMSELF or anything.

 

Oh, and as far as the 2bolt limiting you to 'only' 600hp... there are EXTREMELY few real 600hp 350 sbc's you'll come across. Seems everyone and their neighbor's cousin's uncle's friend's buddy from 'nam has a 4 bolt 3/4 cam race 350, that runs 11's.

Dropping $2k into a 350 (including machine work) should net you a solid 330-380rwhp, depending on a number of factors.

 

??? you mean me ???
i just got done with this on my brothers car too man not saying not to listen to any body

 

It's definately easier - and probably cheaper - to just buy a V8 car.

1. Front springs need to be changed

2. Radiator needs to be changed

3. A/C will have to be re-routed (or removed)

4. Obviously, the v8 motor is needed

5. V6 trans won't bolt up to a V8, you'll need a new trans

6. To keep fuel injection, you'll need the whole TPI system (intake, wiring harness, computers, injectors)

7. You'll need to upgrade the in-tank fuel pump to a V8 pump, V8 tpi pumps flow more than a V6 mpfi pump

8. All accessory brackets would be needed (power steering, alternator, etc)

9. Exhaust is needed, but could easily find headers instead of goofing with the stock manifolds. If you go with stock manifolds, you'll need the stock y-pipe

The exhaust "after the y-pipe", including the catalytic convertor, intermediate pipe, muffler, and tailpipes is the same for a v8- unless you've got the stock small V6 exhaust, but at least it's one expense you could deal with later.

The rear axle and driveshaft are the same strength as the v8 ones. The rest of the frame is also as strong as a v8 car's is.

It's more work than "just dropping in an engine". Of course you could throw all the fuel injection stuff out and go with a carburetor- it's not the way I'd do it, but you'd have to keep in mind the emissions laws in your state.

 

Tom is exactly right, except i didnt change my springs and besides it lowering a half and inch then before i have no problems BUT my springs are not the original ones from 85!

And you dont have to remove or change the fuel pump.(IF YOU GO FROM FI TO CARB) YOu need a mallory 4309 adjustable fuel pressure regulator. It drops the pressure down for a carb and returns all the extra fuel back to the tank.

The hardest part was the mounts and it seemed like the little stuff is what kills ya.

It comes down to do you really like your car or not. Would i do the swap again ? Probably not! Id just buy a v8 car and upgrade the rear gears (if it came with crappy 273's)

 

Sorry i cant edit my posts, im still on probation


Also the only reason i went v8 is i got a good deal on the motor with the trans. I was going to go with a 3.4. The 3.4 offered a little more power then my pos 2.8 and is a hell of alot easier to put in then the v8. Just something to think about...

 

It all comes down to what you can afford, and what your patience level is. (Oh, and how insane you are, too.) If you buy the parts you need a bit at a time, you could do a decent V8 swap. Procure your engine, maybe do some out-of-car maintenance on it, get the transmission, do lotsa research as to what it entails, and when all your ducks are in a row, you can slam your V8 into your car and drive away happy!

 

LT1, 4L60, wiring, computer you can pick them up for around 1200-1700 bucks. This is the best V8 swap you can do if on a limited budget. Unless you can get an LS1 to swap in.
