hello to all just hav a quick question im finna buy this 91 camaro rs 2morrow its a 305tbi but the guy put an edelbrock intake and a holley carb i wuz just wondering can i take the holley carb off and convert that 2 an holley stelth cam is it possible or is it just a waste of money??????????????

 

I assume you mean stealth ram? If your after an MPFI setup, a 90-92 TPI setup would work well with the stock 305, and would be cheaper overall.

 

hey ur rite it is called a holley stelth ram what all do i need to do to set it up is it like plug and play or what the car is carbed with an holley car rite now and how much do u think it would cost to purchase and to install it?

 

Itll be around $2k or so for the whole system. The intake is something like $300 by itself if I recall.

If your keeping the stock 305, this will be WAY overkill. The better bet is to get a stock TPI setup. The earlier MAF setups (86-89) will require less attention and probably will work right off the bat without much tuning. The older MAF setup is crap in my opinion, but it will probably work better then the carb and meet emissions if your subject to it. The later speed density setups are better, but will require more tuning to get it to run nice.

 

Stock tpi setup? Bah

Get the stealthram, repin the harness to '730 specs (You'll find a post by me), replace the pump in the tank.

The stealthram out of the box will be fine for the 305. It's kinda the middleroad between TPI and miniram / lt1.

Run the stealthram until your 305 explodes, then get a performance oriented longblock.

Anethes makes some good points. Stealthram is around $600 for intake, fuel rails, and assorted adapters and fittings needed. Used would be a bit cheaper. Its rather easy, and no need to swap over to another computer. Beat on the engine while you save up for a performance one.

 

man i really apperiate all the points that u guys hav made but i got the car a couple of dayz ago and i think ima keep the setup thats already on it i payed 3800 for it look at all the recipts that the guy gave me and he put over 8500 in the car so i think ima ride it till the engine doesn go no more then ill upgrade to a ls1

 

this is all the car has i no a lil about cars and in the learnin process so if u guys can let me no what sum of these things are:

Sounds good. Toss a HSR on it and let us know how it worked. Try to get a few 1/4 passes in before so you can get a good idea of the before and after.

thanx man so what is an hsr??????????

 

I'll buy that nitrous kit off you

 

HSR =holley stealth ram

 

wow how come i new that just wuznt thinkin thanx

 

Too bad it's a 305, that is a great deal for all those aftermarket parts though, especially if the body is in good shape. I just can't understand putting ALL those parts without opting for some displacement first. As far as 305's go, that should run plenty well.

I would love to have that rear end setup... I am currently looking for one just like that...you won't be able to appreciate though rear disc brakes and rear until you have driven a stock drum rear end, with no posi and 2.73 gears.

 

RE :hey man thanx for your input the 305 is a good motor though its pushing out 300 hp the only thing i dont like about the car is that it has a th350 and that will b change over to a 700r4 as soon as i get a $1000 but what do u mean by displacement what is that im kinda new to the car stuff just learnin as i go still tryin to figure out some stuff on the car

I am assuming the 300hp with that carb and setup is inlcuding the nitrous. Otherwise 300 sounds a bit high, it is possible but not very likely.

Anyways, displacement means the volume of air (not including turbos or superchargers) that a motor can hold. 305 cubic inches is the displacement(5.0 Liters). A 350 would be from 340-355 cubic inches (5.7 Liters). With the older intakes TBI (throttle body injection) and TPI (tuned port injection) is becomes difficult to try and make horsepower past a certain level with a 305. Not saying you can't make plenty of power with a 305, but the extra displacement is like a shortcut in a lot of cases.

If the carb runs well and doesn't get too bad of mileage, I would keep it carbuerated. Switching to TBI/TPI/MPFI/EFI would require a new ECM(computer), lots of tuning, probably a new fuel pump, and larger injectors than stock to make any real power.

Its a lot of work, time will be more important than money.(Just because something is affordable doesn't make it an easy out)
If you have the time, use the boards to learn and carefully select parts. You can get just as much power out of a TBI unit as you can an expensive holley ram intake, but it all takes time and knowledge.

P.S. 700r4 has overdrive, overdrive = better gas mileage
But, most 700r4's have a lot of issues and stock ones have a lot of flaws, if you go this route has it done PROFESSIONALLY@

 

Hey Maverick,
I am new to working on cars too, although I am having a blast learning.

Can you elaborate on this statement you made...

"But, most 700r4's have a lot of issues and stock ones have a lot of flaws, if you go this route has it done PROFESSIONALLY@"

I have a 700r4. Is there a better type of tranny for a 350 engine? Just curious

 

better?
Well I will say this.
The TH350/400 are great trannies. Tough and can handle alot. But they are only 3 speeds, so highway mileage is out the window.

The 700R/4L60 CAN BE a Great tranny. IF DONE RIGHT. The pre 87 have a good input shaft, but the post 87's are hardened from the factory (or so I have been told by many people)

The 4L60E is just another updated 700R. All computerized. Yes they are basically the same, just radically differently controlled. They are pure electronic control.

I have driven on 350's and two 700R's (really the same trans just prior and after rebuild). The 350 was worn out and still lasted several years. The first (or I should say before rebuild) I could tell was not like the 350. It shifted different, the power holding compasity was different, but it kept the milage high as it cruised at under 2K @ 65 MPH.
After the $650 rebuild and new higher stall 'verter, it was a different beast... in low gears it had no trouble moving the vehicle at all. I felt it would handle the 383 with ease, where as before it was very questionable.

Long story short, 383 with old trans equalled high revs and not much movement.
After rebuild, it equalled a squating rear end and squelling tires...

 

Done some of that in my day


Sounds like a fun setup to play with. If it runs decent, Why change it?
Blow it up then worry about what to do next.

 

Hey V6,
What all is involved in the rebuild you mentioned. I am probably going to need to get mine done eventually.

Thanks
