That last answer was good., but to add to it, don't do it if you like A/C. For the H22 to fit A/C system has to be removed. Also, the handling will be affected by the bigger H22 motor. The car will be front heavier and you will feel it in the steering. Most shops will tell you this. For straight line drag racing, It is fine; On twisty roads, it won't handle as well as it does now.m Still, you'll have bragging rights and you can laugh at that Mustang that you've just blown away.
