Re: Engine dissasemble
1) split port swap?
2) ported and polished heads and intakes
4) you could do a 4.2 short block swap if you found one cheap enough but then I wouldn't do this without doing #2 unless you just had high mileage and found a low mileage 4.2
5) mikes idea with the pistons but that one will get expensive.
Things that don't belong on a Mustang: 20+" wheels, altezza lights, halo headlights, neon underglow, body kits that don't come from saleen or roush.
