why would you do that they are the exact same motor

even if you got the LS6 from the Zo6 its practicaly the same block as the LS1 the only difference between the LS6 block and the LS1 block is the way the cooling lines are run..... and the only real difference between the LS6 motor and the LS1 motor is the heads they are 243 casting as opposed to the 241 casting in the LS1....

if i were you id get the 243 casting heads for about $850 for the pair and the LS6 intake for about $400, and have tons of extra power, or you can also get the Zo6 cam and have a LS6 that you can say you built your self


but the LS1 in the Vette and the LS1 in your car are identical no joke!!

Default 98 firebird engine question

The only reason i asked is bcause we recently had some flooding here in houston and water got in the engine and the motor i got was from a corvette and i wanted to know if it would fit in my firebird because i was also told that the engine would not perform right because of the PCM.. Is that true???
