yeah well im still researching guys, well so far i took the motor apart.. sorta.. the machine shop is going to work on the heads, bascially they told me to pick a cam, then get a matching torque converter and rear end gears, as for exhaust so for i got the long tube headers, still dnt know which exaust? i was think of buying a corsa, and have the muffler company weld it up,, also note i dnt have a gas tank in the back i have a fuel cell in the trunk so i have plenty of space under there? i just wish to know which cam i can use that will sound lopey and rough idle like that vette in the video, remmeber guys this 5.3 is in a 68 firebird it needs to sound mean.. well thanks for all of yalls advice
