Everyone is ALWAYS going to have there own opinion! I know a guy who has a LT1 TA and he has alot done to it and its gutted out and he is running high to middle 6's (1/8). Some people like the LT1 and some don't. Some things I do know about the "difference" is the LS1 is a 5.7L the LT1 is 5.7 but its actually a FULL 350 cubic in, the LS1 is not a FULL 350cubic in. BUT the ls1 is all aluminum. I do know that the Fbody LT1 has aluminum heads.
