Blowers, good or bad for street rod

I was thinking about putting a blower on my 350, and whould like to know if that a good idear or not, I know the cost is around 2,500 or so,or maybe a tunnel ram with two 500 carbs, somebody told me that you need good compression to run a blower, I just like the look, and want one befor i die, no track stuff just street fun.

 

'good' compression for a blower is around 8:1 cr.
You could get away with a little more cr if you don't let the blower work too much.

 

Putting a blower on "almost" any car is an instant improvement, I don't think there is any other mod to get more HP/$$$ out there, well maybe Nox, but that wouldn't make it "traditional" would it...

Do a little research on here and compare the blower and tunnel ram threads, there are many who think a tunnel ram is **** and many who like them, but I can't remember anyone not liking a blown engine.

I know how you feel about he "look" of a blower, I have a friend who has a blown small block in a 34 Ford coupe, I get way too excited evertyime I hear that engine run, I love a throaty exhaust note, but complement that with some blower whine and I'm like a kid at Christmas. I am planning on putting a blown flattie in my shoebox next year.

 

I hate blowers..

 

If you can affordit, do it! As said above, make sure your static compression ratio is low enough.

 

Its a great idea!!! It will be one of the greatest days of your life the first day you get to drive it. You'll be able to blow the tires off at 45mph in high gear. What more can I say. WEEEEE FUN FUN FUN.

 

good can I have your, I had a 40 like that, no blower of course, I wish i still had it. the only thing that looks better then a small block with a blower is a big block with a blower. I like it.

 

Ive had both and they both can be made to run very well on the street. My choice is a 671 blower just remember low compression and blowers requier big carbs like 2 800 edelbrocks work nice, anything smaller than 2 750s will run lean at wide open throttle. Enjoy

 

If its not blown.... it ****s.

 

There is definitely a cool factor and they make big power. I would think a stout forged crank would be a good thing due to extra load on it and forged pistons if ya want to make big dog power reliably. They are heavy also. Nothing quite says "I've arrived" like a 6-71.

 

here one I was looking at http://www.speedwaymotors.com/p/4030,,_6-71-Street-Blower-and-Supercharger-Kits-For-392-Hemi-SandB-and-BandB-Chevy.html?itemNo=BLOWERS

 

For a 6-71 with a gilmer belt on a SBC - forged crank is a must for longevity. They put a lot of load on the crank snout and tend to break them off on cast cranks! A four bolt block and forged pistons are really nice to have also. You can get by with a 2 bolt block through about 500hp if its studded. Forged pistons pay for themselves if you have ever have a tuning issue.

I personally like the Wiend 6-71 blowers for street use. They are pretty dependable for street use and priced well with good instructions. They are not a race blower and will not make as much power as others, but they seem to last a long time.

 

Thats a nice on I just dont care for the name on the side of it. Im gonna use a Dyer's gmc cased one. Its dosent have all the logo's as the one your looking at, plust they are the same price. Just look them up on the net or I can get you the info if you want it.

 

Go for it , i've been running them on the street for the last 25 years or so. a near stock 350 chevy with a 6-71will make about 550 hp. and a ton of instant torque. a good cooling system is a must , keep the compression ratio down to 8.5/1 or less and use a cam with a wide lobe center angle.

 

Blower's are more than cool... they can be 'Kühl'.
Below is mine, it's a larger 8-71 though, awaiting patiently for me to start building that engine for it.
I've got a manifold for a bigblock Chrysler for it, which came with the deal, but I would now rather mount the blower on my recently acquired 392.

 

I have a 1974 350, .30 over, about 9:1 compression, 144 B&M street blower at 7psi, turbo 350 and 8inch rear with 2.73 gears. I get about 20mpg and can boil the 195 Cokers off. It goes from zero to speeding ticket in quick!

Been running this setup for about 5 years, no problem-MIKE

 

My old '36 coupe with a BDS 6-71 blower.
The sound is awesome.

here is a good scoop on blowers http://www.chevyhiperformance.com/tech/engines_drivetrain/induction_poweradders/0610ch_superchargers/index.html

 

Somebody call 911, this man is obviously near death

 

Ha Ha I had y'all going. Blowers rule. Mine has been on my '37 since '97 and I beat on it regulary. She pulled over 628 on the dyno and with a street tune she has logged over 12,000 miles. Go for it...

 

nice!
I just mite do it, I was always kind of backward, I'll start at the top and work my way down. blower frist then cam,fule pump,what ever.
just have to keep the boost down. like that word Boost, Booster. can't be a booster with out a blower. I think thay got a booster club someware must be for cars with blowers. thank for the input

 

me too, they cost a lot, weigh a lot, eat more gas, break ******s and rearends, and waste tires.

in other words, a blower is a must

 

I wanted a blower all my life. Ever since I was 6 at least. I heard a truck pull in a local cruise night with a huffer on it and asked my dad a million questions about it. I finally got one 24 years later. It's totally worth it. Just make sure you set everything up right. If you run 8:1 comp. you really don't have to change much. It's a good idea to run a blower cam and carbs if you can. It's not necessary though. Good luck. It's definately worth the $$$$.

You forgot that the Blowers themselfs can go bad too.

I'm going to get this one rebuilt again, so I can burn some more gas break ******'s and rearends, waste tires, etc....

 

yeah, that's part of "they cost a lot", over and over again!

 

Very Seventies style, but whatever floats your boat. I like them. BUt sometime get dissapointed by dismal performance by the show boats that tend to run them.

 

Yeah... It sure is...

But man, when you stand on the Throttle....

 

I love mine,

BDS has a deal that seemed to me to be very reasonable. On 671's you can pull it off, ship it to them and they will go over the whole thing, replacing what is needed for around $250. You can also have them repolish it for around $100. I didn't think that was too bad compared to the startup on one. Just a thought...

Nothing like a blower, you can run a normal compression ratio above 8:1 but no boost, just the sound and look, but as said before, a good grank is needed for the load on the snout, now, if you build it for the blower, then boost is good for the soul
