The finished block, all nice and clean. The steel shot cleaner at
Performance Unlimited made the cast iron glow with a gold tint under the
lights. A unique trick you can just barely see in the second photo - the
cam bearings are installed upside down. The machine shop then constructed a special
drill to put a .040 hole to control oil flow to the cam. This precluded
the need for restrictors in the oil passages from the crank. The block was
zero decked to promote turbulence with the open chamber heads. One piston is
actually +.003 out of the deck. Even with that, piston-to-valve
clearance minimum was .300
After align-honing the block and the crank polish, clearance
is set @ .0035 and end play @ .008. It turns real smooth
with only a finger touch. The oil scraper is from MPG products.
Rods have been shot-peaned and resized. Rod bearing clearance
is set @ .0025 with .015 side clearance. The double roller
chain with +4-0-4 crank gear is from PAW. The cam is set
straight up, which required the +4 crank gear setting. The
Melling HV oil pump has been deburred and the clearances
checked. The pump drive is a Motorsports chrome-moly item.
Loctite 271 helps retain the pump bolts, cover plate and
the thread-in pickup. Can't be too careful here. Warm oil
pressure is about 30 PSI at idle and 60+ at speed.
The new Milodon 9 quart pan looks really good The headers are
from Tubular Automotive. This is a "before" shot as we sent
them to HPC for coating. Note the pipe from #3 has been modified.
As delivered, these are designed for the Mustang chassis. To
work with the Falcon and not set the carpet on fire, the #3
tube must be moved forward about one tube diameter. The header
physically fits without this mod, but comes within a hair of
touching the firewall. Denting the firewall does not help (tried
that), the pipe must be moved. These are 1 3/4" x 34" with a
3" collector. They are of top quality construction and have
thick, ground flanges. I used 3/8 cad plated header bolts I
found at Pep Boys. The cad plating should resist rusting better
than the standard black oxide bolts.
