More from Dave on the 438 Clevor build:

"I tried hard to make the engine as durable and maintenance free as is possible
with this sort of build and that means making compromises mostly with the camshaft.
It's pretty mild so I don't think it'll be particularly high maintenance. The
biggest thing is to just pull the covers from time to time and have a look at the
valve train/lash etc. That'll tell you a lot. And I think that the valvetrain
will be the area of the engine that will require the most maintenance.

Since this engine is built using the Windsor design block I was able to get a cam
ground using an Everwear core. That's the two piece cam core with a gear that will
allow the use of a regular cast iron distributor gear. I used an MSD billet
distributor and just deburred the gear and adjusted the advance mechanism to make
the curve shorter and come in more quickly.

I've used profiles from this series in jet boat applications that have run on the
river every weekend for the last couple of years on a set of springs without trouble.
I'd probably just check the lash a couple of times a year with moderate use and then
plan on pulling the intake after about two years to inspect and probably replace the
lifters. From what I've seen with this spring they will still check good when it's
time to freshen the heads. I On the CHI's I deliberately gave them a wide seat even
though that probably hurts performance a little I feel that they will stay nice longer.
These are a very smooth lobe that are easy on parts, it's most certainly not a drag
cam. Also the fact that it's ground on a pretty large(Ford) base circle also softens
up the profile a little which helps."
