Re: 351c or 320c
This is an oil drain hole from the valley area back into the sump. It's for the oil that drains from the top of the heads (from the push rods squirting oil onto the rockers etc).
The holes are anything but neat! They look like someone has taken a hammer to the cast iron and smashed it. You may also find a similar hole toward the back of the valley area too I think.
Ouch, 4 quid per gallon! Thats about 10 aussie dollars, about double what we're paying and about four times the price of US fuel!
The capri will go well with a 351. Very light car!
