Please bare with me as I am just learning

I'm rebuilding a 305, first project ever, and I have noticed that there are 2 different types of intakes. My question is, which one is better?

Single Plane or Dual? Why?

 

Dual plane intakes provide better low-RPM operation by splitting the engine into two halves. Less interference between cylinder pulses.

Single plane intakes produce better high-RPM power.

Most likely, you'll want a dual plane intake for street operation.

On a side note, why, oh why would you rebuild a 305??? (and don't tell me it's because that's what you've got)

 

Well partly its because its what I have. I never re-built an engine before so I figure why not? I'm thinking of stroking it out and shooting maybe 200+ nos on it. In a year or more, I can get a 4 bolt 350 block for free out of a truck and then work on that. I am saving up for a 502 for the RS thou

 

I suppose it depends upon what you mean by "rebuild". If you spend a dime at a machine shop on the 305 shortblock, it's an absolute waste of money. As bad as spending money on rebuilding a 305 is, stroking a 305 is 10 times worse. Spend the money on the 350.

Which intake you use really depends upon your usage and cam. More details needed there.

 

Hrmm, I am begining to see everyones point on the "ditch the 305 and get a 350" I am awefully low on funds, but dont want to wait forever to get this thing running again. any clue as to where i can find a cheap 350shortblock?

 

imho it depends on what you are using the car for

as a daily driver or to "build up" and expcet soem decent power out of

although alot of the 305 engines such as the L69 werent weak output either, for their size, 190 horse net, so..

for about the same money you could pick up a good used 350, or stock rebuild a 305

it depends on what youre after and want from your car really

good luck

 

I say go with the 305. I just like the look on peoples face when i say it is just a 305.

 

lol interesting reason :P

 

why go with a 350 why not a 572 world engine its only 11,000 good god, i am sorry but everytime some one asks advice all i see is you are wasting your time and money on the ??? why not go with a ???

 

You can make any motor fast.

 

sorry about that there is an incredible wealth of knowledge on here and these guys are willing to give up their building time to answer questions. i just seem to be constantly hearing every time someone, myself included asks about building a 305 all we hear is "don't waste your time/money just get a 350, it costs the same" well i have a set of 416 heads i am porting myself thanks who ever(sorry can't remember name please forgive me) i paid $100 i have a set of edelbrock headers with all pipe including the catback for $100 i have a tourqer II intake which i need to trade for a rpm intake cost me 2 hours of my time to change an electric window regulator. now all i need is a carb ($200) and i am set so i dont really think i can get a 350 for $400 that will run all that great if i can i will and stick the 305 in my s10 HEHE

Also that previous post was not focused at anyone in perticular so if i offended anyone i am sorry

 

I have no problems with bolting things onto a 305 to make it faster. My problem comes when you spend money on the shortblock. Bang-for-buck, it just don't work to spend machine shop money on a 305 block.

Can you make a 305 faster for the same money to swap in a 350? Yes, as long as you don't spend any money on the 305 shortblock. Heads, cam, headers & exhaust, intake - all of those things make a 305 faster, and for the money you spend on them you'll be faster than you would be if you spent the same amount of money on a 350 because you won't have enough money for exhaust - and the built 305 w/exhaust will be faster than the stock 350 w/o exhaust.

As soon as you spend money on the 305 shortblock, you've lost the bang-for-buck battle with a 350.

I ran my souped-up 305 for 4 years. I had the opportunity for the "it's just a 305" thing exactly twice in that time. It ain't worth it. I've impressed a lot more people with the 350.

 

I'm a fan of even going with the 400... you can still get them on ebay and they're not too expensive... that's another story though...

and TheDon... what's up with the privet??(Yes, I know what it means in two languages...)

 

This has been debated countless times.

You can make a 305 fast.

You can make a 350 faster for the same money it would cost to make a 305 fast.

I once had a 305. It was fast. Every single bolt-on on the 305 fit on my 350.
(no waste there) When you touch a 305 internally you just crossed the line into selling yourself short.

Some people build 305's for 4 reasons.

1. To be different (which is stupid)

2. To prove it can be done (mw66nova- which is now going BBC "also ran 12's w/ 305)

3. It is what I have (another stupid excuse)

4. To keep the car original (those people usually do not soup the car up anyways)

Excuses:

1. I cannot afford a 350 (to replace everything in the 305 the cost could get you a 383 period.)

2. I want to be different (people like this are usually people who know virtually nothing about cars, if you want to be different then get a 10 second street car. That is alot more different than 99% of cars on the road.)

3. I can stroke it out and make a monster. (again... too much money for too little. This memo gets forwarded to the stupid folder.)


You want a 350 block I will give you one. Come to savannah and I have one for the taking. Now you have no excuses.

 

You can get 350 short blocks ANYWHERE. They have scrap yards with 350 blocks lined up for hundreds of yards. You can also pick them up at swap meets for dirt cheap. Just have to take it to a shop to have it cleaned and magnafluxed.

 

i am building up my 305 with bolt on because
A: i already have it and it eventually will go into my s10.
B: it is a fun little motor i have had both 305 and 350
C: i want a streetable engine for now using stock rear end and tranny
D: it will have enough ***** for now until i get the 383 stroker blueprinted and perfect which will probably be another year (need a custim tranny rear end and blower)
E: i am tired of being told that i should'nt so nanananana na

and remember guy ( EVERY MAN LIKES TO BE BLOWN )

 

Basicly the only thing that wont swap over when if he does build a 350 is the block and pistons. Which are not that expensive.

Hell why not just get a 454. You can find them around here for around 400 lets say another 1100 in parts to put it in and you can keep up with the 4k zz4 motor.

I say build the 305

 

Exactly my point. 305 guys need nitrous or forced induction to keep up. The price it would cost you to supercharge it you would have a nice bad *** 350. Oh well. Good luck with that friend.

 

did you read the post you quoted? the blower is for the 383 not the 305, but thanks for the sarcasm it always helps.
