How can we increase the dreaded "low oil"
the 400's are renowned for?
I think restricting the
cam bearings is a simple process
Restricting the front main bearing as we did I feel is simple
and well worth it. I think a big item was obtaining the
correct
Rod and Main bearing clearances . This we did by having
the
Bearings torqued in their housing bores, and then grinding
the
crankshaft to obtain the clearance.
2)
How do the available intakes compare?
When it came right down to
it, the small runner Edelbrock I liked the
best. Now if it had a bigger cam the Weiand maybe a better
choice. I
think the Holley could use more cam and RPM.
3)
Do we see an advantage to a "Zero" deck height
piston when used with a closed chamber head?
I don't think we did
to bad with the 87 oct fuel and the compression
we were running (9.7-9.8:1). Anytime you can get your peak

with the minimum amount of ignition is a gain. We ran a
very low
30 degrees full advance. I feel the quench in this engine

How big of carb. do you really need?
The 600 Holley was to

Holley. This will depend on your camshaft and
intake. I think for just
a street application, a 750 would be to large, But if
raced it would be a
