What block is this 1982 block>?
The lifterbores may be the shorter pre 1985 bores, in which case converting it to a roller is somwhat involved and the lifters may starve for
oil.
please send over the part number for the 1982 block. --ford made some weird engines in 1979-1983 so it would be good idea to verify exaclty what this thing is.....
also with the E303 cam, you probably want to get an indexing timing chain and index it 2 to 4 degrees advanced if this is going to be a street car with an automatic.
if it is a manual and he doesnt mind a lopey idle then straight up is fine. -- you will have to run the timing a bit advanced to get this to idle well.
Dont forget the E303 is a STEEL cam, so you need a STEEL distributor gear.
