Another 255 V8 Question- Headers & Exhaust Manifold Compatibility

That 255 is a weird motor, I cooked mine due to loss of internal oil pressure with no sign whatsoever. That was 20 years ago, but it was quite the weezy motor from the get go. I bet everything Ford put into that motor was oddball, I wonder what they had parts left over from to use for the 2 years they ran the 255?

it wasnt that oddball of a motor. the heads were severely restricted, as was the intake and exhaust, but that could be cured by bolting on the heads, intake, and exhaust from a stock 302. the bore on those motors was 3.68" with a 3" stroke, and us inline six guys use those pistons in the old 250 to bump the compression up where it should be. also a cam swap does wonders for the little 255, and so do gears.
