I never overheated the car before, nor during the beginners autocross session, learning the track where she blew. Thought a car with 60k miles and a new top end could handle 60-80mph turns for twenty minutes....guess not!
Time for a whole new engine block after dumping 5k into the old one that lasted two months and about 200 miles on it. The ported AI heads were salvaged and the custom AI cam along with the new springs, Manley rods, etc.. I'm going 383 Stroker with forged internals now.
Bum luck or what else would cause a block to crack? It makes no sense to me!
