305 T5 owners. Whats it like out on them streets???

There is really not much to race around me, mostly stock cars, daily drivers, lots of trucks, never see any rice and other 2nd 3rg 4th gens are allways going the wrong way.

Ive ate my fare share of lexus,bmw and other casrs that should beat me but dont. Most give up once I rip second gear. Only sporting a 2.8 right now. I can out reve just about anything you find in daily traffic.

Im thinking a 305 will just make it easier but with alot more tire smoke.

I'll let you know when mine is done.

get a 350??? i love my 305 but if ur gonna put an engine in put a 350 i think ud be much happier

I have yet to have a race with my car here. Most of the time it is kids driving around going the other way, and I think the way my car sounds, they aren't that quick to race. Not saying that is sounds like it is all that, it is just different and loud. I think it will be better than your 2.6. Enjoy.

My 305 with the T-5 is pretty quick thru the first two gears. yes that doesn't sound like alot but I am above 60 MPH by then and most poeple will quit by then. 305's struggle at highway speeds BIG TIME. I recently drove a 95' LT1 6 speed and honestly my can (with its current mods) felt faster thru the first two gears. The LT1 shined when I could rev it to 6 grand in third gear, something a 305 will never do effectivly. Oh and for the record I can beat my roomates 335 HP 2002 SS 6spd to 30 mph with my 305, (because of the low power band) but after that, night night sucky 305 and watch him disgustingly fly past me so fast you can hardly follow him with your eyes. So all in all, a modded 305 with a T-5 can race poeple to about 40mph and look good, however, if they keep up the fight they will most likey beat you.

its a good running 305 and its free.

irocbarry

mine runs pretty fast through third and into fourth butanything after 80 or so im toast

jocww

my 84 z ho is pretty fast i can smoke most cars and can spin my tires beging in 3rd first and second i have to feather it if im racing really hard but its fun to make smokies:hail: :hail:

Their ain't no way in hell a 305 has a better powerband or more torque than a 2002 Ls1. Whats happening is your roommate has so much power its hard to keep it from spinning in 1st and 2nd, so he either has to ***** foot it or turn on the traction control and wait for the bog. I've raced Ls1's in my Grand prix, and TRUST ME, they are no dogs in 1st/2nd gear, thats where they are strong in fact.

90Iroc-Zee

I don't know, the LS1s seem okay but I only raced Autos so I couldn't tell ya. I can imagine a 6 speed spinning out alot, tho I can get most auto ls1s off the line and going into 2nd. by the way its not the 305s fault in 3rd gear...it would be the great TPIs fault...:hail:

if the engine is for free why not build it and sell it...thats what i would do, i wouldnt swap any engine but a 350, but i dont have the $$$ so im going to mod the 305 till its little heart (crank) cracks

Actually dude the LS1's shine above 3500 RPM. Yes they have low end but it is not all that. It is their upper RPM power that is just incredible. You don't get nailed in your seat until you see 3000 + RPM, and beyond then the power is rediculus. Lt1's have a little bit lower power band than the LS1's that get them off the line quick. He has his traction control off and he is on it gun ho. he gets a nice scratch into second but nothing wild and barely a chirp into third. My LO3 as modded now makes probably around 300 Lb Ft. I hope that with my mods I have gained 45 Lb Ft from the factory 255. However I see this torque at like 2000 RPM where he sees his 345 at 4000 RPM. So to about 30 mph (half way thru first gear for him and into second for me) the cars feel pretty identicle. And I am not talking about a stock 305, I am talking about one with similar mods to what i have.

since the engines free, you should drop in some 3.73's and a short throw shifter cuz if your shifter is nething like mine you deifinately need.. get those 2 things and you should have no prob with 99% of our foreign f**kers, your not gonna be able to keep up w/ 4th gens or even newer stangs until u get a 350 but u should be able to hold your own with the 305....just be careful watch out for sleepers...

ChrisFormula355

I guess you guys just haven't raced an LS1 that has decent gearing then, because with good gears, the somewhat high torque RPM doesn't mean squat cuz the engine revs up too fast to be hurt by it anyways. There is this near stock 99 LS1 M6 t/a here in tucson with 4.10 gears, a few intake mods and a chip............he runs 12.50's with a 1.7 60 ft. I'll be damned when I see a 305 run a 1.7 60 ft! 305 do have their place though, I'm not knocking them, I had my girlfriends 305 camaro running 98 mph in the 1/4 with a 3,400 pound Th350 auto setup, and that was pretty damn impressive. It would hang with my friends 13 second firebird for exactly 2 seconds, then he'd fly away

He has the stock 3:42's and yes gears help tons on LS1 cars. You are not joking about reving fast. They sorta start out slow and then just go ape past 3 grand and seem like there is no end to each gear. he even asks me "I want the low end surge that your car has." To which I reply "dude, you got it all with that car, I got a little low end and thats it"

I don't see any 305 hanging with an LS1 either. Have you guys ever checked out a dyno of an LS1? It's the flattest torque curve you will probably EVER see. Hell you probably shouldn't even call it a curve, more like a plateau! I can't find the scan of my friends 02 WS6 (Which dynoed in at 295 rwhp off the showroom floor!) so this is the only thing I got for now. Hopefully you guys can see it. The LS1 has more torque than your whole 305 has at 2000 rpms! Now that's power!

I have raced one mustang 0 to 60 and lost by a fender. I do not know anything about the mustang except it was a 4.6L. My L98 auto will smoke it off the line and on the highway.

90Iroc-Zee, you have a very rare combo, I saw a 90 iroc with a 5 speed for sale for $8k today. If I were you I would try to keep it original. They made very few of those cars. I think the 305 would be more fun to build just to be different. You don't see every mustang guy slapping in a 351.

RBud350tpi

Ford 302= 4 inch bore and about a 3 inch stroke. Plenty of piston over the rod to make HP. Chevy 305= 3.75 inch bore and 3.48 inch stroke. Plentey of stroke to make torque but that is about it. The mustangs that have 351's swapped in part for part are making more power than the 302.

wes2k3

OK, so maybe I should buy a mustang and not a thirdgen .

RBud350tpi

Buy a L98 3rd gen so you have a 350 with a 4 inch bore and go smoke some mustangs.

I have seen 305 cars that would eat 4thgen cars for breakfast. However, they were packing lots and lots of boost.

Anything can be done with the right amount of money, time, and patience. It's all about what you want and how you want to get there. If the 305 is free, and already out of another car, why not disassemble it, rebuild it with some good internals, and boost it?

wes2k3

I'd rather find a 327 and stick that in or use it to make a CHEVY 302 :lala: . 350 would be nice but my insurance company doesn't see it my way.

I am gonna give the motor a once over. If anything new bearings and a fresh hone. gonna port match n polish the heads.

I got a wieand stealth idle-6000 rpm intake
gonna get a comp 262
has small tube headers already.
I live in a no emmision zone so I can do pretty much what ever I want. Long as it not too loud no one will mess with me.

gonna try and get a nice 600-750 cfm carb off ebay but i may just run a moded q-jet. I got an old full manual one laying around.

I would like atleast 300hp.

not gonna go too crazy cause if I do I might as well have a 350. Honestly I had plans for a 4.3 mod but the 305 is free and runs great, easy swap drop in.

Killing all the computer crap, well some of it may need to stay fo the gauges. But I can tune a car better than any computer and all I need is a volt meter and and O2 sensor.


I have no problem with my 2.8 now so I figure the 305 will just make it easier. cause with the 2.8 it will get up and move but you gotta do full redline shifts or you might as well just give up.

the 2.8 is like a 600 bike, slow or fast is your only option. If your sloppy in any gear or short shift your screwed.
