    Hardened valve seats - do they really matter?

    even if they were adequate to start with, castings move and change shape for years until they "season" or Work Harden. especially when vibrated or heated or machined or all 3 or any combination small block connecting rods on the other hand..... the small end is often not in the middle of the...

    Electronic Distributors From Rick Ehrenberg

    More efficient burn, will illustrate shortcomings in mixture if there is still time left to be producing power it should be used. what was adequate on the fueling front no longer appears to be adequate with the symptom you mention. (although air leak at inlet or around exhaust, manifold could...

    1972 Front Disc Brake Conversion

    if your front disks don't stop you it could be a number of things as stated above i'll sling in a couple more... if the pedal travel is short and the brakes feel a bit like wooden blocks your master cylinder bore is too great. you end up with little brake feel and the fat cylinder is not...

    No spark

    believe this is appropriate for both mopar and HEI. on the approach the reluctor peak causes the voltage to swing low and the low dip gets bigger the closer the reluctor vane gets to the pickup centre when aligned though, its at zero because the voltage has to change direction when the...

    1972 Front Disc Brake Conversion

    just to note, and it probably won't be useful with a set of disk brake spindles that match you upper balljoint you can have any combination of big or small bolt pattern hubs or big or small top balljoint with a caliper pads and rotor that fits a 14 inch wheel its just hard work and you...

    Hardened valve seats - do they really matter?

    I have had the exhaust valves done but i had bigger valves fitted at the same time, the shop seemed very keen to relive me of my money and at the time i was not in a position to argue the toss. if you fit stainless valves, the chances of them micro welding repeatedly to the seats in a cast...

    Radiator/Engine temp questions

    i think it could potentially be in the tune. i went from 1/2 - 3/4 gauge reading down to 1/4-half gauge reading with a recurve dizzy new carbs and a better exhaust tuned up right. Or a problem with the stat or cap Or not necessarily the cap, the lugs on the cap and the filler spout profile...

    Electronic Distributors From Rick Ehrenberg

    When it comes to Ricks parts i've never had a problem. really really helpful, and he owns an Aussie charger amongst a range of other mopars..... so he is obviously a good guy.... In this day and age, if you want a Chinese company to make a pre existing product line, to your own specification...

    Electronic Distributors From Rick Ehrenberg

    if the car is manual this may be useful if its not i'll agree something else is wrong on the electrical side of things .... Your alternator can, at the point of an unexpected switch off, produce a spike in the electrical system. when running, the armature in the middle, has a current...

    Windage Tray Design

    or you could make or purchase something like this this one fits a hemi 6 but you have main caps in a different place in a slant 6 so some new holes and some ARP washers under the bolt head onto the bracket might have this working. not as effective as a full scraper set-up but combined with...

    340 Overheat / Radiator Geyser

    Did you buy a new water pump? are the outlets in the right place? i.e do you have a 318 340 one or do you have a magnum style one which is designed to turn the other way due to the different belt route on those later motors. if its running the wrong way it won't work, but your symptoms would...

    Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

    For flow to exist there has to be a difference in pressure in the system between inlet and outlet of the pump.... Doesn't matter how it is created or the type of pump. It's all about pump induced pressure at the inlet and outlet being different, lower at inlet than the outlet means we can assign...

    Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

    I have to disagree on one point To circulate the coolant, the pump must produce a pressure difference between inlet and outlet otherwise it ceases to be a pump. The pump producing a pressure difference has to be "a thing" in order to get some coolant circulation. some pressure is also necessary...

    Did I really mess this up? Rough alignment issues (uneven tie rod length) after steering box and spindle replacement

    its worthwhile scanning ebay for an alignment kit from the 70s one that uses wheel clamps that only go as big as 15 inch. i.e useless to most workshops these days because cars have bigger wheels i picked up a set near where i live in the UK for £50 swivel plates 2 wheel clamps 2 long...

    Anti Freeze question

    the "not allowed at the track argument" is usually its more slippery so more dangerous if spilled its flammable. which doesn't make much sense waterless coolant is propylene glycol Normal coolant is 40-60% ethylene glycol both glycols are flammable if you try hard enough propylene glycol...

    no idea about OEM But a denso mini alternator of a kubota digger and a bracket set from mancini does the job and saves weight. like a tiny birdcage alternator 36 amp 40 amp 70+ amp etc buy the smallest amps necessary something like this but i'd look out for an OEM Kubota or denso...

    Squeeling V belt and CVF alternator

    Squeeling V belt and CVF alternator

    I'm probably wrong but is the belt shown in the picture inside out....never seen one with the segmented section on the outside, those "toothy" bits usually go into the V of the pulley don't they?? I only ask this because your picture looks to show a symptom we are used to seeing here in...

    ok so regardless of any degradation. id certainly flush out the radiator heater matrix and block its set up for the kinda fuel you could purchase 40 years ago. which i guess was unleaded fuel with little or no ethanol.. these days there is a good chance that it has some ethanol in it to...
