so i ran the 3rd gen with the ls1 first run 20.0something. i couldnt get the cluch to grab for ****. the best run i had was a 14.2 at 104 mph. and the clush still wasnt grabing like it should. i know i should easily be in the 13s low 13s at that. i did some street runs yesterday whit it and once the cluch is hot its fine well almost. i need a new master cylinder. but yea a ls1 running a 20 haha
