I have a 1982 Capri with a 255 v8 , the 255 has 170,000 miles, has blow- by, (bad rings and/or valve guides)and no high performance parts are available for this particular engine.

I have a 302 engine(1982)it has a stock variable venturi carb, and this does not matter as I intend to replace both the junk carb and intake with edelbrock,the #8 cylinder had water/rust in it, and it is hard to tell if the head gasket blew.

what I would like to know is:

1) would having a "sleave" put in the #8 cylinder solve the water in cylinder problem?,does this require boring out the cylinder? and/or

a different diameter piston?

2) can this engine even be mounted in a 1982 mercury capri?

3)will this engine bolt up to my tranny that is on the 255v8(not sure what type of tranny it is,but I know it does not have overdrive).

I was told that all ford smallblocks were same size and trannys and

different makes/models are interchangeable?.

What I hope to achieve is this:

1) I dont care so much about cost and time, Im doing this partly for fun and education.(I dont care what the negative "experts" say).

2)30-50% stock/50-70% high performance, at very least: chrome moly rings/hydrolic lifters and roller rockers/edelbrock manifold and carb/possible porting of heads. and crank joarnal in one set of pistons is worn to the bone and will require machining./oil pump/connecting rods/bearings/etc./.....

Any info is greatly appreciated!!

A quick check is to ask Summit Racing. They have good techs.
