I'm not familiar with crate engines but maybe this will give you =
some
ideas.
=20
Oil pressure on my 260 never drops below 40 psi. Scuffing could be an
oiling issue.
=20
Is this a roller cam?
=20
Roller lifters tick a little when they start to go bad and just get =
louder
as they wear. Again this could be an oiling issue.

I am helping a friend with a Tiger we are reassembling after 10+ years =
of
being off the road. We purchased a 302/340hp engine from Ford Motorsport =
to
install in this application. We installed the engine without =
difficulties
with a front sump oil pan, new pickup and right angle oil filter from
motorsports. It has a air gap manifold, 600cfm Edelbrock and a =
pertronix
dizzy. The engine started and broke in without issues but after about =
seven
miles on the road it developed a knock. Dropping the oil pan we =
discovered
the #2 piston was scuffed around the skirt. Sent it back and Ford =
replaced
with another block claiming they couldn't determine what the cause was. =
The
new engine we had broken in by a local speed shop and dynoed. It put =
out
320 Hp which we expected. Reinstalled the engine and after about 20 =
miles
on the road it developed what sounds like a lifter tapping. With great
difficulty we removed the valve covers and started the engine. =
Everything
on the top end looks and feels perfect but we still have the tapping. =
Put
the engine back together and installed another set of exhaust headers =
with
copper gaskets and the proper sealer thinking we possibly could have a
cracked header or leak. The problem persists and I am afraid we may find
another scuffed piston. The oil pressure has never dropped below 20# =
even at
idle.
Has anyone out there experienced a similar problem with these engines of
have a suggestion as to what our issues may be. ? The people at Ford
Motorsports are scratching their heads!

Thanks,=20
