    Wood Floor Test Panels

    Looks like gun mix polyester resin. It would be interesting to do a mechanical test of the bond between the resin layup and the wood. Polyester reputedly does not bond to wood anywhere near as good as epoxy, which is an excellent wood bond. On a plywood rod floor, a layer of 12oz cloth (not...

    Busted bolt

    Back to the locked up motor. My nasty suspicious mind thinks that engine had, or developed, a water leak, head gasket, manifold or somewheres that let a dose of water get into a cylinder or two and corrode her up big time. Seen it before, and you did say it was only run for a few minutes before...

    Fiberglass time........ugh

    Another really useful adhesive for this sort of work is builders glue. I have wooded out a few glass bodies with the stuff now and it is way strong. I use the extra strength, one hour setup one. It won't sand up and fair like body filler does, but it is slightly flexible when set up and seems to...

    New Carb

    IMHO the great thing about a vac secondary Holley is, you can effectively size it to the engine. A 600cfm Holley like the list 1830 will flow about 300CFM through the primaries, and as the rating says, about 600CFM through all four. The vacuum signal from the primaries "tells" the secondaries...

    firewall mounted master cyclinder

    http://www.classicperform.com/tech_articles/GotBrakes/GotBrakes.htm Here's another way to do it. 90 degree linkage and the MC and booster (if you have one) sit up under the dash out of every things way. There are a number of store boughts and you can make your own, you that way inclined. My...

    Alternator Question?

    Good thinking by the Potvin Guy. What is happening is, the regulator in the alternator is a voltage sense device. It tends to track battery voltage in an effort to avoid over charge on the battery. When a load goes on the battery, the battery does work and the terminal voltage drops to reflect...

    Alternator Question?

    Everything seems normal here to us Auto Electricians, Swampdog. Fully charged battery shows around 13.8V at the terminals. Your fan will use about say 6A (that 40A for the relay is a current carrying rating, not a load) and around 120W of lighting load will take up say 11Amps, and lets not...

    And now for an IRS horror story

    What Fluidfloyd said. The lower control arm ("LCA") rotates around the inboard attachments. Your trailing arms rotate around a centre a much longer way outboard, and they will move the outboard end of the axle forward and back around the arc radius centered at the forward attachment for the...

    VP racing fuel

    Hey Screamin'. Makes us down here in the South Pacific feel quite fortunate as far as the fuel and emissions regulations we get to work with. I wonder, engine damage wise with an old classic without ECU and knock sensors, the RON is the fuel rating to watch as providing some insurance against...

    Fuel Line

    E85 is a wicked waste of good corn. What Screamin' said. Real engines need real gas. JM2CW

    does anyone know what a good size of front tires i should use?

    BTW of course hard to tell definitively from the photos but it don't look like you have much caster on the kingpins there. IMHO 7 degrees or so is optimal, and because there isn't a lot of weight on the front end you can run a bit more without the steering becoming heavy or trying to self centre...

    Wiring gas gauge & sender

    The reason why the gauge manufacturer wants you to run an earth (or ground) wire back from the tank to the gauge is because he wants to eliminate resistance in the gauge circuit as much as possible. The sender itself is a resister device, and any extra resistance in the circuit will introduce...

    Timing for 350 Chevy SB

    Really hot to me and a lot of others means boiling the coolant. This means you are over 212F or 100C coolant temp, to be practical. If the coolant vaporises (boils) it will blow out the overflow. Another thing to make the coolant blow out the overflow is gas leaks from the head gaskets or...

    Carbon fouling plugs

    Only reason you might drill the primary butterflies is if you running a decent cam and there is no manifold vacuum to speak of. That 302 is a stocker so should have plenty suckuum. Never seen butterflies drilled in an Edelbrock carb anyway. I would check the bowl levels, if they are around the...

    front end bounce issue

    Don't forget the steering damper is parallel with the tie rod. Rapid lateral axle movements will move the tie rod and thus steering arms as the damper does its work and very little is felt in the steering. I have had the exact same problem, learned the hard way. There are very good reasons why...

    front end bounce issue

    As Potvinguy observed, your front end has no transverse control. You need a Panhard bar. The symptoms you describe are of the front axle oscillating from side to side, bump steering itself to even greater excesses until the front end components contact each other. IMHO that pretty little front...

    Vacuum Pump for Brake Booster

    Yep, that's what I'll do. Just e-bay'ed me a Ford pump with vacuum switch in, got a 2kg BCF fire extinguisher that will make a dandy tank, and it comes with a ready made mounting bracket as well. Whooopeeee !

    Vacuum Pump for Brake Booster

    The electric pump stowed outa sight appeals. So how do we plumb the vacuum part. Do we involve the inlet manifold, (Victor in my case) or skip that altogether and just use a pump, low vacuum idiot light and a reservoir? That route seems better, the manifold isn't going to contribute much and it...

    Vacuum Pump for Brake Booster

    I wonder what my brothers are doing to solve the lack of manifold vacuum problem when running a decent amount of camshaft and a brake booster. I have always used a vacuum tank and tolerated the dead brake pedal syndrome in traffic. No more. A friend has used an alternator off a diesel with the...

    overheating problem

    IMHO If the only symptom of "overheating" is an instrument telling you that, and it does not agree with any other instrumentation, I would check the instrument. Over the years we have seen many cars come in the shop "overheating" or "running hot", but otherwise running fine and not losing...
