Re: Can a steel flywheel be machined?

i dont have a dedicated flywheel grinder however i have a horizontal surface grinder and a rotary table i attach when i want to grind a flywheel. this only does flat or downwards stepped flywheels though, so for anything in-stepped i do on my big lathe - over the years i have found the best way is a...

Re: Quadrajet issues

we had quadrajets on various gmh products here in australia, im far from an expert but have set up quite a few - many of the later carbs in particular will have trouble getting enough idle fuel (the mixture screws will just about fall out you just cant get them rich enough without idle tube mods) re...

Re: 22RE or other SOHC

we drove the carby versions of these for years as work vehicles, flogged the absolute daylights out of them and they just kept coming back for more. full of tools and batteries in the back, total weight was 2200kg. fuel economy was odd, didnt seem to matter whether you babied it or drove flat out ev...

Re: 350 sbc reduce compression ratio or retard cam?

.. I have been told by a serious engine builder that retarding ignition timing works out better than lowering compression. In what application would that be? WOT? i can relay a real world experience of a WOT application that proved even that was not the case. a controlled circuit racing category th...

Re: Narrowing rods

im lucky, at my shop i have a surface grinder with magnetic chuck - line them all up on the bed, grind all 8 at once, demagnetise and done.
maybe there is a shop near you that has such a machine, it is such a quick process its not worth much $$.

Re: Jeep 4.0 ERH misfire

IIRC they had a bulletin on one of the injectors overheating due to heat coming up between the intake manifold runners off of the exhaust manifold. I'll see if I can find it. i did see that bulletin however this problem seems to show up cold, not hot, as when the car came to me 2 days ago it was ho...

Re: Jeep 4.0 ERH misfire

I would suggest a static compression test, and then an engine running compression test. If it has a valve spring or lifter problem it should show up with the engine running compression test. And of course you did not mention if you had a scan tool, misfire monitor should tell you which cylinder to ...

Re: Jeep 4.0 ERH misfire

Lifter failures were/are common on the “power tech” 4.0 motors. If I recall correctly 99-02ish model years were the ones I saw the majority of issues with. Run it with valve cover off see if there’s limited/no rocker arm movement. have done that and all rockers appear to be moving the same amount. ...

Re: Chevy 366 Tall deck

in my neck of the woods a good 366 is in demand to keep old grain trucks going. They were a great engine for their intended purpose. Brian For true. Out in the ass-end-of-nowhere, farmers use their kids and any available help to "drive truck" and get the grain to the silo. The mission statement of ...

Jeep 4.0 ERH misfire

Hi from Australia! Have a bit of a puzzling one, a mechanical workshop I do work for called me and said they had pulled a cylinder head off a 2005 jeep 4.0 due to a random misfire. When I got the head, I checked it out and found the usual type of wear for 240-odd thousand KM but nothing as such to c...

Re: Solid Lifter Differences

from my experiences the poly blocks do have more of a "cutout" in the top of the block/deck area for where the intake pushrods are aimed more of an angle to the rocker arms than the la. lifter angle is the same. cams interchange size wise but as walter said the lobe orientation is different due to t...

Re: Solid Lifter Differences

as far as im concerned the poly has even worse angles for the pushrods, for the inlet rockers at least. for the la they all became much like the polys pushrod angle for the exhaust. my memory is telling me the earlier polys (as in pre-1960??) had the dumbbell type. Certainly, a really original unmol...

Re: Solid Lifter Differences

the lifters dont provide any oil up to the heads/rockers as there is a passage for each head thats fed timed oil from the cam journals 2 and 4. i recall the factory slants and 273's i have mucked around with all seemed to use the dumbbells, but the poly engines i have mucked around with had either d...
