I am restoring a 69 Firebird with a manual transmission, but have not yet found a diagram or description of the engine vacuum line connections (carb, intake, distributor, vacuum valve?). Any help would be appreciated.

I lost a lobe on a new Comp XE 274 cam, 50% gone. I sent it back for replacement. They said I should have removed the inner valve springs (Wish I had now) but it sounds like they are gonna replace it. I am however wondering to what detail I need to clean out the engine to remove the debris. Any suggestions welcome.

Older heads with newer intake crossover port fix?
Right. I now have them and I want to install them. I have it apart, but i notice the water neck from behind the water pump is a problem, and it looks like to me that's a permanent water pump base and to remove it i have to take off harmonic balance due to the fact this base seems to be connected to all that. I have no such experience with Pontiac and no benched motor to see this from a different vantage point. This doesn't seem to be necessary to just change the intake, I am now scratchin my head!!

Hi! i'm new to this forum but i will be spending alot of time here from now on. Long story short.. my boss gave me an engine from his pontiac firebird -68 which turned out to be -71 block with 71 heads(94) and 4-port intake(496140) from 1975. Next summer i'm going to buy his -68 firebird and will have to engines to work with ..the one he gave me and the one that's in the car. Anyway im going to tune up the eninge he gave to me and im very happy if someone could give me some tips on which cam etc i should put in.. i want as much hp as possible with the stock heads (i wont put as much money on the eninge as i've done to my corvette). I've never worked with a carburator before so dumb as i am i just bought some random which turned out to be a carter thermo quad 6-2141.. think it's 800cfm? .. i might be wrong. Is this carb something i can work with or should i buy a new one? :( I've sand blasted the whole engine and will put it apart this weekend and i've started to look at parts i will be buying. If someone can help me out alittle that would make me very happy /regards the swede Daniel

Hello i want to repaint my survivor Grand Prix (14000 miles from new) in its original Anaconda Gold colour. Althouth its a low mileage car and the interior is still brand new, the one previous owner unfortunately ruined the paint by covering it with a plastic sheet after a rain storm and before the hot sun came out....... anway the car is with me in the UK now and i cannot get a match for the colour. The body plate has the code 63(S). ie anaconda gold accorning to some research i did, the various US suppliers had the following codes: Dupont 5434-L Ditzler 2448 Rinshed Mason A-2562-D but none of this relates to any paint (even Dupont here is diffrent) avaialble here on a computer check at any paint shop i have tried. I have been through countless swatch books too. Can anyone post the formulation or at least instructions as to how to how to get the correct paint - the car deserves it! Carriers will not ship the paint to me from US in anything like the quantity needed, you see. Thanks for your help. Ron

Hello I got a ragtop 68 bird with a 400 that sat for 15 years i had it running once or twice but now I cant get it to start. I replaced almost everything, plugs wires dist, coil, qjet,..., I was going to replace the points with an electronic unit but somehow it got fried and I went back to points. Putting the dist back in I brought up the number one to TDC on compression got spark and fuel but its not starting. I finally pulled the timing cover and found the timing marks at 12 on the cam and 12 on the crank! Doing a bit of searching here I found someone saying the timing should be at the number 6 plug not the number one. any ideas or comments would be really helpful! thanks Steve

Hi all, Does anyone here have experience with either the Edelbrock Vara-Jection or Holley Water Injection systems? I have just started researching the usage and found the information very useful. These systems were used to eliminate detonation when gas made a change to lower octane levels for emissions standards. Today, the turbo/ supercharger guys use water injection it for the same purpose when running high boost to keep the mixture from detonation. The water injection system is also said to increase mileage and power, but in naturally aspirated engines running high compression, I would sway more toward the idea the running your timing to the motors original specifications is where the power comes from, rather than running less timing to accommodate the lower octane to somehow cheat the detonation which still occurs. If anyone has done this, please let us all know because this would be a great way to run the higher compression motors at full timing without the over-heating issues. Many people on the net claim that it works with amazing results. BTW: I just bought a brand new Edelbrock Vara-Jection kit still in the box for $60 at a garage sale. Hmmmm.... Some basic history on water injection that I found from another web site: The essential idea was developed in the first decade of the last century. The original purpose was enhanced cooling. By 1910 some engines which had been water-cooled were simply produced without water-jackets after addition of 'internal cooling', as water-injection was first called. Those engines had compression ratios around 4:1 and the phenomenon of pre ignition (knocking, pinking) was unknown. Later however this became the main reason for water injection which turns out to give spectacular octane improvement, allowing CR as high as 13:1. By the end of World War II many aero engines used water-injection. German versions used water-methanol mixtures, partly because straight water would freeze in winter. The Wright Cyclone, a main U.S. aero engine, tested with water and methanol-water (the two liquids being miscible in all proportions, unlike methanol & petrol), showed 50:50 best (as had the Germans). The results were summarised as "high savings in fuel cost - 52% at 100% power, decreasing to 25% at low cruise powers... pure water is approximately equal to fuel when used as an engine internal coolant at high power". Water gained the Corsair (flown by some Kiwi pilots in the Pacific) 350 bhp on its normal maximum of 2100 bhp - a 17% increase. These were supercharged engines, so the results may not translate readily to normal aspiration. Another alcohol, infamous ethanol, was similarly mixed with water before injection, but was not as good. When Renault attacked Formula 1 with twin turbos cramming several atmospheres of boost into Gordini's 1500 cc V6, they readily achieved 450 bhp, but burned holes in pistons. Then a Kiwi mechanic recalled water-injection; a reliable 550 bhp won the championship. The Saab turbo works rally car at one period had a water tank as big as the petrol tank. Some modern gas-turbine aero engines use water-injection for maximum power at takeoff. Various naval and rail external-combustion rigs are improved by steam injection.

Hello all you pontiac fans!Some questions about my newly bought '80 formula. It has the original 301ci. non turbo with well under 100,000 miles on it.This is documented with repair records.I do need to do some minor repairs ,though. The carb needs a rebuild and the exhaust manifold needs help. It has the "A.I.R." system on it and I would like to remove it and put regular headers in place.Is this feasible? I'm not looking for a power-house car,but I do like the sound!For the time(until there's more milage on the car)I would like to dress it up a bit.I also wanted to change the quadrajet over from the "hot-air" choke to either electric or manuel.Once again, not looking to get high-output from this kiddie-car engine,just want to put it into some nice clothes and drive it on weekends. Any advice is much appreciated.

can we say pirated from ford - yep - George DeLorean (before the car with that name) after the GM racing ban (1963) went with Mercury - Delorean, fancinated by the powerful, high-revving and durable 427 - Delorean delivered the 427's heads, valve train and camshaft to Pontiac engineers - might we say thankyou FoMoCo - the results was the Ram Air V - however, Pontiac engineers used the RA IV camshaft (Delorean described as "junk") and solid lifters - all this happened around 1966 - 1967 - shame the stuff did not get to the real public - could we not say super GTO

If the dual quad and the tri power have the advantage in flowing more cfm, then in theory they would in, say a drag race situation feed the engine as much air\fuel as it wants or needs versus the single quadrajet being a limiting factor at WOT not flowing enough cfm. Am I on the right track or am I missing it in some way?
