494 Pontiac

[ADY]

I had the same rust on my 4 year old MSD-85551. My car always in a dry garage, but I've heard rust is accelerated by ionized air in the distributor.

Going to order a new dizzy from a shop up north
that makes a msd type dizzy but things are coated
Not sure where all the moisture is coming from.. no leaks

Scott,
Springs were not comp and had a bunch of bad angle
stresses on them before I put the shaft system on
Thought my engine builder replaced them
Now going to a comp cam compatible spring
Isky easy rollers all looked good (3000 miles on them)
Plenty of oil on the lifters and rockers thanks to the MR1
aftermarket Pontiac block.. Scoped the cylinder last night
and it looks good

Adam,
Reading on line Msd has an issue with rusting
They say it does not effect things... some racers
take it apart and spray with clear lacquer paint

So in talking to comp cams my springs at 525 open were not
strong enough for my Solid Roller cam.. they want 625-650
Problem is Comp does not make a spring for my head.. wonder why
Pontiac engine with a copy of a Cleveland canted valve head with
chevy BB valve train... should be easy.. not really

Pac Springs has a set but they are smaller diameter so I need
to change out lower retainer... his size is a couple thousands less
on the retainer so might have to have it machined

Never easy on this car
