    Hopefully, soon, I will be removing the carbs for an overhaul and the distributors for conversion to crane optical ign....(77 308 with 24k miles, sketchy service records),....So, as long as I am in there and things are out of the way what else is easier/ more efficiently done?????

    Here is a partial list of what seems like a good idea as long as i am in there:

    Thermostat & gaskets.
    Oil Pressure sending unit
    All top side coolant hoses.
    All evap and fuel hoses, (maybe Aeroquip for the fuel delivery).

    Any suggestions??? Parts recommendations??

    Does having the carbs out of the way make it significantly easier to adjust the valves??

    I plan on rigging up a 4 point block and tackle system to remove and store the engine cover while all of this is going on.

    thanks,
    chris

    If I had all that stuff off I would go ahead and adjust the valves. In fact I would just go ahead and do the belts and get it all over with so you can just drive it for a few years and just do fluids.

    FWIW I would replace all the fuel lines with good rubber hose. It is a far superior product to the fabric covered hose and does not come out looking like a high school kids Camero under the hood. But that is just an opinion.

    As for the ignition have you given any thought to a full electronic coil on plug system? Get rid of the distributors completly? Those look like the hot setup. Problem with any of the systems that keep the distributors is that you still have to service them just about as often to keep the advance system working. And with electronic advance, those systems can optomize the advance for better performance and better mileage, something the Marelli's were never designed to do.

    Brian,

    I know it is the way to go, but there a lot of things that i want to do like 360 rims and tires, bars, catch up on a lot of maintenance upgrade the brakes and so.. i opted for the low dollar low maintenance fix.

    thanks,
    chris

    Skip the wheels and stay focused on the mechanical maintenance. Don't bastardize the car too much if you are ever planning on selling it.

    Judge,

    I would agree that mechanical maintenance is more important than performance upgrades, particularly in view of the "Gates Rule", however, i feel that "bastardization" is perhaps a bit too strong an epithet to skewer me with.

    Life is short, I very much enjoy being imersed in the 308 project, (maintenance, improvement and driving). The stock 308 wheels preclude the use of modern high performance tires. This particular modification is fully reversible.

    Now,if i installed a cadillac style padded landeau roof, wheel well lights and a 8 inch chrome muffler tip with white wall tires and a boooom-boooom mega stereo, I might agree that I was a feckless drooling turd.

    But since I am pure of heart and really love my 308, I beg your forgiveness as I stray from the pure original stock to a more enjoyable updated machine.

    With malice toward none and the throttle flat on the floor,
    I remain,
    chris

    But it would be cool. I always dreamed of a black TR with a flame job. I would drive it to every Ferrari event and park it right up front.

    Chris,

    No offence was meant. I judge concours events. Anything that is not original, is bastardized.

    End of the day, its your car and your money. Do what you want. I'm just trying to help you if you ever plan on selling it.

    The 308 is a great car as is and one of the best cars from its era. Maybe I'm the odd ball that doesn't understand why everyone is trying to make it as fast as a modern Honda Accord.

    Cheers,
    Erik

    If you do not plan to make it as near or more pristine than the factory, there are a couple of simple (and tasteful, IMHO) options that you could consider based on my limited experience:
    Clean the engine and engine bay per the great Baghwan Spasso's method (see old threads)
    New fuel hoses/filters all around.
    Stainless steel teflon brake lines - you'll feel an immediate difference
    Tires - newest technology tires you can fit on either your stock 14" (e.g. Pirelli P-4000) or fit the popular 16" QV wheels or replicas with SO2s for sport or P6000 for touring. See old threads. The 16" gives you the most selection and bang for the buck in tires, and Ferrari did the wheel engineering for you.
    Muffler - this topic has been 'exhaustively' covered elsewhere. :)
    140 carb main jets @ $6.00/jet
    New DCNF air horns made by Durable1 shown on Dyno with about 10 rwhp increase and no loss of torque; About $30 something apiece I think.
    Although a bit expensive at $1500, another option Norwood makes a nice single Marelli distributor conversion using the new technology internals and improved advance. Would also add an MSD.

    Just some simple ideas to mix and match; nothing extreme.
    Enjoy your car!
    best

    I would definately do the valve adjustment, belts, change all the coolant and fuel hoses (upper and lower) and check all electrical terminals. 16" rims are the way to go, especially if you go with QV rims or the 328's.

    Also, do not forget replacing the fuel filler neck hose..the one that runs between the filler neck and the gas tank....they rot out and can crack and leak when filling. Guess where the fuel that leaks ends up? Splashes right on the exhaust system!! I had my mechanic replace mine (78 308 GTS) after reading about a 308 fire while filling the tank over on www.tomyang.net.

    I still have it, and man was it cracked and rotted...just about ready to let go.

    Mine was too! Not leaking yet but cracked up really bad. I replaced mine with a fuel grade piece from NAPA P/N 1055, cut to length and secured with new Marmon clamps. Better than factory.

    I would like to add that going with the QV 16" wheels is what I did, allowing me to buy Z/W rated Yokohama AVS100 tires. I retained the traditional look of the car but stepped up to a low profile tire with softer compounds. The handling improved greatly. The cost was far far less than going through the hassle of 360 wheels, spacers and tires (big $$$$). Of course this is all subject to ones own taste and budget.

    Good luck!

    Eric,

    I would agree that stock is best to preserve the resale value of the car, I have no interest in racing hondas, but i would like to tighten up the handling adn do what i can to bring the car up to date, reduce maintenance, eg ss brake lines optical ign, msd.

    Russ,

    Ive done the ss lines with the front end o haul, went low dollar, (again) witha nice tight flowmaster system. The po did dual msd. Wheels and tires still undecided.

    Jay, I'm trying to limit this stage of work to a "top" rework. After reading about Verell and J. Wise going through "a little extra work" to get rid of the bearing problem, I'd kind of like to have the top side done first - know what i mean???

    Dave,

    The po did the fuel filler hose, i'll do all of the rest, i mean every fuel or vapor carrying hose.

    Michael,

    Doing the intake manifold gaskets and matching them to the head and manifolds sounds like a winner, as long as i'm in there.

    Does anyone have a recommendation for the vacuum booster hose?? Does this miserable pulsing bit of fuzzy hose go all the way to the booster or is there a pipe in the chasis. I don't know what or how much to buy.

    Thanks for the help guys, appreciate the advice,
    chris
