I have a '94 Dodge Ram 1500 5.2L Magnum that just rolled past 200,000 miles
earlier this month and although it still runs well, it is showing its age
and the engine feels a little tired. The truck is paid for and insurance
is cheap, so instead of buying a new truck, however, I would like to fix
this one up. I have an '89 318 out of a B250 van sitting in my garage that
I would like to rebuild and swap the top end(heads, intake, etc.) and fuel
injection system from my truck onto so that I can put it in the truck. I
would like to stroke it during the build to get more cubes (and more
torque for towing), but most of the stroker kits I have found include
expensive forged pistons and are over $1000. I plan to keep the
compression fairly low and this engine will not see much abuse or high rpm
use, so cast pistons should be okay and would be prefferable due to my
limited budget. Does anyone know of a stroker crank that can be used with
stock type cast 318 pistons and rods? Maybe a 360 crank with the mains
turned down? Also, does anyone know of a good aftermarket cam kit for this
build? Thanks for your advice!
I understand that you're trying to do this on the cheap but it's not gonna
work. You can't just drop in a longer stroke crank and call it good. When
you stroke an engine, you're gonna need longer rods and the wrist pin will
probably be seated higher in the piston.
Plus grinding reliefs into the bottom of the cylinders to clear the
rods. Not worth all the money it would cost. I would sell both engines,
and buy a 360 crate motor, and spend some money cleaning up the chambers
(sharp edges around the plug area seem to be part of the pinging
problems 360s have, cleaning them up sure cured my 77's pinging issues)
and port match the heads to the intake gaskets. A friend has this set up
in a 94, and it's really decent. Runs ping free on 89 octane, and is
just slightly slower than my 03 hemi.
