My friend's BS cntd...

[Al]

I'll just refer to my friend by his name from now on because so many know him somehow.

Troy was trying to convince me that the old "boat anchor" 305's were all pretty fast...as in low 14's fast. He claims that there was never a 305 that ran a 15.

With the exception of a few Z28's, the 80's and early 90's 305's out of the RS camaros were turds...right?


Our arguement came out of an arguement about me beating the "turd" 305's back when I had my prelude. Back then, I always assumed that the Z28's and higher all had 350's in them. Troy is convinced that there never was a v8 camaro from the 80's that took more than 14 seconds to complete the 1/4 mile.

*additional note*
I hate it when people bs in certain situations. The arguement before I brought up the statement about 305's was when I raced a kid with a built motor who claimed that he had a stock 305 with straight pipes on his 84. He popped the hood and I saw an aftermarket air filter and that was about it. I told him that I didn't know what I was looking at.

We raced...I lost.

Turned out that his 305 was a 389. He told me so right after the race. But everyone else still says that an old 305 smoked my car. Which, obviously, didn't happen.




Sooooooooooo...
What did the "boat anchors" run?

[Crazy Z28]

My brother has an 86 Z28 305 5 speed and it's a turd. It even has a four barrel. I couldn't exactly tell you what they run but his can barely beat the old style chevy trucks with the 5.7 Vortec. His is stock except punched out cats and is in farely good shape so I'd say it runs about what they would have when new. I don't think any of them would be even in the high 14's though. I could be wrong, but that is what it feels like to me. :)

As far as I know, the only 305 car to hit 14's were those with the TPI setup and a 5 speed. A friend of mine ran his at the grove. His was bone stock but it did have some minor exhaust work. He ran a 14.999999999999999 once and than did consitant 15.20's the rest of the day. So, yea I guess he could say it was a 14 second car :confused . His was an 87 Z28 TPI car with a 5 speed.

[UnderPSI]

I had a TBI firebird formula that I got to run 13.4-13.6 more than one time at the grove. Plenty of people saw it run as well as saw the timeslips. It wasn't easy, but it can be done

[PARALYZER]

We had a 92 Trans Am with a 305. Ran 15's all day long. Don't even say driver error either. It was a turd. Heavy car with only 305 cu. What do you expect? plus it was an auto.

[Nix]

They are nice cars but as I always say (Quote)*You cant polish a turd*! It was just a horrible motor, hence they dont make them anymore. The 5.0 mustangs had their glory day back then by being able to crush the shi! outta the the boat anchor. The 302, destroyed the 305 by a mile back then.

[PB86MCSS]

I believe it wasn't too rare for the 5 speed TPI f-bodies to run 14's out of the box, high but still 14's...IIRC. I think its pretty much common knowledge that 305's stink for breathing, etc....people can and have made them pretty quick but it will be easier and cheaper doing it to a 350 ;). Its a good motor, just not for performance.

[WilliamZ]

I don't think I ever won against a 5.0 Mustang with my 86 Trans Am. I had a 305TPI auto, with a K&N, Flowmaster exhaust and a Superchip ;) It was sloooow but it did sound good :D

You won't be losing to 5.0's any more or 4.6's or cobras or...... :D

[Lash]

A guy I know has a 89ish trans am.....305 auto. ran a 10.xxx@63mph 1/8 mile....do the math :D 0-60 in roughly 10 seconds. :eek:

[lotsals1]

the 84 or 85 3o5 t/a high output --i know someone who had one that ran 14.4
the car was pretty decent for what it was --the thing was stock also

I had a 91 RS 305 TBI 5 speed that I stuck WAY too much money into. Had the block punched .40 over, bigger cam, head work, aubourn possi, 3.73 gears, centerforce dual friction clutch, edelbrock headers, flowmaster catback, hypertech thermomaster, b&m short throw... Maybe more I'm forgetting now but who cares. It ran a best of 15 flat at about 90 MPH if I remember right. It felt like it had a ton more potential, but a 15 is a 15... Oh well, I had to post this before Max 93 saw it and rippid me a new one about it.. :goof

Oh well. I was young and dumb. I learned from my mistakes and started out with a MUCH better platform this time. This time I did the work myself with Max 93 as a teacher. Saved a ton of money and learned a lot!!!

[BadAzzGTA89]

350 TPI was the way to go in 3rd gens but GM didn't want to put the torque monster to a stick??Why not I can run newer gt stangs and machs and just beat them almost stock!!
No i don't know what i run in the 1/4 and never will!!
Mine is never going to be stock again!!And to 305 f-bods bring it!!!

I agree and used to wonder the same til I saw what Chevy High Performance Magazine did to a T-5 they mounted to our motor. Yeah, it lasted 2 passes...

But to give you an idea, that RS I mentioned ran side by side with my friends 69 Gutless that walked every GTA I saw it race. Both of em. :goof But my friend has a 88 GTA that feels like a dog compared to my car stock and mine ran a 14.2 then. So that might give you a neighborhood of what your car was stock. Too bad you didn't get a baseline so you had numbers in front of you when your project is done.

I was tempted to build up my 305 TPI motor, since I didn't *want* a ton of power and the motor was already there...but better judgement got ahold of me. No more 305's for my cars, whew.

I have very nice headers/catback with a L98 cam in my 305 TPI motor, K&N filter and 3.42's but the car runs like a dog. Not sure if there is some other problem, but no codes and it ran relatively efficiently getting 18-19mpg mixed hwy/in town.

This time doing whats in my signature, hopefully it gets me into the low 14's considering its a peg leg, should have at least 300hp....supposedly just adding Vortec heads/SDPC intake gave an otherwise stock L98 over 300hp according to Scoggin Dickeys site. Throw in my exhaust and a better cam, who knows. Not a world beater but enough to wax most rice with I hope, in a granny car.

Oh yea, anyone want a one peice roller 305 long block in a month or two? I'll have one :rock: .

I'd be suprised if a 84'-85' LG4 or even L69 and 5 speed f-body can crack 14's...guess if he had nice gears and knew how to bring it its possible, I always thought the only 3rd gens who got into the 14's were the 350 TPI and 305/5 speed TPI cars stock...besides the TTA.

[theavenger333]

my last true beater i had was an 84 camaro with the 2.8 v6. had like a BILLION miles on it, i used it as a screw around car, milled the manifolds and it had no cats, it was an auto too. i ran a prob 87ish 305 camaro with that thing screwing around, and only was behind like 3 car lengths, so that is a very good answer i would think

The deal with that kid and his 389 is that he used the 305 block and 305 heads. Add headers, straight pipes and some other bolt ons and removing useless parts, he only managed to pull off a near-14 flat run.

The current rumor (yes, it is just a rumor) is that he bought a very good set of heads.

[PB86MCSS]

I'd like to know how he managed to get a 389 from the 305 block....I've heard of 334" stroker 305's or such, but nothing higher than that ;).

He must either be BS'n me or I have the info wrong.

It could be that he was just using a pair of 305 heads on a 350 block?

But I know that he was running the 305 heads.

its a relatively common trick to put 305 heads on a 350 because they have smaller combustion chambers and thus up the compression by a bit.
