wow this was fun.

Cant wait to come back after shift tomorrow and see if it at least gave an effort


If your really in need, I have a dwell meter that I can send to you, but it is probably easier to go to swap meet.

I bought one of these a few yrs ago, gave it to an apprentice. Readily available.

Cheap but reliable, just beware, if you want the temp option, maybe 20 bucks more

third column is cam angle, 4th is point gap , 6 is spark plug gap

I dont think I got if you had the powerglide or the manual, but rule of thumb back then was around 4 BTDC

Before top dead center.

ok done off to bed be back tommorrow again slick thread

for informational purposes HEI started in 1974

@ billr hilarious we posted again at same time

proof it aint dead yet

Yeah points, test light blinking should be be a good thing

as billr wrote. First things first.

I'm just jealous your working on a 68 327

very rare gem.

Starter fluid is maybe a bit over kill, but these 327 back then came out stock with forged rods so might take the hit.

Also, check spark KV.

On point based system should be able to crank 25 KV.

Again, @ Chuck, I know you know this, just putting that out there for other ppl who have the chance yto get thier grubby hands on that sweet ride.

winks

:bat:



If gas is old, not enough juice to ignite.

I know you know this, I am just putting this info out to revive here a bit. Not every day you see a thread on a 68 impala with a OEM 327

So here is a link for those who want to learn.

Many years ago guys swapped their points dist for HEI to get rid of poinys An easy switch over!

That 28-32 deg is the dwell angle, the amount the dizzy should turn while the points are closed enough for current to flow through the coil primary. If you want to set the point gap mechanically, the rubbing-block for the movable arm of the points must be on the tip of one of the dizzy cam lobes. Setting gap is less accurate then using a meter and setting dwell angle, but good enough.
