First of all, I'd like to introduce myself. I'm Sarah Keister (obviously),I'm 18 and from eastern Iowa and I'm in the process of buying a 1993 Chevy Ex. Cab 4x4 with a 5.7L V8. The truck has 174 thousand miles on it and I don't know whether or not I should fix up the engine or just get a new one. I'm trading in a 2001 Civic so I should have some extra cash in order to work on it right away. But I must have money for dual exhaust and my lift kit Anyone that helps me in anyway, thanks in advance!!
