im looking around at buying a 3rd gen. i know that sooner or later i will have to replace the motor, cause not everyone is an enthusiast to keep the car running correctly. i want to know who has good engines that a rebuilt, such as pettit racing, etc. i know that the big names aernt always the best and i welcome the smaller shops too. i want to have somethign that will last 50K miles atleast after all my precautions are taken care of. you know the reliability mods. i also plan on making it a track car/street car. any help will be great. there will also be a poll, please add as moany as possible on how you feel about the engine and the website. also would it be worth just getting a second motor and rebuilding that one with all the goodies as compared to just buying a big name engine?
