putting a smaller V8 in it will not solve the problem cause the problem is the car weights too much if you put a smaller V8 in it it will get destroyed anytime your out on the street and some guy wants to race you cut the weight of the car down and you will be fine cause once you put a V8 in it you insurance cost will go up plus the cost of the car your gonna pay all that etra money just so you can hear the sound of a V8 no thanks
