I was just wondering what people thought about the LT1 engine and the LS1 engine i personally like the Lt1 engine better and i think it is a much faster engine but other people have been telling me that an Ls1 is better which i do not believe at all I was wondering if u think that the LT1 is better or the Ls1 is better let me know what you think Thanks ---

My friend ran a traction limited 11.6 with his lt1 powered 96 ws6 formula firebird. The car was fully loaded with t-tops and working AC. I have not seen that many ls1 cars that could keep up with him. However, he had major engine work done and if the same work was done to an ls1 it would be just as quick if not faster. Personally I would go with the ls1 because parts for it are eisier to get and you have more options. ---

Personally I would go with the ls1 because parts for it are eisier to get and you have more options. if this was in stock form I call MAJOR BS… My best in stock form was a 13.76 @103 with a 2.0 60’. And that was with 50° air temps. If we’re talking which is better to mod… for parts availability LS1\>Lt1, for all out buildups (I’m talking serious high boost/N2O 4 digit HP numbers) I would have to give the nod just slightly to the LT1 due to the iron block; all the LS1 guys that I’ve heard of that are building crazy HP are all running the 6.0L iron block from the trucks. If you consider the 6.0L an LS1 (I’m leaning on that being cheating because it’s not a native LS1 block like the LT1 one is), then the LS1 is better. Also, the LS1 design in where everything is going, so even if the LT1 had some advantages, in time when the aftermarket keeps growing for the LS, the LT will not be growing as much or shrinking. ---
