Well after my painful ls1 was bad when i swapped it in. I opted for a 5.3 and swapped it in. Had it running 3 days now with no problems. Small po300 code at idle but i believe that was low octane fuel because it runs like a champ.
On the way home tonight saw a older 4.6 mustang gt which sounded pretty healthy with some flames painted on it. He was leaving a gas station so i reved at him saw him pull out behind me a run me down. Gets up beside me and revs one time i rev back and we both stomp it from about 45 dead even. He jumps the middle of his door to my bumper but then it was all over i reeled him back him and drove right by him and left him. He turned off afterwards. Felt great
The truck really pulls hard in the middle and up top. Cant really tell down low much since its stock open rear with 3.42s. But im happy.
