Please help a Newbie Build His LS1-Truck 6.0 Hello Folks,
I have purchased a Cadillac ESV which is basically an all wheel drive Cadillac version of the 1500 series Suburban with the 6.0L Vortech.
The car stock had 6.0L 6000 H.O. V8: 345 hp at 5200 rpm, 380 lb-ft torque at 4000 rpm.
I then added the stuff I knew about... brakes, suspension, and then the motor: A magnusen roots type supercharger with 6.5psi of boost and a Full exhaust system, Headers to tail. The car runs great, though I have no idea how much power I am getting at the crank.
Q1) Can anyone make an educated real world estimate here please?
Now the Questions:
Q2) IS the cam in this car different than others? How does it make more power then the other GM cars like Suburban or GMC? about 10 more?
I am ordering the following:
- AFR 62cc Heads (225cc)
- 9.5:1 Compression JE Pistons (thinking baout 9.0:1)
- Stan Stroker crank for a 402cuin with their rods, etc
Q3) The builder is telling me to go 0.030 over bore and get it to 408. Is this safe or worth messing with the block?
Q4) Does anyone know the stock Cam's specs. Considering a cam of stock duration, but just a bit more lift. Any suggestions? Or should I just leave the stock cams in.
Will have to go to a smaller pulley as the boost will drop a good bit with the increased displacement and free-er flowing heads. Would have even considered 8.6:1 compression ratio pistons but I just think the Magnuson is too eak of a supercharger and will not be able to supply enough boost.
Q5) any opinon here?
Q6) With the above setup, what do you think the naturally aspirated motor make as the blower will add 45% to that.
Q7) is there anything else that you would recommend? By the way this is a daily driver and I tow 2000lbs with it once a month, though when towing I do not abuse it...
Many thanks in advance
