85 and Willie some people dont have as much as clue as need be. If the shop, deer hunting, and lack of sleep dont get me, staying awake trying to get that in their head will. 1 sbc is like another.

Wonder what the world would have ever done if the 350 was never made?


82355 I just caught your statement you have how many 350's free? Where? I can one way or another can have arrangements made for pick-up. Though interested in the 400's more so.

 

It says where I am from in every post I make.

Built 302's, 327's, 400's, and made fun of 305's.

Hmmmmmmm building a 400 which is known for steam ports and overheating. Or 302 which were known for eating more bottom ends and rods.
Lets not forget a 327 which couldn't survive in the increasing smog era, THESE motors?
Though all of then are fine motor's mind you, but let's not forget that chevy(or the fact they had to meet epa's standards) in their demands for more out of their engines (emission wise) discontinued them, and brought out the 305. The 350 itself almost became a dinosaur as well during them dark hours.
Which almost completely replaced the 350 (because it was slated to be discontinued due to emmisions trouble) and even plans made to build the vette with a 305.
Either way the 305 preformed well, not great, but well against all that was thrown at it. (Read next paragraph and you will see why my choice of words was well). This comes from a company that had a greater problem then Ford for passing the emissions. G.M in their infinite wisdom spent more money meeting EPA, then they did on preformance. They left the rest to aftermarket that was already there. Why shell out more for preformance gains when someone else will do it for you has been there approach on a lot of things.
Hell in 87 350 auto cars were only 3 tenths faster then the 305 stick cars from the factory. Almost a complete 45 cubic inch difference! Stick or auto thats terrible, and dont justify the extra cost of the 350 cars. If the 350 if so damn good then why cant it take the 305 in stock trim by a greater margin? Or leap over the famed 302 as well? Not the Chevy 302 either.
But yet again, with these points made somewhere you will pull off it would be more feasible to move from any given power plant for one larger which is fine and does provide power, but I stated long ago what I dynoed at, and with as little as 1500 total into a build (using todays prices and neccessary parts) I can't see why not for the thought on stroking. Plus I dont have to mess with gathering parts to wake up an already working system that has alot more potential. Remember Costner stated 'You build it they will come.'
It stands true with anything you are trying to achieve. When smallblocks or big blocks aare concerned.
I'll go as far to say I run the 334 in the Monte Carlo not the F-body third gen as you stated would be a boring event to watch bet it could open some thought's if you opened your eyes.
That and the fact I weigh more then then f-body and have more dynamic drag.
Seeing it doesn't run any power adders, just motor not too shabby is it?

 

^Very good post

 

Forgetting the debate of if a 305's potential... Why would you want to use a 305 block just for the simple fact that parts like pistons & rings are more expensive & you still have a smaller engine? If I were going to rebuild an engine I would not use a 305 unless 350's suddenly vanished... Yes a 305 can be made to perform, but it will never perform as well as a 350 built with similar parts.


I'll also add the argument comparing stock 305 cars vs 350s isnt really a valid point.

Put the same transmissions in the cars along with the same gears etc & you will probably see a little bit more than the .3 mentioned. Once you start changing things to improve power output & the gap between the two will get bigger.


I'm not trying to say the 305 is total junk or anything... it has its place. That place is not really in a performance oriented car though.

 

^ Very good post.

(look, I can be a nut swinger too!)

Martin

 

^ No, your just a nut-sucker

 

Uh huh . . . . . . .

Martin

 

The cost of rings and such isn't that much more for the 305 then the 350. I can ask you why should I buy a 350 block I dont have to build the motor in the first place. Just so I can say I built a motor cheaper?
Here $400 gets you a useable but needing some work junkyard jewel. The 305's rings and piston's are not $400 more then the 350's. Also if you read earlier it was stated up there why buy what is not needed in simplier terms.
The stroker kit between 334 and 383 are not that much different in cost either and contain all the rings pistons crank roads and such. Already balanced and 1500 with the kit should complete the 334's build.

Did you read any of this post before asking?


Comparing stock to each other is yes a valid point. If they (350's) were so good as everyone wants to think and there is nothing else ( valve shrouding 305's) to build but them, why in stock trim do they suck so bad. As far as that goes what you are saying is only can be compared if the 350 is built well hmmm.
Yes a tranny swap to the stick for the 350 would help the 350 pull farther away from the 305 but not by any more then a sec or two. Using the same gears and such as stated well in my minds eye it better just flat beat a 305 by alot more then 2 sec's. This is comming from car's running stock trim 14.8 for the 350 and 15.1 for the 305.

The power output of a 90-92 Camaro z-28
ohv V8 5.0 / 305 220-230 horsepower 290-300 torque
ohv V8 5.7 / 350 230-245 Horsepower 330-345 torque.http://auto.consumerguide.com/Auto/U...arreviewspecs/
The link the numbers pulled from. Someone who didnt even care about car mods and reports fair pricing as well.
I know G.M seriously under rated the 350's potential and you will scream it all day long and that why it's unfair comparison. I can also say they under rate it for the 305 as well by the same margin.
So that would be futile.

As for building just as asked earlier are you afraid of running a power plant a little different from the rest? Because that would be the only reason not to build a 305 if that is what you already have let alone stroking it. The 305 responds to everything the 350 does and well provides power as well.
We heard valve shrouding to ours eyes hurt and our asses were sore from sitting in front of a computer screen reading such b.s.
If valve shrouding was such a big problem the 350 should have run out and left the 305 auto or stick!
So I ask in stock unmodified trim the 350 has yet to prove it's expense to me why not build the 305 it is not any different of an animal.

Also for anyone stating a 302 against a 305 here is another link that may interesting for you.
82355 no I am not a member of them either but I do read there boards as well. I read several as a matter fact because I like unbiased info.

Remember the 60's horsepower ruled. Welll hmmmm.... torque took it. Adding more to achieve torque and it gets better and even a wider points stance.
Thing is I am picking on a legendary car with an exceptional motor and doing it well.
Using unbiased FACTS.

I payed like 50$ for my Federal Mogul rings Last I looked 350 rings weren't much more/less....

 

Wow...

zjr:

I think just about anyone in the USA can find a free or next to free 350 to build

Yes I read much of this thread before posting

Where do you get the idea that 350's suck so bad?

Do you realize how much "a second or two" is in this context? & where do you come up with that figure?

I have no fear of running something "different" & I dont consider a 305/334 "different".. different than what exactly ? You cant be implying that running a 305/334 is in any way some sort of bold new direction to take (are you? )

I dont see unbiased facts in your post... I see mostly emotional responses & what few facts contained therein are inpertinent to the debate. You like 305's/334's & thats fine. You seem really defensive about it though for some reason.

 

Part of the reason the L98 cars didn't perform sooo much better was the intake system was designed for 305 use in the corvette. As an afterthought GM put a 350 in using the same intake.

I dont think there's anything at all wrong with building a 305. Honestly though I prefer a bigger bore motor simply to keep piston velocities down at a given RPM. This seems to help with engine life and also I like revving high. Its easier to rev a motor that starts with lower piston velocities. Its easier to build power on a bigger bore motor vs a longer stroke motor of the same cu in. Bigger bore motors also seem to respond a little better to mods as well.

The person who mentioned earlier that the 305 and 350 were the same animal is wrong. Bore, stroke, piston velocities and a host of other things are different on 305s when compared with 350s. These make a difference when building a performance machine. Both have great potential and I'm on the market for a TPI 5 speed car, which as we all know only has the 305.
They're good motors, and respond to mods and you can look around and see plenty of folks deep into the 13s and even into the high 12's on 305s with no forced induction.

 

im turboing my 305 now, what turbo do you have and would pics of your set up be posible? what are you doing for fuel?
