Slant Six Forum :: howto make a timming set...

: I see in the Slantsickness hotrod story DD used
: a Sealer Power 223-338 gear and a ?????
: crank and chain? I want to try and advance
: my cam to bring the power on sooner...

:
: You can purchase the off-set bushing kit where
: you drill-out the 1/4 dowel pin hole to 3/8
: and use a bushing to set the advance.
: Or,
: You can drill, off-set mill, file-out / grind
: the cam gear hole bigger, to allow the cam
: pin to move forward, use shims and a degree
: wheel to find the proper amount of advance
: then bolt the gear down there. I use a small
: piece of lead shot and a washer large enough
: to cover the oblonged hole, I basically
: smash the lead or shim stock into any
: freespace left over after the shift in
: position.
: DD

: Im pretty sure its a big block lower gear and
: chain, but not 100% sure.
: DusterNut

: Ok I knew that, I was just wondering what the
: PN was for the keyed gear and chain. I did
: some looking around in the books at work and
: the sealed power part number is subbed to a
: DynaGear number, C338 (I think, left my
: notes at work) and that gear is 28bux. This
: gear goes to a late 60's early 70's Dodge
: 225 truck...
:
: How much should I try advanceing? The cam
: doesnt seem to "come on" till
: 3000rpm. If I can bring that down a hair it
: will be matched with my torq converter. And
: someone pointed out on /6.com that one tooth
: was worth 9.3something deg. Figger in
: cheap-ass-timming-set stretch and im sure it
: will come out to 8deg. Anyone know if this
: cam has "built in" advance like
: the CompCams ones?

The only multi keyed lower gear I know of is the JP Performance set. The factory lower gear and chain is the same as the BB Mopar with a double roller chain. (C339 (?) for the lower gear) Forget about any "WAG" on setting-up a cam, the "move it one tooth" idea will be way to much (it works out to 18 crankshaft degrees, yes, all measurments are in crankshaft degrees) Get yourself a degree wheel and see where your setting is at now, if it is at zero, set the cam 4 to 6 degrees advance to bring in more low rpm torque.
