I ordered this motor 9-25-17 I just got it put in in may it has about 91 break in miles on it as of now it runs great and has a great thump to it and that's with manifolds & cheap mufflers cant wait for the 500 break in miles to be over to try out headers & flow masters for more performance & sound this motor was great for my swap in a 79 Z28 everything fit...thanks pace performance anytime I get a chance to tell someone about you guys...I WILL.
