timing chain, radiator mods

[eric.henning]

I am in the process of having my radiator re-cored and after messing with the
fan shroud and radiator bracket,
1) I've decided to cut the bottom off the radiator holder and then re-attach
with my own brackets for easier rad removal
2) Cut the fan shroud in half so the upper part can remain stationary while the
lower half can be easily removed. Question: Somebody had some good directions
on how to do the shroud modification. now I can't find it, anybody know where
it is?

Also, I think I've decided to replace the timing chain. What's so bad about
using OEM type chain and sprockets? Lasted 100,000 so far and since you should
change them every 75,000 or 100,000, the hevay duty ones don't seem to buy you
much except lightening your wallet.

Might as well replace the water pump. It seems Cinnabar's water pump doesn't
have the backing plate (according to recent photos). Aren't they supposed to
OEM?

Thanks.

Hi Erik

The fan shroud mod can be found on the GMCWS site.

The Cloyes roller chain provides a number of advantages including better
precision in the link fabrication. That translates to better timing
control. According to Joe Mondello, he found run of the mill timing chains
had several degrees of slop in the chain. In a recent rebuild of a chevy
350 I found the same thing.

PS the price difference isn't enough to get me excited when compared to the
effort in installing a new one.

Eric,

Do what you gotta' do, but the radiator can be removed easily enough by
taking out the four bolts that hold the top of the radiator frame in place,
then lifting up and forward. No need to butcher the frame. The ground
clearance needed is almost identical.

That frame is irreplaceable except from a salvage coach.

Your coach, your $$$, my $.02,
Patrick
