ive got a 91 camararo rs with the 5.0 305. my dad tells me it pretty fast for a 305 but i want more plus ide like to know about how much power im probably making now. heres all thats done, 3.73 rear,3" borla exhuast,edelbrock headers, kn filter, had the dual ram air setup but the tubes i had to throw out, short shifter,3" electric cutout, and im pretty sure someone else did some internal work cause i can outrun a mustang gt most of the time. would a power chip be wise, where should i go from here ive got 1000$ to put into the performance side of the car?

 

well...stock you are running 170hp@4000 255ft-lbs@2400,

assuming headers, exhaust, and a little better flowing intake...you're probably looking at a 20hp increase at best.

the gears will really make the car seem faster.

now if it has internal work there is NO WAY to tell what you're at. you'd probably hear a cam, although a small cam may not be noticable. or they could have put better heads on it.

it's hard to suggest mods for an engine that has mystery mods on it already.

i would suggest a mild cam, and a matched intake manifold. you could pick up something like an LT1 cam for cheap and then stick an edelbrock performer or performer RPM intake on there and make pretty good numbers. the next step would be to have a custom chip burned to match the setup. for that check out www.pcmforless.com

you could also look into a better set of heads, something like the World Products S/R Torquer 305 heads...but those are about $800 for a pair.

 

You can spend 1200 on heads, cam , intake and tuning for the 305....

or...

spend 1200 on a stock used LT1 and do a simple transplant.

Guess which one I'd choose? I definitely would not put any money into a 305.

The LT1 is a bolt in for your car. There are lots of 3rd gens running around powered by LT1s.

 

low 200s.

I would NOT sink any more money into a POS 305.

 

The guy comes in here all excited bout his car and everyone tells him his engine is a POS... I love this board LOL

not saying a dont agree lol...

 

just so yall know im quite happy with my 305, im aware of what it is so i dont need people to tell me its not the best engine ever but any engine can be fast. and for yalls info ive taken a 1993-1997 model z-28 i was barely pulling away from it my motor is by no reason slow. maybe not the fastest but not slow. but thankzz for yalls help.

 

a 1995 and up 3.8 V6 car has about the same horsepower you do. If you beat a LT1 Z the driver was either not trying, or it was a V6 car that somebody stuck Z28 badges on. You are not going to come remotely close to even keeping up with a 4th gen Z28 with your TBI 305. You are a good 80 horsepower behind, even with your mods. Over 100hp behind stock. There is just no way you could beet a car that has nearly 100 hp more than you.

Maybe your engine is not a 305? Could it be a 5.7 that has been modded with heads and cam? Does it look like it is stock? Is the harmonic balancer a 5.0 or 5.7 piece? are the heads aluminum?

If you are in fact beating LT1 cars there is definitly not a stock TBI305 under your hood. Do some more research, or go to the track and see what it actually runs. LT1 cars run 14.1 stock. Then you can compare.

 

ya ide like to go to the track. and someone told me they think ive got a 350 under there cause of the power it makes, but im pretty sure its a 305.

 

Agreed, go to the track and post results, then we can at least make an educated guess on what it has done to the motor if anything. Everyone's definition of "fast" is different. Before I got this car, I thought my mom's car was pretty dang quick (new 3.5L Altima). Now whenever I drive it I get bored cuz it seems so slow.

 

i had a 90 firebird w/ 305 TBI. i had 373's, lt1 cam, edelbrock intake manifold, a cutout on it, and a vaccume fuel pressure regulator. i probably had maybe 230 horses after that. i ran a 14.9 @ 92 at the track, and that isnt even close to lt1 times or power.

 

my friend has a 2001 mustang with the v6 where should i run in a race with it?i think its got 190 hp stock or 220 not sure wich.
if i was to race it yall think ide win?

not considering anything discussed so far.

 

A 305 may not be the hottest perfroming thing on the road, but they are pretty torquey to drive around town, and a VERY reliable. From 0-40, these cars are not bad at all. They just run out of steam in higher rpm's. (in stock form) The only mods I have done to my LO3 are a Dynomax catback, and a K&N. I figure it would probably be a mid 16 second car, am I wrong??

 

I beat a 305 camaro with my bolt on 99 neon.

 

i agree with everyone else when i say u are either full of poop, or u definately dont have a 305. i knew a guy with a 305 with heads cam and nitrous and i still beat him in my old 93 camaro with gears..... i am giving u the benefit of the doubt and saying u dont have a 305!

 

in a 0-70 race how many car lengths ahead or behind should i be in a race with an 01 mustang v-6?

if this is a regular 305?
