OK guys I think we need a moment of silence for this Camaro.

kama, wow seems like it was a nice car, I believe the 371 was the Rocket, as the Freiabll was a stright 6 (in fact it is what the current 3800 series by GM are cased on)

wow 20mpg is not bad at all, although if you put a 4bbl on that, you would have got better milage
 
Night wolf using what logic do you think the gas mileage would improve with a 4 barrel carb as opposed to a 2 barrel? Before you answer, you're talking to a guy who's got 3 generations of auto mechanics in his family. So make it good!!

:p:

it's a known fact, gas millage improves witha 4bbl over a 2bbl, a 2bbl carb. has 2 big jets, where has a 4bbl has 2 small ones (the primarys) and 2 sligtly bigger ones (the secondarys) so uless you drive around town near redline, you will get better millage, the 4bbl will only use the smaller primarys, but when you need the extra puch, it will open the secondarys up, and you have all 4 jets working

if you familey is auto mechanics, they should know that, it's just one of those things that nobody really cares to think about. lol

anyway, having a 4bbl is cool, perhaps the 2 most cost effictive things you could to to a pre-fuel injected engine is throw a 4bbl in (Holly is what i perfer) and a high performance cam
 
I prefer Double Pumpers ! Hehehehehe I said double pumper :eek: :nutz:
 
By Double Pumper I dual accelorator pumps and Mechanical secondaries like on my Holley 4150 650 Dbl Pumper thats sitting on top of my Chevelle. The term has nuthing to do with how many barrels a carb is. Just so you know 4 barrels are not necessarily the Best way to go for power of fuel economy. You have to match the CFM up with everything else on the motor. My little 650 is so much more responsive then the more commonly used 750 double pumper. Why cuz thats to much fuel to ram dowm my little mouse ( 355 ) motor. If bigger was better then everyone would be running Dominator 1000 CFM Carbs Why dont they well these carbs are made for Super stock or Prostock Drag cars. You better have one helluva a motor to burn all that fuel your ramming down there...

A "double pumper" refers to a Holley 4 bbl, because it has two float bowls, one in front and one in the rear.

Damn I hate Holley carbs. At one time I could rebuild an AFB or a Q-Jet in my sleep, but I never had any success with a Holley.

I used to love Edelbrock carbs (Carter AFB). Ran one on my '58 Edsel :D

damn, you have a Chevell? I like them. my dad has a ton of old Pontiac's, most notable his 68 GTO rag top with was his high scool car, has the 400 (going to make it a 425) with a 4bbl

my dream car is a 1959 ElDorado, they came stock with 3 2bbls and the upgrade was a dual 4bbl system, you just goota love that 390-345 (390cu. in. 345hp)

there is just something to be said of older cars that are actualy steel and metal, like, I know I would defintly buy a old String Ray and restore it before I plump down $50k for a new Z06

goes for everything, I like vintage audio, our 1974 Arctic Cat Panther 303 (with the Wankel Rorery engine) is a great sled (just got down using it for about 4 hours today) cosmeticaly it has it's issuse but mechanicaly, it's great and runs nice.

just as a side note, I was bored one day, and was actualy thinking about trying to fit a 2bbl on my lawn tractor (11hp Briggs, the cast iron bore, industrial/commerical version, nice engine) oh yeah, I would have the fastest Briggs around here, lol hey, it's worth a try. lol (although I am not going to do it)
 
Home Blown

I had a 1970 Chevelle 2 DR. HT. that I inherited from my folks that had bought it new. It originally had a 307, 2bbl V8 (that is a V-8 with two bubbles). Over a number of years I changed the entire drive chain building up all the components myself except the fully manual TH-400 transmnission that I had a shop do for me. Final result was a 350 with a 671 GMC blower, 2800 stall converter, 3:73 Posi, quad 2-1/2" exhaust. The blower package was entirely home built from a diesel blower I found in a junk yard. I fabricated the manifolds and drive all myself. I used 1/2" pitch Vega motor timing belt camshaft pulleys (which I removed from 4 Vega motors at a junk yard) in parallel for the 2" gimler belt, used a cast iron Q-jet manifold with a box brazed on top with a burst gate valve on it with a big 3/8" steel plate to bolt the blower to. Instrumentation up the ying yang on the back of the blower outside of the cockpit reading vacuum/boost, oil pressure, fuel pressure, pilot lamps for two stages of water injection, soap, rinse, spin, etc. Homemade 4-link underneath. Quad shocks on the back, 90-10's on the front. Truck springs in all 4 corners for lift. Homemade 10" steel rims on the back (had access to a BIG lathe). Dual batteries in trunk for more ballast plus fuel cell, electric fuel pump directly below. All Aeroquip steel braid hydraulic hose for liquids. This 3,500+ lb. baby went 0-60 MPH in 4.2 seconds on street TA's. It also did 0-60-0 in 300 feet, and all it had was manual drum brakes! If I had had the money for real aluminum wheels and some other real speed equipment it would have gone even quicker but wouldn't have been any more fun. I spent days crawling around underneath with a sandblaster (taking the body off would have been a lot easier) and painted the entire underside in black rust paint. Topside I painted it Federal Safety Yellow with a roller! The day after I'd painted it I was in a parking lot of the local hardware store and a fellow auto enthusiast with a custom truck parked beside me and admired my paint job which still smelled fresh and looked great. He asked me if I had clear coated it. I replied "No, I only had one roller!" :) All true! Times got tough 10 years ago and I had to sell it. That car sure was fun. The turbine whine from the blower idler pulley could be heard a block in front of where I was headed. It sounded like you were at the airport.

BTW, a carb with small primary bores and large secondaries is called a 'spread bore'. I was running a small 600 Holley quad square bore on my stuffer with vaccuum secondaries.

This was just the last of a long procession of self customized wheels I've owned and wasted my money on starting with motorcycles at age 16 (a Honda 305 Super Hawk). This was the last, and most significantly the first where I built most of the speed parts myself instead of buying them. I didn't send a single piece out to get chromed. Really did this on the budget side. It was much more personally satisfying too! I have all the tools but now am so tired of getting my hands dirty that I don't even want to change a flat tire anymore.

Been there, done that, got the t-shirt but the damned picture eventually washed off. :(

how could you sell that thing?!?!?!?!?!?!? go back to the guy you sold it to and offer double what you sold it for, really
 
Yeah, I had a lot of sweat and busted knuckles invested in that. It hurts to part with your really dear toys, but what can you do? :(

I found an early picture of the engine build. You can just see the pop-off valve under the blower. There is a white motorcycle valve spring on each side of a rectangular aluminum venting plate.

Let me impart a bit of my personal wisdom here :p:

When I was 19, I bought a 1958 Edsel, with a 361 bored .030 over, Edelbrock intake and carb. It had a C6 transmission in it which replaced the Ford-O-Matic 2 speed. I owned that car for about 4 years.....I had done everything in that car, even had it in 3 parades. More work than I could ever think about. But, time came when I knew it had to go.

It passed through a couple of owners who bought it from each other thinking they could make a pile of money on it. Nobody did. It finally ended up in the hands of a guy who owns nothing but 50s cars as daily drivers. On it's first trip to Cleveland, he blew the engine somehow. He replaced the engine, and drives it to this day. Six Buffalo winters later, the car is a wreck. It was hit in the side, the wheelwells are rotting out, and the rear bumper which I spent $500 to have chromed is now twisted up from a careless driver. It's trashed.....but still rolling.

Here's the moral of the story. Enjoy it while you can, treasure the memories that you had with it, but sometimes you have to know when to let go. If the engine had blown while I owned the car, chances are I wouldn't look back at it with such fondness. As you get older, you realize that special memories and places are best shared with a special person, rather than a car. I could buy it back cheaply today and restore it to its former glory if I wanted to.....but I'd have to give up too much of the present to try to relive the past.
 
58 Edsel

Tim,

So you're the guy! OK, as the Edsel owner you must know the answer to this question that is imperative that I ask. So how many did Ed Sell anyhow? :) Ha Ha. :lmao:

...ahem. Sorry.

;) ;) ;) ;)

Rob if that car was painted black or dark blue it would look like Mad Max's car in the Road Warrior awesome man just awesome you are really a DIY kinda guy ;)
 
yeah that's the thing with old cars, you could make home made stuff, put differnt engines and trannys in and all that, whereas with today, once you have an engine in that car, it's pretty much there, and since it's all ran by a computer, you can't really do little tweaks that make a big differnce and all.
 
Thanx for the compliment Thor. Yeah, I guess DIY is my middle name for sure. :)

Nightwolf,

I think most local laws still permit pretty much unlimited mods to the older cars. They have tight emissions regulations on the new stuff, so it becomes an issue of not passing inspections if the computer has been bypassed, etc. Mods get limited that way on the new cars.

Thanx to dry southern states, there are still old cars in good shape to be had for the few of us that like to work with our hands.

I totally agree with Night Wolf about the ineffectiveness of minor tweaks to today's modern computer controlled engines.

These things are usually so optimised that the traditional tweaks either can't even be done or actually decrease performance and driveability.

Take for example exhaust catalysts.

There is no legal requirement for them here (dumb but true), so many boy racers automatically remove them and put in those humungous big bore exhaust systems. On modern engines when you do that and don't remap the engine computer you end up with a car that is noticeably slower than standard and also crankier to drive.

:p:

The modern engine (especially turbocharged ones) can be tweaked but will usually cost big bucks and require a guy with an electronics degree as well as mechanical know-how.

Hmm I don't know about that, some of the new computers on cars can learn by themselves
